InfiniBand Modules

Overview

InfiniBand is a switch-based, point-to-point bidirectional serial link
network communications architecture. Acer offers three different
Infiniband modules:
• 4X QDR (40 Gb/s) switch with 20 internal ports and up to 16
external QSFP ports (3 models).
The main function of the AB7000 InifiniBand switch modules is to
provide high-speed interconnectivity among the blade modules and
with external peripherals. These are hot-pluggable modules that must
be installed in a double-wide at the lower right or top right of the
enclosure.
For any blade to access the InfiniBand module, it must first

A: Troubleshooting" on page 581 for details on the Mezzanine
HCA cards that are available for use with the InfiniBand module.
