5 European Server Infrastructure Market 2008 Top 10 Predictions Server Technology Predictions 1. x86 servers will gradually increase their market dominance against enterprise systems and make inroads in all vertical industries. 2. Virtualization will become a more mature technology with an increased focus on management tools. 3. Virtualization will move from a technology discussion to a broader business value discussion and will come to be known as "virtualization across the enterprise." 4. Blades will continue their double-digit growth on the EMEA server market in Vendors will intensify their focus on the midmarket and release solutions tailored to the needs of this segment. 6. Green computing will become a key differentiator in vendors' marketing strategies. 7. Windows Server 2008's long march to completion will finally reach the finish line during the first quarter of 2008, but mainstream adoption will drag well into Automation will play an important role as IT organizations control costs, improve service delivery, meet compliance regulations, and manage virtual resources. Go-to-Market Predictions 9. The number of partnerships between vendors will increase. 10. Server revenue from the channel will grow. Nov-08 5

6 Some Current Data Centre Challenges Data Centre devices are typically under-utilized Servers 25% Storage 40% Network I/O 40% PCs 5% Operational spending is overtaking capital spending due to higher energy costs, salaries, consumerables, etc.. High management overheads due to skills shortages, a lack of systems management tools, etc Many applications are hard-wired to their underlying systems creating widespread duplication and server sprawl Introducing new applications is difficult you have to find a service window, separate development from production, etc.. Nov-08 6

7 A Common Definition for Virtualization Virtualization is the disassociation of a data process from its underlying physical environment... is sometimes making a big thing look like a number of smaller things, for instance: Where a single machine is partitioned into two or more physical or logical devices Where from a management perspective a single machine appears to be multiple devices, with each capable of being addressed independently So, a computer will appear to be multiple computers, a storage system a number of storage devices, etc... is sometimes making a number of smaller things look like a single big thing, for instance: Creating a single system image or device from a number of separate parts, as in a) a number of Web services looking like a coherent corporate application suite, b) a data library sitting atop a number of separate storage systems, or Nov-08 7

8 A Definition of Server Virtualization Where a physical server is divided into two or more physical or logical servers. The outcome is that a single server appears to be multiple servers, capable of running multiple operating system instances and/or applications with some degree of isolation on dedicated hardware resources.

10 Virtualization and System Management Software Predictions Virtualization will be used to increase server utilization; the "virtualization effect" will see a slowing in overall unit growth rates but ASVs will increase as systems are shipped more richly configured. Impact: A significant number of large enterprises already use virtualization, impacting around a quarter of the installed base. In this segment upwards of 50% of servers are expected to be virtualized over the coming year. Virtualization will drive sales of new and more richly configured server systems. Impact: Systems need richer specifications to achieve the projected ROI benefits of virtualization from a consolidation and utilization standpoint. More virtualization and system management software products will be introduced to coordinate and pool together hardware resources, with the objective of making IT resources as flexible and changeable as possible. Impact: Will accelerate server consolidation trends in the mid term. Nov-08 10

25 Key Findings on Virtualization Virtualization Adoption is Rapid 35% of servers purchased in 2007 were virtualized and with an expectation that 52% of those bought in 2008 will be virtualized. 54% of those not currently running virtualization expect to do so in 2008 or Virtualization Use is Getting More Complex and Widespread Growth is in use for backup and availability as well as virtualization for strategic benefit. Skills and Licensing Hold Virtualization Back Availability of skills and application vendor licensing are the factors causing most problems for virtualization users. 23% of virtualization users report that their application vendors' licensing is still not meeting their needs and 33% of large businesses report that it limits use of virtualization.

27 Governments turning to Energy efficiency Nov-08 27

28 Datacenter Thermodynamics Predictions Power wastage in the datacenter has a significant impact on overall "power capacity." Green IT will be a major theme though business elements and constraints will drive the agenda rather than environmental concerns. Impact: Power wastage comes from both unutilized servers and overprovisioning of cooling; this is being addressed by virtualization to increase utilization and the following of datacenter best practice together with dynamic cooling solutions. In doing so facilities managers will free up power capacity. Today the lack of power capacity and over-provisioning of cooling capabilities act as an inhibitor, but looking forward best practice and virtualization require little investment. Dynamic cooling solutions require more planning and higher investment. Server footprints will continue to shrink (i.e., increased penetration of blades), placing pressure on power and cooling capacity of datacenter facilities. Impact: While penetration of blades is low at present it is expected to rapidly increase through the forecast period, which, if current trends continue, will see power and cooling capacity exceeded. Nov-08 28

29 Datacenter Thermodynamics Predictions Existing power infrastructure continues to lag datacenter requirements. Vendor strategies focus on increasing ROI associated with power investment at all levels. Impact: Power capacity acts as the glass ceiling denoting how many systems can be housed within the datacenter. Datacenter power and cooling infrastructure exceed capacity as a result of increasing server density. Impact: High cost of upgrading power and cooling infrastructure will impact other areas of IT budget. This will be felt strongest in SMB sector where to date the issue is not widely recognized. Corporate and Social Responsibility Purchasing process will be impacted by environmental concerns. Impact: Green computing is a "nice to have" which can be used for marketing purposes. There remains a perceived cost in being "green" and therefore the impact will not be felt until legislation is put in place forcing the issue. Nov-08 29

30 Some Conclusions Greece is a small (but strongly growing) market, telecoms and hardware are dominant components Virtualization can help simplify complex systems and infrastructure The disassociation of a data process from its underlying physical environment It can be helpful to think about the role it plays in the industry s submarkets (including the services, storage, server and software) If implemented well virtualization has a number of important business and technical benefits Majority of companies understand the importance of environmental factors but only few apply green criteria for purchasing-decisions Nov-08 30

31 Recommendations CIOs Should use virtualization to drive change in their infrastructure from silos of IT to the long promised "cloud" of resources. Virtualization Providers Need to differentiate through partnerships and advanced technologies. Cost saving is important but given the lack of measurement of costs it may prove a mixed argument. IT Services Providers Should note the relatively short length of virtualization projects and either fit to this or expand their engagement to a complete look at their customers' infrastructure.
