InfiniBand Module
4-1 Overview
InfiniBand is a switch-based, point-to-point bidirectional serial link network
communications architecture. The main function of the SuperBlade InifiniBand switch
module is to provide high-speed interconnectivity among the blade modules and
external peripherals. This is a hot-pluggable module that must be installed in a
double-wide bay at the lower right of the enclosure. Because it occupies one of the bays
alternatively used for the CMM, only one InfiniBand module may be installed in the
system.

NOTE: For any blade to access the InfiniBand module, it must first have an
InfiniBand card installed on its mainboard. See Appendix A for details on the
Mezzanine HCA cards that are available for use with the InfiniBand module.
