Space Issues - HP ProLiant DL140 - G2 Server Introduction Manual

Space issues

The 1U and blade server form factors allow for high-density installations that can occupy 100 percent
of the front U space in a rack. This leaves only rear U or side ("zero U") space for mounting power
distribution components. HP has designed components to address space issues that are becoming
more acute in today's high-density systems. HP modular power distribution components include a
control core module that offers flexible mounting options as illustrated in Figure 3.

HP Monitored PDUs are self-contained in an extension strip form factor and designed to mount
vertically in the same manner as the extension strips shown in Figure 3.
Note that some server systems may occupy most of a standard-sized rack space. They leave little
room for power components or cables. These systems may require a rack extension kit (Figure 4) to
accommodate cables and PDUs and to allow access to field-serviceable components. Two optional
rack extensions kits, a 42U kit and a 36U kit, are available for the HP 10000 series equipment racks.
