whitepaper Memory Sizing for Server Virtualization2007-09-05 Intel
  Intel IT has standardized on 16 gigabytes (GB) of memory for dual-socket virtualization hosts. We based this decision on extensive analysis of maximum physical memory consumption on more than 3,000 servers running non-virtualized workloads in our business computing environment. We found that approximately half of these servers consume 1 GB of memory or less. For workloads of this size, we believe that we can achieve high consolidation ratios of up to 15-20 to 1 using low-cost dual-socket virtualization hosts based on quad-core processors. We expect that this strategy will minimize cost because we avoid paying for unused memory and associated power and cooling.

whitepaper Information Provider Cuts Costs and Improves Disaster Recovery With Virtual Machines2007-09-01 Microsoft
  Kroll Factual Data delivers Web-based business information to companies such as mortgage lenders and property management firms. In 2003, Kroll Factual Data acquired a company with only 98 hours left on its lease. To avoid paying for the leases on two data centers, Kroll Factual Data chose to migrate the acquired data center onto virtual servers. After an initial deployment of VMware ESX Server, Kroll Factual Data deployed Microsoft Virtual Server 2003 R2 Enterprise Edition. Today, the company hosts one of the largest known deployments of Virtual Server 2005 R2, with more than 1,400 virtual machines running on 345 physical server computers. As a result of deploying Virtual Server, Kroll Factual Data has reduced expenses and improved system stability and flexibility.

whitepaper Solution for Open Virtualization Helps Provide Server Consolidation2007-09-01 Intel
  Using virtualization to decrease the number of servers required to support enterprise workloads presents cost savings opportunities. Organizations that want to take advantage of the latest virtualization technologies can face a complex task, in terms of both design and integration. Novell, IBM, and Intel are helping to reduce that complexity, with a solution for open virtualization and products/ services (available separately) that encompass the entire lifecycle.

whitepaper Server Consolidation and Virtualization: Issues and Actions2007-08-30 BMC Software
  Many IT organizations today have an abundance of servers, most of which are underutilized. According to various industry estimates, servers typically operate at five to 20 percent of full processing capacity. Underutilization is a major contributor to high data center costs, which include money spent on power, cooling, floor space, administration, and software license fees. The costs scale in direct proportion to the number of servers installed. This over-provisioning of servers not only drives up costs, but because servers are typically siloed and dedicated to specific applications or jobs, it also hampers business agility. Consequently, it's difficult to repurpose servers to meet changing business needs.

whitepaper Virtualization Best Practices2007-08-23 CA (Computer Associates)
  There is a lot of hype around virtualization. One common virtualization goal is to improve the way in which IT manages its resources. This may take the form of increased peak capacity, improved resilience, reduced configuration costs, and reduced configuration management errors. One or more of these goals is often attainable. Perceived virtualization savings may also take the form of reducing the amount of hardware that IT purchases or manages. Although there may be some debate as to how (and why) hardware reduction should be done, there is little doubt that virtualization has value and is most definitely here to stay.

whitepaper Sun Microsystems' Solutions for Virtualization Across the Enterprise2007-08-01 Sun Microsystems
  Virtualization is quickly becoming an important technology across all parts of the IT environment. The technology is rapidly being deployed in server, storage, networking, as well as client environments. By far the most visible adoption of virtualization technology is happening in servers - from the largest Unix server down to the smallest volume system. Virtualization is being used as a tool for consolidation, a means to reduce space and power requirements, and more recently as a way to bring business continuity to a larger part of an organization's IT infrastructure. The key to these benefits is that virtualization software both encapsulates the software stack and decouples it from the underlying hardware.

whitepaper An Evaluation of Server Consolidation Workloads for Multi-Core Designs2007-07-13 University of Wisconsin-Madison
  While chip multiprocessors with ten or more cores will be feasible within a few years, the search for applications that fully exploit their attributes continues. In the meantime, one sure-fire application for such machines will be to serve as consolidation platforms for sets of workloads that previously occupied multiple discrete systems. Such server consolidation scenarios will simplify system administration and lead to savings in power, cost, and physical infrastructure. This paper studies the behavior of server consolidation workloads, focusing particularly on sharing of caches across a variety of configurations. Noteworthy interactions emerge within a workload, and notably across workloads, when multiple server workloads are scheduled on the same chip.   
whitepaper FailSafe Server Consolidation2007-06-25 ZeroNines Technology
  Server consolidation is a flavor of virtualization. Server consolidation implements the virtualization concept. Virtualization is a venerable principle of computing systems design. With virtualization, an application software program calls system resources such as storage, peripherals or special processors, as if the application has exclusive access to them. A resource manager, such as an operating system, furnishes access to the resources while managing resource contention. The application can be low-level, such as network software or database, or high level, such as a business application. Virtualization simplifies application design, development, deployment and management - so everyone in the IT value chain is a stakeholder.   
whitepaper Automotive Services Retailer Shrinks Data Center by Half, Cuts Operational Costs2007-06-08 Microsoft
  Midas is one of the world's largest automotive service providers, including exhaust, brakes, steering, suspension, and maintenance services. There are more than 1,700 franchised and company-owned Midas locations in the United States and Canada. The Midas data center contained many older server computers running unsupported business software. Midas needed to consolidate its servers to create a more stable environment and reduce the size of the data center. It also wanted to minimize the costs in hardware, consulting fees, and rewriting software for the new environment. Midas migrated 16 older servers to 4 physical servers running Microsoft Virtual Server 2005 R2. The company reduced hardware migration costs by 53 percent and made the transition without consulting help.

whitepaper Server Consolidation: Business Considerations for a Successful Outcome2007-06-01 Technology Partners International
  Corporations are increasingly turning to server consolidation - an approach to the efficient use of computer server resources in order to reduce the total number of servers or server locations - as a means of minimizing future expenditures for hardware, maintenance and operating expenses. According to Forrester Research, Windows servers typically run at only 8 to 12 percent of their full capacity and UNIX servers at only 25 to 30 percent. Increasingly, most organizations are realizing the potential benefits of driving greater efficiencies from the current Information Technology (IT) footprint.
