Detailed introduction to supported I/O modules

Overview of the supported optional I/O modules available for use in your system.

Review these sections to learn about the uses, features, ports, and LEDs for the supported optional I/O modules.

Four-port 12-Gb/s SAS

Where supported, the four-port (x16 lane) 12-Gb/s SAS I/O module comes with four x4 lane mini-SAS HD (High Density) ports, one power/fault LED, and a combination link/activity LED for each port. Install this I/O module into the SP to provide additional SAS buses. Labeled 12Gb SAS v1.

NOTE:The optional back-end 12-Gb/s SAS module is not supported on all Unity storage systems.

The four-port 12-Gb/s SAS I/O module can also be configured to support x8 lane cabling for the 80-drive DAE by combining ports 0 and 1 as back-end 2, or ports 2 and 3 to create back-end 4. The I/O module can also be configured to support both x4 lane and x8 lane back-ends simultaneously.

NOTE:If the 12-Gb/s SAS I/O module is to be configured for x8 lane cabling, the x8 lane cable must be inserted into the I/O module before persisting it. If the x8 lane cables are not inserted into the I/O module first, all four ports default to x4 lane ports.
