547 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 antistatic 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 "DoubleWide Modules" on page 87 for details on setting up double-wide bays in the AB7000 enclosure.
