Dana Gardner: Hi, this is Dana Gardner, principal analyst at Interarbor Solutions, and you’re listening to BriefingsDirect. Today, we present a sponsored podcast discussion on planning and implementing data-center virtualization at the strategic-level in enterprises.

Because companies generally begin their use of server virtualization at a tactical level, there is often a complex hurdle in expanding the use of virtualization. Analysts predict that virtualization will support upwards of half of server workloads in just a few years. Yet, we are already seeing gaps between an enterprise’s expectations and their ability to aggressively adopt virtualization without stumbling in some way.

These gaps can involve issues around people, process and technology and often, all three in some combination. Process refinement, proper methodological involvement, and swift problem management often provide proven risk reduction, and provide surefire ways of avoiding pitfalls as virtualization use moves to higher scale.

The goal becomes one of a lifecycle orchestration and governed management approach to virtualization efforts so that the business outcomes, as well as the desired IT efficiencies, are accomplished.

Areas that typically need to be part of any strategic virtualization drive include sufficient education, skilled acquisition, and training. Outsourcing, managed mixed sourcing, and consulting around implementation and operational management are also essential. Then, there are the usual needs around hardware, platforms and system as well as software, testing and integration.

So, we’re here with a panel of Hewlett Packard (HP) executives to examine in-depth the challenges of large scale successful virtualization adoption. We’ll look at how a supplier like HP can help fill the gaps that can hinder virtualization payoffs.

Please join me in welcoming our panel: Tom Clement, worldwide portfolio manager in HP Education Services. Welcome to BriefingsDirect, Tom.

Tom Clement: Thank you, Dana. Great to be here.

Gardner: We're also here with Bob Meyer, virtualization solutions lead with HP Enterprise Business. Hey, Bob.

Bob Meyer: Hey, Dana.

Gardner: And we’re here with Dionne Morgan, worldwide marketing manager at HP Technology Services. Hello, Dionne.

Dionne Morgan: Hello, Dana.

Gardner: Ortega Pittman, worldwide product marketing, HP Enterprise Services, joins us. Hello, Ortega.

Ortega Pittman: Hi, Dana.

Gardner: And lastly, Ryan Reed, worldwide marketing manager at HP Enterprise Business. Hello, Ryan.

Ryan Reed: Hi, Dana, thanks for having me.

Gardner: I want to start by looking at this notion of a doubling of the workload supported by virtualization in just a few years. Why don’t we start with Bob Meyer? Bob, tell me why companies are aggressively approaching the move from islands of servers to now oceans of servers.

Headlong into virtualization

Meyer: Yeah, it's interesting. People, had they known an economic downturn was coming, might have thought that it would have slowed down like the rest of IT spending, but the downturn really forced anybody who is on the front to go headlong into virtualization. Today, we are technically ahead of where we were a year or two years ago with virtualization experience.

Everybody has experience with it. Everybody has significant amounts of virtualization in the production environment. They’ve been able to get a handle on what it can do to see what the real results and tangible benefits are. They can see, especially on the capital expenditure side, what it could do for the budgets and what benefits it can deliver.

Now, looking forward, people realize the benefits, and they are not looking in it just as an endpoint. They're looking down the road and saying, "Okay, this technology is foundational for cloud computing and some other things." Rather than slowing down, we’ll see those workloads increase.

They went from just single percentage points a year and a half ago to 12-15 percent now. Within two years, people are saying it should be about 50 percent. The technology has matured. People have a lot of experience with it. They like what they see in results, and, rather than slow down, it's bringing efficiency to things like the new service model.

Gardner: Ortega Pittman, do you see any other issues around these predictions? The expansion of virtualization seems to be outstripping the skill sets that are available to support it.

Pittman: That's where HP Enterprise Services comes to add value with meeting customers' needs around skills. Many, times small, medium, and large organizations have the needs, but might not have the skills on hand. In providing our outsourcing services, we have the experienced professionals who can step right in and immediately begin the work and the strategic path towards their business outcomes.

The skill demand and the instant ability to get started is something that we take a lot of pride in, and in the global track record of doing that very well is something that HP Enterprise Services can bring from an outsourcing perspective.

Gardner: Dionne Morgan, what are some of the risks, if folks start embarking on this without necessarily thinking it through at a life-cycle level? Are there some examples that you have experienced, where the hope for benefits -- economic and otherwise: agility benefits, flexibility, and elasticity -- somehow end up being imperiled by not being prepared?

