Customer Scenario
Analysts estimate that organizations spend U.S.$0.50 on power and cooling for every dollar spent on new hardware, and this is expected to quadruple over the next five years. Server virtualization and consolidation can reduce data center energy needs. However, virtualization requires tremendous memory and performance capacity; consolidation only increases risk. To fully realize data center virtualization benefits, organizations must implement a solution that is customized to their needs; has energy-efficient disk drives and processors; has the memory and I/O performance needed to support virtualized operating systems and applications; and has built-in reliability and redundancy to help ensure continuity and end-user productivity.
IBM + Microsoft Solution
Before building a virtual data center, it is essential that organizations collect the right foundational information, including knowing what to virtualize, which applications work well in a virtualized environment, and what type of utilization they need. Without the proper plans and guidance, organizations can be left with virtual machine sprawl, high costs, and severely diminished virtualization benefits. That is why Microsoft and IBM recommend working with vendors that have experience designing virtual infrastructures and understand how to help optimize these technologies.
Organizations must also keep in mind the goals that their business decision makers have for the virtual data center, such as disaster recovery, security, and scalability. This will enable them to allow for the appropriate efficiencies, power and space constraints, and storage requirements that must be built into the infrastructure strategy. Using all of this knowledge, organizations can determine how many virtual machines they want to run per server, which will direct the decision about which hardware platforms are best suited to the data center environment.
Microsoft and IBM provide hardware and software virtualization solutions that are optimized for high-power, energy-efficient data centers:
IBM System x enterprise servers leverage decades of mainframe server design to deliver an open and affordable, industry-standard server platform that can help tackle the most demanding workloads. The ideal platform for highly consolidated, virtual server environments, these servers deliver higher throughput and exceptional reliability.
IBM BladeCenter blade servers deliver optimal performance for enterprise environments with expanded memory and processor performance. They offer high density for better processor-to-memory performance, provide simplified local storage with rugged solid-state drives, and are optimized for the virtual data center with high-speed I/O and expanded memory.
Windows Server 2008 with Hyper-V consolidates multiple server roles as separate virtual machines running on a single physical machine so that users can efficiently run multiple operating systems—Windows, Linux, and others—in parallel, on a single server, and take advantage of the 64-bit operating environment.
