SURVEY TOPLINE Compared to peers who have a smaller percentage of their data centers, respondents who have adopted virtualization technology across more of their data operations experience 1. Better returns on infrastructure investments 2. Greater confidence in virtualizing a wider range of applications 3. More effective, comprehensive use of virtualization tools 4. Faster adoption of performance-accelerating infrastructure 5. Sharper focus on performance and manageability These data points correlate regardless of the size of the data center, indicating that IT teams of any size can gain significant benefits from implementing virtualization across more of their operations.

PREFACE The mindset with which an organization approaches its virtualization initiative has a profound effect on its success. Forrester researchers James Staten and Galen Schreck describe a progression in how organizations (regardless of size) evolve to adopt virtualization. This path to virtualization maturity outlines the actions and mindset of organizations as they move toward fully exploiting the technology s benefits. Note that every stage of this progression focuses on the experience, knowledge and operational requirements of the organization virtualizing its infrastructure, not its size or budget. Any organization no matter how large or small can significantly boost the efficiency and value of its environment by committing to a long-term vision for its implementation of virtualization technology.

THE SURVEY Virtualization is well-established as a key strategic technology in large enterprises, delivering the scalability and agility needed to handle the vast data growth and shifting business priorities that define these organizations. Many organizations with smaller IT teams are also adopting virtualization, some to address a specific tactical need and others as part of strategic initiatives to become more nimble and efficient. To learn more about this growing trend, Imation surveyed more than 1200 IT professionals (predominantly in enterprise organizations with 100-1000 employees), asking a variety of questions related to their use of storage systems in environments. Survey responses indicated multiple levels of experience with virtualization, ranging from small- scale implementations to enterprise-wide deployments encompassing hundreds of virtual servers and vast quantities of storage. This report reveals indications of where smaller IT teams see the greatest advantages from virtualization, and how increased adoption is creating new storage priorities and trends in the market.

THE SURVEY Wide-scale virtualization deployments are common among large enterprises, but smaller organizations are increasingly adopting the advantages of a comprehensive, long-term approach to virtualizing their IT operations. The majority of survey respondents come from organizations of similar size (100-1000 employees), yet their environments range from less than 25 terabytes to more than a petabyte of total storage. This illustrates the appeal of virtualization to a broad cross-section of IT operations. 14% RESPONDENTS TOTAL STORAGE IN VIRTUALIZED ENVIRONMENTS 7% 251-500 TB 101-250 TB 5% 501-999 TB 5% > 1 PB 39% < 25 TB 30% 26-100 TB PAGE 6
1 BETTER RETURN ON INFRASTRUCTURE INVESTMENTS Doing more with less is a fundamental requirement when competing against organizations with substantial budgets and extensive IT departments. Achieving such efficiencies demands a thoughtful, strategic approach to both the deployment and management of a virtualization initiative. Consolidation ratio (the average number of virtual machines residing on each physical server) is a key measurement of efficiency in environments. When more virtual machines can be consolidated, fewer physical servers are deployed and managed, reducing costs and complexity. Organizations with more of their operations gain greater consolidation efficiencies. Respondents virtualizing at least 60% of their environment are largely achieving consolidation ratios of 15:1 up to 25:1. These organizations enjoy related efficiencies including reduced hardware costs, less management complexity, lower power and cooling costs, and greater agility in scaling and reapportioning server and storage resources as needed. RESPONDENTS CONSOLIDATION RATION BY PERCENT OF DATA CENTER VIRTUALIZED 44+132+116+108= 100% 60+156+140+44= 80% 68+164+128+36= 60% <8 9-15 16-25 >26 128+196+68+12= 40% 316+68+12+4= 20% PAGE 7
2 CONFIDENCE IN VIRTUALIZING APPLICATIONS Common applications such as websites and databases are low hanging fruit for virtualization projects. Because these applications are relatively straightforward to bring under a hypervisor, organizations are often comfortable working with these as pilot applications, learning as they go. Unfortunately, some organizations stop with these tactical implementations, robbing themselves of the benefits that a fully- operation can bring to their operation. As forward-thinking organizations move ahead on a well-considered virtualization path, the experience breeds success with more specialized, and frequently more complex, applications as reflected in these results. These IT teams are able to free these applications from technology siloes, running them on flexible, heterogeneous platforms. In turn, this approach usually brings even greater efficiencies in manageability, performance, and availability.

3 MORE EFFECTIVE USE OF VIRTUALIZATION TOOLS Organizations that fully exploit the capabilities of virtualization technology are characterized by deep product knowledge and broad deployment experience. For example, VMware vsphere APIs for Array Integration (VAAI), integrated into vsphere, delivers significant storage performance and management benefits. Yet when survey respondents were asked if they had implemented VAAI, it became clear that awareness was much more prevalent among organizations that had placed more of its operation under a hypervisor. Among respondents with 20% or less of the data center those who may be virtualizing in a tactical or test mode 3 out of 4 respondents were unaware of VAAI. RESPONDENTS VAAI AWARENESS AND PLAN 2% 23% 11% 45% 26% Conversely, about half of those surveyed who have 30% 80 to 100% of their environments are either using VAAI or are in active consideration. Leveraging their deeper experience and familiarity with virtualization technologies, these organizations are positioning 20% 60% themselves to achieve far better performance than their competitors at no additional cost through a deeper knowledge of the tools of the virtualization process. implemented considering no plan / not aware 23% 59% 29% 100% PAGE 9
4 MORE USE OF STORAGE ACCELERATION TECHNOLOGY Virtualization makes very different demands on storage than a traditional physical server architecture. The heavily randomized read/write operations inherent to operations challenge organizations to boost storage system performance while maintaining cost efficiencies. To meet these challenges, organizations of all sizes are increasing their deployment of flash storage or solid-state drives (SSDs). Here, respondents using solid-state technologies are categorized by the total amount of storage supporting their operations. Hybrid storage, which uses a small amount of flash to accelerate affordable disk-based storage, is the #1 method of integrating flash, and those organizations with more storage under a hypervisor choose any flash option more than those with less. This, again, reflects a different mindset about infrastructures from organizations with a deeper experience with the technology.

5 MORE PRIORITY ON PERFORMANCE, MANAGEABILITY Out of 20 different selections, respondents top three choices are shown here. While performance was a primary concern for all of the respondents, those with greater amounts of storage under operations tended to place the most value on attaining the highest possible system performance. This practice tends to maximize overall operational performance, particularly when accelerated with flash storage. By contrast, respondents organizations with less storage under virtualization appear to be more concerned about the price/performance metric typically used in traditional physical infrastructures. The third highest priority cited by survey respondents relates to storage manageability. Respondents demonstrated preference for unified SAN/NAS systems that provides a single solution for presenting shares and LUNs simultaneously. Note that organizations with larger storage deployments place even greater emphasis on the significant management benefits of unified storage. RESPONDENTS TOP THREE PRIORITIES FOR CHOOSING A STORAGE VENDOR 25% Price/Performance 364= 20% 15% 10% 5% 0% 256= Raw Performance 256= 364= Unified Storage 112= 192= <250 TB >250 TB <250 TB >250 TB <250 TB >250 TB PAGE 11
