Medium Sized HP XC Cluster of Server Blades
Figure 2-2 (page 36) provides two illustrations of a medium sized HP XC cluster of 32 enclosures
and a maximum of 512 nodes.
The top portion shows a Gigabit Ethernet switch (a ProCurve 2848) that is connected to the
enclosure switch in bay 1 of each enclosure as well as to a ProCurve 2650 switch that connects
to the Onboard Administrator external link of each enclosure.
The bottom portion provides some additional detail. It shows the ProCurve managed Gigabit
Ethernet switch connected to the Gigabit Ethernet switch of each enclosure and to a ProCurve
2650 switch, which connects the Primary Onboard Administrator External Link of each enclosure.
