[. . . ] The BL e-Class consists of the ProLiant BL 10e, a front-end server blade that supports a single, ultra low-voltage Intel® Pentium®-M processor and fits in a 3U enclosure. The p-Class product line consists of the ProLiant BL20p and the BL40p. The ProLiant BL20p is a mid-tier server blade that supports two Intel XeonTM DP processors. The ProLiant BL40p server supports four Intel Xeon MP processors and is ideal for back-end applications such as databases and messaging applications. Interconnects Each ProLiant BL server blade has multiple, redundant embedded NICs. Individual category 5e specified signal traces on the passive backplane of the server blade enclosure route network signals from the NICs to the interconnect options installed in the enclosure. Multiple interconnect options for ProLiant BL server blade enclosures give customers flexibility to choose the solution they prefer. Patch panel options provide pass-through of network signals while interconnect switches provide integrated Ethernet switching, significantly improving cable management for the rack and facilitating the rapid deployment of ProLiant BL server solutions. Power infrastructure The ProLiant BL power infrastructure is decoupled from the individual server blades and provides redundant power throughout the rack. Two 1+1 redundant hot-plug power supplies provide power directly to the e-Class enclosure using either 110 or 208 volts alternating current (AC). The two power supplies convert the power to 600 watts each of direct current (DC) that is shared by all server blades in the enclosure. A cable fault or other failure on the enclosure interconnect will not take enclosed server blades off line. Server blade functions will continue with less status information available about the rack environment and the power subsystem. Solution sizing To assist in planning and preparing a site for installation of ProLiant BL servers, HP developed a ProLiant BL p-Class and e-Class sizing utilities. These utilities include brief reference specifications about ProLiant BL products and their components. The utilities contain interactive calculations that generate site planning information such as floor space requirements, power distribution requirements, and environmental specifications based on criteria entered by the user. By starting with the number of server blades and server blade options to be installed in each rack, the sizing utility helps users determine: · The amount of DC power each rack will require for reliable operation. · ProLiant BL power infrastructure needs for specific installations. · The amount of facility AC infrastructure and AC load required to support each rack (that is, how many power circuits will be needed and the amount of power that will be drawn off each). · The amount of heat load that each rack of ProLiant BL servers will generate in the data center (for sizing the cooling infrastructure). · The approximate weight of and floor space required for each rack of ProLiant BL servers (for planning floor loading). HP has also developed a set of white papers for guidance in establishing a deployment infrastructure and power planning. [. . . ] If that server blade should fail at some later time and be replaced, the new server blade would automatically seek out the deployment server and download the pre-assigned script to configure itself identically. In other words, the new server blade would automatically take on the role of the failed server blade, significantly reducing the time and effort needed to keep servers in production. This "rip and replace" functionality is unique to the ProLiant Essentials Rapid Deployment Pack and ProLiant BL server blades. Use of the ProLiant Essentials Rapid Deployment Pack maximizes customers' IT resources by providing a full server build from a remote, centralized deployment console for initial power on, automated component configuration on the fly, and installation of standard software sets based on customerdefined server configurations.
