Which HP Server solution is optimized for data center virtualization to achieve the highest density, maximize power efficiency by sharing power supplies and fans, maintain total flexibility through…

HP ML (tower) servers are standalone units that do not share power or cooling with other servers and provide no single-pane chassis management or interconnect module slots.

HP BladeSystem (BL) enclosures share power supplies and fans across all installed blade servers, directly maximizing power efficiency and physical density within the data center. The Onboard Administrator provides a Single Point of Management for every server and interconnect module in the chassis, and the c-Class enclosure supports the full range of HP Virtual Connect and other interconnect technologies, satisfying every stated requirement.

HP DL (rack) servers are independent 1U-4U rack units; each requires its own power supplies and fans and does not participate in shared chassis management or interconnect fabric.

HP SL (Scalable System) servers are optimized for scale-out HPC and dense compute workloads and do not emphasize shared power, single-point management, or the broad interconnect flexibility that characterizes BladeSystem.
