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.
Note:
For any blade to access the InfiniBand module, it must first
have an InfiniBand card installed on its mainboard. See “Appendix
A: Troubleshooting” on page 581 for details on the Mezzanine
HCA cards that are available for use with the InfiniBand module.
Installation and Configuration of
InfiniBand Switch Modules
This section covers the installation, removal and configuration of
InfiniBand switch modules and InfiniBand pass-through modules.
Installing/Removing the InfiniBand Switch Module
Before installing the InfiniBand switch module make sure the cover to
the module has been installed before proceeding. Refer to the anti-
static precautions described in “Electrostatic discharge precautions” on
page vii.
The InifiniBand switch module must be installed into a double-wide
bay. Assuming that you have already created a double-wide bay out of
two single-wide bays, continue with the steps below. See “Double-
Wide Modules” on page 87 for details on setting up double-wide bays
in the AB7000 enclosure.
