The 3U, 15 (3.5-inch) DAE LCC supports the following I/O ports and connector on the rear:
Two 6-Gb/s SAS x4 ports
◆
One management (RJ-45) connector to the SPS (not used)
◆
6-Gb/s SAS x4 ports
The 3U, DAE LCC supports two (one input and one output) 6-Gb/s SAS x4 ports (labeled
6GB SAS 0 x4 and 1 x4) on the rear of each LCC (A and B). This port provides an interface
for SAS and NL-SAS drives on the DAE. This port is a 26-circuit 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.
Note: Each SAS cable is keyed with an