Morgan: Many people have probably heard the term "virtual machine sprawl" or "VM sprawl," and that's one of the risks. Part of the reason VM sprawl occurs is because there are no clear defined processes in place to keep the virtualized environment under control.

Virtualization makes it so easy to deploy a new virtual machine or a new server, that if you don’t have the proper processes in place, you could have more and more of the these virtual machines being deployed and you lose control. You lose track of them.

That's why it's very important for our clients to think about not only how they're going to design and build this virtualization solution, but how they're going to continue to manage it on an on-going basis, so they keep it under control and they prevent that VM sprawl from occurring.

Gardner: We’ve talked about this people, process, and technology mixture that needs to come together well. Tom Clement, from that perspective of education, are there things about virtualization that are dramatically or significantly different than what we might consider traditional IT operations or implementation?

Clement: Certainly, there are. When you talk about people, process, and technology, you hit upon the key elements of virtualization project success. There is no doubt in my mind that HP provides the best-in-class virtualization technology to our clients hands down. But, our 30-plus years of experience in providing customer training has shown, time and time again, that technology investments by themselves don’t ensure success.

The business results that clients want in virtualization won’t be achieved until those three elements you just mentioned -- technology, process and people -- are all addressed and aligned.



The business results that clients want in virtualization won’t be achieved until those three elements you just mentioned -- technology, process and people -- are all addressed and aligned.

That's really where training comes in. Our education team can help address both the people and process parts of the equation. Increasing the technical skills of our customers' people is often one of the most effective ways for them to grow, increase their productivity and boost the success rates of their virtualization initiatives.

In fact, an interesting study just last year from IDC found that 60 percent of the factors leading to the general success in the IT function are attributed to the skills of people involved. In that regard, in addition to a suite of technical training, we also offer training in service management, project management, business analysis, all with an eye to helping customers improve and integrate their virtualization projects to better processes -- just as Dionne was speaking about a moment ago -- and to better process management.

Of course, we have stable and experienced instructors, whose practical, hands-on expertise provides clients with valuable tips and tricks that they can immediately use when back on the job. So, Dana, you hit it right on the head. It's when all three of those components -- people, process, and technology -- are addressed, especially in virtualization situations, that customers will maximize the business results that they get back from their virtualization solutions.

Gardner: We’ve also seen in the field that, as people embark on virtualization and move from the tactical to the strategic, it forces a rethinking of what it is core and what might be tangential or commoditized.

Ryan Reed, are we seeing folks who, as they explore virtualization, start also to explore their sourcing options? What are some of the trends that you're seeing around that?

Seeing a shift

Reed: Thank you for asking that question. We do see a shift in the way that IT organizations have considered what they think would be strategic to their end business function. A lot of that is driven through the analysis that goes into planning for a virtual server environment.

When doing something like a virtual server environment, the IT organizations have to take a step back and analyze whether or not this is something that they’ve got the core competency to support. Often times, they come to the conclusion that they don’t have the right set of skills, resources, or locations to support those virtual servers in terms of their data-center location, as well as where those resources are sitting.

So, during the planning of virtual server environments, IT organizations will choose to outsource the planning, the implementation, and the ongoing management of that IT infrastructure to companies like HP.

They apply our best practices and our standard offerings that are available to IT organizations from HP data centers or from data centers that are owned by our clients, which would be considered an on-premise type of virtual server environment. Then, they're managed by the IT professionals that Ortega Pittman had mentioned earlier in either an on-shoring or off-shoring scenario, whichever is the best-case scenario for the IT organization that's looking for that skilled expertise.

It's definitely a good opportunity for IT organizations to take a step back and look at how they want to have that IT infrastructure managed, and often times outsourcing is a part of that conversation.

Gardner: It also sounds like that rethinking allows them to focus on the things that are most important to them, their applications, their business logic, and their business processes and look to someone else to handle the plumbing. In the analogy of a utility, somebody else provides electricity, while they build and manage the motors. Is that fair?

Reed: That's a very fair statement. By choosing a partner to team up with to manage that internal plumbing, as you’d referred to it, it allows the IT organization to get back to basics, to understand how to best provide the best-in-class, lowest-cost service to their end users -- increasing business productivity and helping them maximize the return on their IT investment. This powers the business outcomes that their end-users are looking for.

