Large HP XC Cluster of Server Blades
Figure 2-3 (page 37) illustrates a large HP XC cluster of eight regions, with 32 enclosures per
region.
There is a Gigabit Ethernet switch for the HP XC system that is connected to a Gigabit Ethernet
switch in each region.
The Gigabit Ethernet switch in a region is connected to each enclosure's Gigabit Ethernet switch
in bay 1 and to a ProCurve 2650 switch. The ProCurve 2650 switch is connected to the Primary
Onboard Administrator External Link of each enclosure.
