The interconnect network is a private network within the HP XC system.
Typically, every node in the HP XC system is connected to the interconnect.
The interconnect network is dedicated to communication
between processors and access to data in storage areas. It provides a high-speed
communications path used primarily for user file service and for communications
within applications that are distributed among nodes of the cluster.
Table 1-3 lists
the supported interconnect types on each cluster platform. For more information
about the interconnect types on individual hardware models, see the cluster
platform documentation.

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.
QsNetII. The QsNetII high-speed interconnect
from Quadrics, Ltd. is the only version of Quadrics interconnect that is supported.