Gardner: I'm intrigued by this notion that these organizations are going to be encountering virtualization sprawl and trying to expand the use of it, but in different ways are they going to be exercising strengths and weaknesses. What are some of the gaps that are typical? What do we usually see now in the field that create a stumbling block to the wider adoption of virtualization?

Pittman: One of the things we observe in the industry is that many customers will start with a kind of phase one of virtualization. They'll consolidate their servers and maybe stop just there. They get that front-end benefit, but that exhausts the internal plumbing that you referred to in a lot of different ways, and can actually cause challenges and complexities that were not in their immediate expectation. So, it's a challenge to think that you're going to start with virtualization and not go beyond the hypervisor.

The starting point

We’d like to work with our customers to understand that it's the starting point to consolidate, but there is a lot more in the broader ecosystem consider, as they think about optimizing their environment.

One of HP’s philosophies is the whole concept of converged infrastructure. That's thinking about the infrastructure more holistically and addressing the applications, as you said, as well as your server environments and not doing one off, but looking more holistically to get the full benefit.

Moving forward, that's something that we certainly could help customers do from an outsourcing standpoint in enabling all of the parts, so there aren’t gaps that cause bigger problems than the one hiccup that started the whole notion of virtualization in the beginning.

Gardner: Does anyone else has some observations from the field about what gaps these organizations are encountering as they try to expand virtualization use?

Clement: One of the good things for our clients is the fact that within HP we have a great deal of experience and knowledge regarding virtualization. Through no fault of their own, many clients don’t understand or don’t realize the breadth or depth of virtualization options and alternatives that are available for them.

We want to make sure that the customers are thinking about this first from the business perspective.



The good news is that we at HP have a wide range of training services, ways that we can work with a client to help them figure out what the best implementation options are for them, and then for us to help them make sure that those options are implemented with excellence and truly do result in the business benefits that they desire.

Gardner: Now that you’ve mentioned some of the strengths that HP is bringing to the table, how do you get those to work in concert? It seems that it's a hurdle for these organizations themselves to look at things holistically? When they go out to a supplier that has so many different strengths and offerings, how do you customize those offerings individually to these organizations. How do they get started?

Morgan: We think about this in terms of their life cycle. We like to start with a strategy discussion, where we have consultants sit down with the client to better understand what they’re trying to accomplish from a business objective perspective. We want to make sure that the customers are thinking about this first from the business perspective. What are their goals? What are they trying to accomplish? And, how can virtualization help them accomplish those goals?

Then, we also can help them with their actual return on investment (ROI) analysis and we have ROI tools that we can use to help them develop that analysis. We have experts to help them with the business justification. We try to take it from a business approach first and then design the right virtualization solution to help them accomplish those goals.

Gardner: It sounds like there's a management element here. As we pointed out a little earlier, IT departments themselves have been divvied up by the type of infrastructure that they were responsible for. That certainly makes a lot of sense, and it follows the development of these different technologies at different times in the past.

Now, we're asking them, as we virtualize, to take an entirely different look, which is more horizontal across this converged infrastructure. Is there a management gap that needs to be filled or at least acknowledged and adjusted to in terms of how IT departments run?

Blurring the connections

Meyer: What it calls into focus is that one thing virtualization does very nicely is blur the connections between the various pieces of infrastructure, and the technology has developed quite a bit to allow that to ebb and flow with the business needs.

And, you're right. The other side of that is getting the people to actually work and plan together. We always talk about virtualization as not an end-point. It's an enabler of technology to get you there.

If you put what we’re talking about in context, the next thing that people want to go to is maybe build a private-cloud service delivery model. Those types of things will depend on that cooperation. It's not just virtualization that that's causing but it's really the newest service delivery models. Where people are heading with their services absolutely requires management and a look at new processes as well.

Gardner: In many cases, that requires a third party of some sort to be involved, at least, to get that management shift or acknowledgment under way.

Which of you can offer an example of how we move to a higher level of virtualization and got those payoffs that people are so enticed by -- that much lower number of servers, lower footprint, lower carbon and energy use, total cost, etc.? Can you provide an example of an organization that's done that and has also bitten the bullet on some of the management issues that allows that economic benefit?

They decided to virtualize, because that would help, of course, with the ability to consolidate and to improve on those service levels.



