Mixing Adapters Within a given family, several different adapters can be supported. However, HP
recommends that all adapters must be of one type only; a mix of both types of adapters is not supported.
InfiniBand Double Data Rate All components in a network must be DDR to achieve DDR performance
levels.
Myrinet Adapters The Myrinet adapters can be either the single-port M3F-PCIXD-2 (Rev. D) or the dual
port M3F2–PCIXE-2 (Rev. E and Rev F); mixing adapter types is not supported.

The QsNet

high-speed interconnect from Quadrics, Ltd. is the only version of Quadrics
interconnect that is supported.
1.7 Large-Scale Systems
A typical HP XC system contains from 5 to 512 nodes. To allow systems of a greater size, an HP XC system
can be arranged into a large-scale configuration with up to 1024 compute nodes (HP might consider larger
systems as special cases).
This configuration arranges the HP XC system as a collection of hardware regions that are tied together
through a ProCurve 2848 Ethernet switch.
The nodes of the large-scale system are divided as equally as possible between the individual HP XC
systems, which are known as regions. The head node for a large-scale HP XC system is always the head
node of region 1.
