Four 6-Gb/s PCI Gen 2 mini-SAS ports
◆
One management (RJ-12) connector to the SPS
◆
One USB connector
◆
6-Gb/s mini-SAS x8 ports — The DAE ICM supports four (two input and two output) 6-Gb/s
mini-SAS x8 ports on the rear of each ICM (A and B). This port provides an interface for
SAS and NL-SAS drives in the DAE. The port is a 26-circuit mini-SAS small form-factor
8088 (SFF-8088) specification (socket or receptacle) using an SFF-8088 specification
mini-SAS 26-circuit cable (plug) with a pull tab.