Morgan: I can give one example. There's an organization called Intrum Justitia, a financial services organization in Europe. We worked with them as they were embarking out their virtualization journey. The challenge they had was that they have multiple organizations and multiple data centers across Europe, and they wanted to consolidate from 40 different locations around Europe into two data centers.

At the same time, they wanted to improve the service level they were providing back to their business. They decided to virtualize, because that would help, of course, with the ability to consolidate and to improve on those service levels.

The way we helped them was by first having that strategy discussion. Then, we helped them design the solution, which included the HP Blade System, VMware software, EVA Storage, as well as other hardware and software products. We went through the full lifecycle with them helping with the strategy and the design.

We helped them build the solution. We managed their project office. We managed the migration from the 40 locations. Then, once everything was transitioned, we were able to help them go on the right path to further managing them. Some of the results were that they were able to manage that consolidation to the twin data centers, and they're beginning to see some of the benefits now.

Gardner: Let me put you on the line. What do you think HP brought to the table in this example that the Intrum wouldn’t be able to find anywhere else?

Wide expertise

Morgan: There are a couple of things. One is that we actually have the expertise, not only in the HP products, but also in the software products. We have the expertise, of course, for the Blade Systems and the EVA Storage, but also the expertise around VMware.

So, they had hardware and software expertise from one vendor -- from HP. We also have the expertise across the lifecycle, so they could just come to one place for strategy, design, development, and the ultimate migration and implementation. It's expertise, as well as a comprehensive focused life goal.

Gardner: Are there any other examples of a larger scale, top tier organization that has moved aggressively into virtualization and had a success?

Pittman: Yes, Dana, HP Enterprise Services worked with the Navy/Marine Corps Intranet (NMCI), which is the world’s largest private network, serving and supporting sailors, marines, and civilians in more than 620 locations worldwide.

They were experiencing business challenges in productivity and innovation and in the security areas. Our approach was to consolidate 2,700 physical servers down to 300, reducing outage minutes by almost half. This decreased NMCI’s IT footprint by almost 40 percent and cut carbon emissions by almost 7,000 tons.

We minimized their downtime and controlled cost. We accelerated transfer times, transparency and optimal performance.



Virtualizing the servers in this environment enabled them to eliminate carbon emissions equivalent to taking 3,600 cars off the road for one year. So, there were tremendous improvements in that area. We minimized their downtime and controlled cost. We accelerated transfer times, transparency and optimal performance.

All of this was done through the outsourcing virtualization support of HP Enterprise Services and we're really proud that that had a huge impact. They were recognized for an award, as a result of this virtualization improvement, which was pretty outstanding. We talked a little earlier about the broader benefits that customers can expect, the services that help make all of this happen.

In our full portfolio within the IT organization of HP, that would be server management services, data center modernization, network application services, storage services, web hosting services, and network management services. All combined, they made this happen successfully. We're really proud of that, and that's an example of the very large-scale impact that's reaping a lot of benefit.

Gardner: We've talked about how this can scale up, I suppose it's also interesting in the future, as more companies look to virtualization and think about services and infrastructure as a service (IaaS), that this could probably start going down market as well. Does anyone have some thoughts about how a company like HP, perhaps through their outsourcing capabilities, could move somebody’s values into an organization smaller than the Navy and Marines?

Mission-critical systems

Reed: What's interesting about the NMCI is that, as Ortega mentioned, this is a very large complex and mission-critical system. Thousands of servers were virtualized, having a major impact on how the service is being delivered. The missions that are being performed on such an infrastructure are still mission critical. You can't really have a much more impactful implication, because lives actually depend on the successful missions that are performed on this infrastructure.

Now, if you take that and have it scaled to lower level implementations of virtual server environments, the lessons learned, the best practices, the technology, the people, the processes, and the skills are all absolutely relevant, when trying to scale this down to small- and medium-sized businesses.

That's because the standardized procedures for managing this type of infrastructure is documented for our service delivery organizations around the world to take advantage of. They’re repeatable, standardized, and consistently delivered.

Gardner: As we get into the future, and the use of virtualization becomes integral to more companies -- not as an island, but more of the ocean that they are sailing on -- this kind of changes the way the companies function. They'll become more IT services and service management oriented. Perhaps, they'll have more services orientation in terms of their architecture.

