Managing SAS IOMs
The internal connection of the storage subsystem is called "Fabric C", which serves as a communication mode between compute
sleds and storage enclosures. The "Fabric C" is used for SAS of FC storage connectivity and includes a midplane. SAS IOMs
allow creating storage assignments in which you can map storage enclosure drives or whole storage enclosures to compute
sleds. SAS IOMs provide multi-path input out access for compute sleds to drive elements. The active module manages the SAS
IOM and is responsible for all inventory and storage assignments on the fabric.
A single width compute sled can support one Fab-C mezzanine card that connects to each IOM through a x4 link. Each lane in
the link supports 12Gbps SAS for a total of 48Gbps link to each SAS IOM. In SAS IOMs, the Fab-C IOMs are used to provide
SAS switching between compute sleds and internal storage sleds such as PowerEdge MX5016s.
For information on the tasks that you can perform on the I/O Modules page for SAS, see Managing IOMs.
SAS IOM Overview
The SAS IOM Overview page displays details of the IOM, chassis, the list of recent alerts, and recent activities. The IOM
information comprises of the model, power state, firmware version, fabric type, and management role of the IOM. The
management roles can be of three types:
