Leverage IBM eX5 Systems* for Huge Cost and Density Improvements

Executive Summary
As applications, workloads, and data multiply in enterprise organizations, inefficiencies in data center operations become more pronounced, resulting in higher costs, whether directly through expenditures such as energy bills, equipment purchases, and licensing, or indirectly through greater claims on resources such as administrative staff.
Addressing the ever-growing amount of data and the number of applications in the data center by adding more and more x86 servers has resulted in uncontrolled server sprawl and its attendant costs in electrical power, real estate, administration and maintenance, and equipment. An often-cited adage regarding data center hardware management costs sums up the situation thus: “Every penny spent on hardware requires a dollar to manage.” Consolidating servers through virtualization on single physical servers has become the de facto approach to reining in server sprawl, thereby minimizing costs, simplifying deployment, and streamlining management with single-point-of-management software.
Many organizations are not fully leveraging the virtual capabilities of their servers, because they configure a median of under ten VMs per server when they could be configuring many more. In fact, the average VM density falls far short of the true capital and operational savings that virtualization can achieve, which really starts to become very significant at as little as a 30:1 server consolidation ratio, well within the reach of even a modest data center in a smaller business. Organizations also encounter constraints in their ability to scale single VMs in order to accommodate expanding transaction processing or database implementations.
The amount of addressable memory a given server can access is the single largest roadblock to higher VM densities and scalable VMs. Modern servers must be equipped with far larger memory ranges per processor than previous designs. Even now, the memory addressability limitation of many popular servers is one of the bottlenecks driving customers to purchase more systems than is needed to meet their performance requirements, which results in their running more physical servers with underutilized processors. This can be very costly. In addition, it could help explain why IT managers often believe, mistakenly, that high-density virtualization and its associated economy of scale is available only to enterprise organizations.