Does anyone have any thoughts about where this is going to lead next, if you bite the bullet, become holistically adept at virtualization partnering with companies like HP to use the skills and understanding they have and learn the lessons of the past? What are the next stages or steps? Bob, any thoughts?

Virtualization becomes a foundational element for the next set of service delivery model that people are looking at.



Meyer: We mentioned this in the beginning. Virtualization becomes a foundational element for the next set of service delivery model that people are looking at. So, from an IT provider’s perspective, if you get virtualization right, if you get the converged infrastructure that Ortega was talking about, you get the right mix and close the skill gaps. You get a strong foundation to move on to things like private cloud, and it really opens up your options for different service delivery models.

With this is this notion of pushing out virtualization more broadly, the next step leads you to a good place to build on top of those delivery models and ultimately lower the cost and increase the quality of the services you deliver to the business.

Pittman: You asked how it all fits in moving to the future. Recently, in a Gartner report, there were some key findings. One of the items that was reported was that mid-sized businesses are seeking a much more intimate relationship with IT providers. There is a perception out there that they can have a closer relationship with smaller vendors as opposed the large ones.

One thing I’d like to just put out there for the IT community that may be is thinking about virtualization is that HP offers solutions for small, medium and large organizations. The way we are set up in terms of the account support with our account leaders, we certainly can meet the needs of the small to medium to large menu. We are set up to engage, support, and be that trusted advisor at all three of those levels.

Just to dispel any misconception that "They’re large, and I'm not sure if I'm going to get the attention," we're ready and have the products and services to deliver outcomes that they are looking for at all levels.

Gardner: Sort of "have it your way" opportunity.

Pittman: Exactly.

Expertise and flexibility

Clement: Just to follow on to that point, which I think is a great one. As we've been hearing here, it boils down to expertise and flexibility. Does HP have the expertise strategically to help clients of any size? Do we have the expertise from a service delivery perspective, from an instructor perspective, from a course development perspective? And the answer is, we do.

Do we provide these services, these products, these training classes in a variety of flexible ways and are we willing to tailor these to our clients. The answer, again, is a resounding, yes, we are.

Gardner: I wonder if we could offer some concrete ways to get started. Are there some places people can go, some Google searches they should do, as they are thinking about virtualization and their expansion and their way of managing the risk?

Morgan: There is definitely HP.com. We have many pages on HP.com to talk about virtualization and our virtualization offerings. So, that is the one area. They could also contact their local HP representative. If they work with HP authorized channel partners, they can also have discussions with the channel partners as well.

Meyer: There's a very simple way to find out more about virtualization solutions. You could just type in www.hp.com/go/virtualization, and it will take you to virtualization home page. If specifically you want to find more about services, it's just www.hp.com/go/services. That shortcut will take you right to the very relevant information.

Gardner: Well, very good. We've been here with a panel of HP executives examining the in-depth challenges of moving to large scale successful virtualization adoption. We looked at some of the ways that HP has worked with some customers to help them make that leap successfully. I want to thank our panel today. We've been talking with Tom Clement, worldwide portfolio manager in HP Education Services. Thank you, Tom.

Clement: You're most welcome, Dana. Again, thanks for having me.

Time to Give Server Virtualization's Twin, Storage Virtualization, a Top Place at IT Efficiency Table

Transcript of a BriefingsDirect podcast on the improved business metrics from adopting a virtualized storage architecture.

Listen to the podcast. Find it on iTunes/iPod and Podcast.com. Download the transcript. Learn more. Sponsor: Hewlett-Packard.

Dana Gardner: Hi, this is Dana Gardner, principal analyst at Interarbor Solutions, and you’re listening to BriefingsDirect.

Today, we present a sponsored podcast discussion on storage virtualization. You've heard a lot about server virtualization over the past few years, and many enterprises have adopted server virtualization to improve their ability to manage runtime workloads and high utilization rates to cut total cost.

But, as a sibling to server virtualization, storage virtualization has some strong benefits of its own, not the least of which is the ability to better support server virtualization and make it more successful.

We're here to discuss how storage virtualization works, where it fits in, and why it makes a lot of sense. The cost savings metrics alone caught me by surprise, making me question why we haven't been talking about storage and server virtualization efforts in the same breath over these past several years.

To help us explain how to better take advantage of storage virtualization, we're joined by Mike Koponen, HP's StorageWorks Worldwide Solutions marketing manager. Hello, Mike.

