HP BladeSystem p-Class power subsystem

HP provides two power subsystem alternatives to accommodate various environments and customer

needs. These two options are enclosure-based power and rack-centralized power. All server blades,

interconnect options, and management tools are fully compatible with either power subsystem.

The new HP BladeSystem p-Class 1U Power Enclosure provides hot-plug, fully redundant power for a

single server blade enclosure containing any mix of server blades and interconnects. This option is

ideal for small blade deployments such as in remote or branch offices or small and mid-size

businesses.

The HP BladeSystem p-Class 3U power subsystem provides hot-plug, fully redundant power for

multiple enclosures that would typically be deployed in racks in a datacenter environment.

Rack-centralized power provides an efficient way to support a large number of blades while

eliminating power cables and the clutter and cost of PDUs associated with traditional power schemes.

The 3U rack-centralized power subsystem includes the power supplies, 3U power enclosure, and a

power distribution option. The HP BladeSystem p-Class system can be powered from single-phase or

three-phase AC power or from –48 VDC power sources.

The power supplies for the 3U solution convert 200–240 VAC to –48 VDC to power server blades

and interconnect switches and are housed in a 3U power enclosure. The power supplies are

front-accessible, hot-pluggable, and can be configured redundantly. The power enclosures are rack-

mounted below the server blade enclosures that they support.
