Figure 4. Example of iLO Power Regulator reporting capability Server virtualization using virtual machine technology Several studies of the data center environment have shown that without server virtualization technology, typical x86 processor utilization rates range somewhere between 5 to 15 percent. IT administrators can use virtual machine technology (for example VMware, Microsoft Virtual Server, RHEL/XEN and SLES 10/Xen) to consolidate multiple older, physical server platforms onto a single more powerful and energy-efficient server platform. Therefore, virtualizing and consolidating servers can increase processor utilization rates, reduce capital expenses, and reduce operating expenses (such as physical space requirements, power, and cooling costs in the data center). To learn more about virtualization, refer to the technology brief titled "Server virtualization" technologies for x86-based HP BladeSystem and HP ProLiant servers" referenced in the section titled "For more information" at the end of this paper. Efficient practices at the rack level Rack configuration affects the ability to power, cool, and control the servers in the rack. Air flow, air leakage, power redundancy, power distribution, and cable management all contribute to the fundamental issues in highly dense computing environments. Rack configuration tools Using configuration tools can assist data center managers in optimizing rack configurations for compatible hardware. The HP eCo-Enterprise Configurator provides factory default racking for HP hardware portfolio. This tool allows the user to build virtual server solutions online. With it, the user can choose servers, memory, operating system, storage, backup solution; configure power and cooling options; select appropriate software; and assign necessary services and support.