Mike Koponen: Hello, Dana. How are you doing today?

Gardner: Doing very well. Thanks for joining us.

Koponen: You bet.

Gardner: As I said, a lot of folks have been taking up more server virtualization and understanding its benefits. It's become quite popular, particularly in the down economy, where cost is so important. Storage virtualization offers a number of the same types of benefits. Tell us why storage virtualization makes so much sense.

Economic environment

Koponen: Dana, you mentioned that, particularly in today's economic environment, customers need to boost efficiencies from their existing assets as well as the future assets they're going to acquire and then to look for ways to cut capital and operating expenditures. That's really where storage virtualization fits in.

It's a way to increase asset utilization. It's a way to save on administrative cost, and it's also a way to improve operational efficiencies, as businesses deal with the increasing storage requirements of their businesses. In fact, if businesses don't reevaluate their storage infrastructures at the same time as they're reevaluating their server infrastructures, they really won't realize the full potential of a server virtualization.

Gardner: A few years ago, people were putting in servers as fast as they could. Basically, their goal or their motivation was simply to keep up with demand. I have to believe that's the case with storage as well, and storage requirements are still growing rapidly. How do you both keep up with the high demand for more and try to cut cost at the same time.

Koponen: It's an excellent question and one that businesses deal with all the time. As you say, the storage requirements aren’t letting up from regulatory requirements, expansion, 24x7 business environments, and the explosion of multimedia. Storage growth is certainly not stopping due to a slowed down economy.

Storage virtualization and server virtualization are tools that businesses are using to deal with those. In the past, as you said, customers would just continue to deploy servers with direct-attached storage (DAS). All of a sudden, they ended up with silos or islands of storage that were more complex to manage and didn't have the agility that you would need to shift storage resources around from application to application.

Then, people moved into deploying network storage or shared storage, storage area networks (SANs) or network-attached storage (NAS) systems and realized a gain in efficiency from that. But, the same can happen. You can end up with islands of SAN systems or NAS systems. Then, to bump things up to the next level of asset utilization, network storage virtualization comes into play.

You can pool all those heterogeneous systems under one common management environment to make it easy to manage and provision these islands of storage that you wound up with.

Gardner: You mentioned this notion of silos of storage and I think I heard at least two or three different levels of silos of storage. Can you break that out for us? What are we really talking about, when we think about the various components at play here?

Three levels

Koponen: I break it down into three levels. One, I'd call basic virtualization. That's where you just have internal storage in your servers or direct attached storage to those servers. The next level would be what I'd call virtualized network storage. We've got SAN systems that have the ability to virtualize the arrays and the disk spindles within that SAN system.

The third level is what I call network-based storage virtualization. There, you have the ability for heterogeneous storage systems to all be managed under a common structure and virtualized as a single common pool of storage. Those would be the three levels that I break them down into.

Gardner: So, the goal with storage virtualization is not just to virtualize on each of those levels, but to virtualize them all together, so there is a single pool of storage. Is that correct, or that I am oversimplifying?

Koponen: No, that's basically it. In the second two levels I described, where you've got a SAN system, those can also come in two types. You can have a traditional one that's non-virtualized and then you can have a virtualized one, such as the HP Enterprise Virtual Array or the HP LeftHand SAN, where you have the ability to stripe data out across disk spindles and multiple drive trays, and all of that is abstracted from the system administrator.

There are different needs or requirements that drive the use of storage virtualization and also different benefits.



The storage is virtualized, and then the level above that is where you have network-based storage virtualization, such as our SAN virtualization services platform, that can take heterogeneous storage systems, multiple SAN systems for multiple vendors, and present those as one common pool of storage. It's this concept of pooling storage, but at different levels.

Gardner: Of course, it's a big management task to be able to do that and then get to the storage the way that you want to prioritize different storage requirements and some responses based on the application set or whether you're doing it for backup or archives. Is that right?

Koponen: That's true. There are different needs or requirements that drive the use of storage virtualization and also different benefits. You mentioned some of them. It may be flexible allocation of tiered storage, so you can move data to different tiers of storage based upon its importance and upon how fast you want to access it. You can take less business-critical information that you need to access less frequently and put it on lower cost storage.

The other might be that you just need more efficient snap-shotting, a replication of things, to provide the right degree of data protection to your business. It's a function of understanding what the top business needs are and then finding the right type of storage virtualization that matches those.

