Server Blade Quantity

For site planning, the assumed quantity of server blades should be the total number of server blades
that will be deployed over the life of the installation. Planning for growth is necessary to ensure that
you purchase the appropriate power subsystem components (power enclosures and bus bars) and
quantities of server blade enclosures. Additionally, growth sizing enables the pre-configuration of
ample power to ensure that the HP BladeSystem can be expanded as your business grows.
If you mix server blades in a rack with traditional servers and storage, you should allow for space in
the rack, weight, and power of additional devices.

Configuring server blade options

For accurate site planning, server blade option entries should be the aggregate total number of all
options to be installed in the server blades over the life of the installation. Options such as processors
and hard drives can have a significant effect on power consumption, heat generation, and system
weight.

HP BladeSystem server blade enclosures

The number of server blades determines the required quantity of enclosures. Each enclosure has ten
slots; two of these are reserved for interconnects and eight are designated for server blades. Table 24
shows the capacity of a server blade enclosure:

To plan for future growth, additional server blade enclosures can be installed in advance enabling
rapid server deployments as needed. The HP BladeSystem p-Class Sizing Utility summary page
indicates the appropriate number of enclosures and required power for the configuration specified by