Gardner: It also sounds like we're taking a complete look at storage. We're looking at it from all angles and, therefore, are able to architect in such a way that we can take advantage of all the capacity we have and do that intelligently. Is that a fair assumption?

Key driver

Koponen: That's true. One key driver is boosting asset utilization. We found that in a lot of businesses they may have as little as 20 percent utilization of their storage capacity. By going to storage virtualization, they can have a 300 percent increase in that existing storage asset utilization, depending upon how it's implemented.

Gardner: Mike, tell me how this relates to server virtualization. If I've got a server virtualization program underway and I've enjoyed some benefits from that, what is taking this added step to storage virtualization going to do for me?

Koponen: Well, a couple of things, Dana. First, in order to take advantage of the advanced capabilities of server virtualization, such as being able to do live migration of virtual machines and to put in place high availability infrastructures, advanced server virtualization require some form of shared storage.

So, in some sense, it's a base requirement that you need shared storage. But, what we've experienced is that, when you do server virtualization, it places some unique requirements on your storage infrastructure in terms of high availability and performance loads.

Server virtualization drives the creation of more data from the standpoint of more snapshots, more replicas, and things like that. So, you can quickly consume a lot of storage, if you don't have an efficient storage management scheme in place.



Server virtualization drives the creation of more data from the standpoint of more snapshots, more replicas, and things like that. So, you can quickly consume a lot of storage, if you don't have an efficient storage management scheme in place.

And, there's manageability too. Virtual server environments are extremely flexible. It's much easier to deploy new applications. You need a storage infrastructure that is equally as easy to manage, so that you can provision new storage just as quickly as you can provision new servers.

Gardner: So, is this a case of a whole being greater than the sum of the parts? If we do server virtualization well and then we do storage virtualization well, not only do we get the usual benefits in terms of capacity, cost, flexibility, and intelligence at each of those perspectives, but, by combining them, we get something additional.

Koponen: Yes, you certainly do. The way I would describe that X factor of what you're getting in addition is just the highest level of business agility and flexibility. The underpinning of that would be that you're making maximum use of your assets, both your server assets and your storage assets.

Gardner: Is there something else here in terms of security, compliance, complexity, or those other necessary things to deal with nowadays? Do we get anything else in combining these two?

Increased protection

Koponen: You certainly get an increased degree of data protection by being able to meet backup windows and not having to compromise the amount of information you back up, because you're trying to squeeze more backups through a limited number of physical servers. When you do server virtualization, you're reducing the number of physical servers and running more virtual ones on top of that reduced number.

You might be trying to move same number of backups through a fewer number of physical servers. You also then end up with this higher degree of data protection, because with a virtualized server storage environment you can still achieve the volume of backups you need in a shorter window.

Gardner: So, it's better control, better understanding, higher utilization, and lower cost. If someone is interested after hearing this, where do you start, how do you undertake a journey? I assume you don't do this all at once, but rather it's something you need to do on a rollout basis. Where do you start when it comes to storage virtualization?

Koponen: Step one is assessing your environment and understanding what your starting point is going to be. Is it a greenfield environment, where you've got a lot of departmental, work-group type servers that you don't have tied into shared storage or virtualized storage? It might be starting with putting in place virtualized storage to support those.

You're more exposed now to that single physical server going down, because, if that single physical server goes down, you've lost multiple applications, and not just one.



Or, do you have existing SAN systems in place that are just underutilized. Then, you might look at putting in place, say, the HP SAN Virtualization Services Platform (SVSP), to get a higher degree of asset utilization out of the existing systems.

It depends on where you're starting from. So, step one is to determine that, figure out where your most underutilized assets are, and what's causing you the most pain today from a management complexity standpoint. Or, it could be the case that you don't have an adequate business continuity plan in place. That's your key factor in where to start. So, it's assessing that starting point, Dana.

Gardner: Let's drill into that business continuity one for a second. That's pretty important. What does virtualizing your storage bring to the table, when it comes to data recovery, disaster recovery, backup, archiving, or continuity issues?

Koponen: Well, first, when you virtualize your servers, you're taking multiple applications and running them on a single physical server. You're more exposed now to that single physical server going down, because, if that single physical server goes down, you've lost multiple applications, and not just one. So, the need for high availability goes up.

Server virtualization suppliers like VMware, Microsoft, and Citrix, all have capabilities to provide high availability on the application side. You need to make sure you match that with high availability on the storage infrastructure side, so that you've got the same capabilities within your storage from a high availability standpoint as you do your sever infrastructure.

Gardner: Right, it doesn't make sense to have the applications humming along at whatever requirements are, if the storage and data can't keep up.

High application availability

Koponen: Exactly. From an HP portfolio standpoint, we have some innovative products like the HP LeftHand SAN system that's based on a clustered storage architecture, where data is striped across the arrays and the cluster. If a single array goes down in the cluster, the volume is still online and available to your virtual server environment, so that high degree of application availability is maintained.

Gardner: Mike, how about some examples? For folks that have done this already, what are the typical scenarios? What are some of the paybacks? What's the usual case scenario?

Koponen: Dana, there was a white paper recently done by IDC on the business value of storage virtualization. It looked at a number of factors -- reduced IT labor, reduced hardware and software cost, reduced infrastructure cost, and user productivity improvements. Virtualized storage had a range of payback anywhere from four to six months, based on the type of virtualized storage that was being deployed.

It found asset utilization increases up to 300 percent, savings of administrative cost of 2x to 3x, and shrinking back-up times by up to 80 percent as well. The benefit in the payback was really compelling. That IDC paper is posted on the HP website.

Virtualized storage had a range of payback anywhere from four to six months, based on the type of virtualized storage that was being deployed.



Gardner: What are some of the business returns? Clearly, we've got some cost benefits and technology benefits that folks in the IT department would enjoy, but what would we expect from storage virtualization for the larger business outcomes or goals?

Koponen: You have these benefits of reduced CapEx and OpEx that companies can take to the bottom line, particularly in these economic times, and you also have improved business agility as well. Let's say, a company makes an acquisition and they've got to merge an existing IT resource into their existing IT infrastructure. The ability to do that is going to be greater, given that you've got a virtualized storage infrastructure in place.

Gardner: That gives more agility for changing your organization from a merger and acquisition perspective. How about sourcing, when it comes to what we think about now as cloud computing? Is there some benefit in having virtualized storage that gives you more options for your sourcing?

Koponen: Well, it gives you more options in terms of the flexibility with which you manage your internal cloud, how you can meet your quality of service levels to your internal user community, and how you partition out storage to them, because you can make much more efficient use of those resources. Using your outsourced cloud providers, you can augment that existing server and storage capacity that you've got in place.

Gardner: Returning to the road map of how you would get started and involved with this, what else do you need to consider other than certain technologies? Is this something that's going to change the nature of your organization? Are we going to be asking different folks inside of IT, and perhaps outside of IT, to work together in ways they hadn't before? What are the cultural implications?

Combining resources

Koponen: That's a good question, Dana. In the case of enterprise organizations, you may have the storage management done by a particular set of folks. Then, you may have the management of it, the server infrastructure, done by another set of folks. This will bring those two sets of resources together and provide them more efficient platform to be able to work together.

In medium-sized businesses, it's all about being able to manage storage assets without having to have expert storage administrators in place, so that server administrators can manage the storage assets as easily as they do their server assets.

Gardner: I wonder, if there's something we left out. Is there another item around this that folks should be aware of?

Koponen: I don't think so. However, for people who want to learn more about storage virtualization and what HP has to offer to improve their business returns, I suggest, they go to www.hp.com/go/storagevirtualization. There they can learn about the different types of storage virtualization technologies available. There are also some assets on that website to help them with the justification of putting storage virtualization within their companies.

HP has very strong relationships with all of the server virtualization suppliers in the marketplace, so that we can bring complete solutions to bear on customers.



Gardner: Just to be clear. When HP approaches storage virtualization, you're working with a number of different vendors and suppliers and different technologies. This is really quite a heterogeneous landscape. Is that correct?

Koponen: That's correct. HP has very strong relationships with all of the server virtualization suppliers in the marketplace, so that we can bring complete solutions to bear on customers. We use best-of-breed technology from the entire ecosystem.

Gardner: Well, thanks. We've been hearing about server virtualization in the past few years, but today, we've taken the time to look at a sibling, storage virtualization. It involves improved runtime workloads in the server side, getting the storage and data that it needs, but there is also a lot of pure, economic rationale for going about the storage virtualization on its own.
