26 EMC VNXe3100 Hardware Information Guide
Overview
6-Gb/s SAS ports — The VNXe3100 platform SP has two 6-Gb/s SAS ports (labeled 6GB
SAS 0 x4 and 6GB SAS 1 x4) on the rear of each SP (A and B). These ports provide 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 connector (socket or receptacle) using an
SFF-8088 specification mini-SAS 26-circuit cable (plug) with a pull tab.
Note: The 6GB SAS port 1 x4 is not used at this time.
Figure 11 shows an example of the port connector (socket) and cable connector (plug)
with pull tab.

Note: Each SAS cable is keyed with an
in
(or one black circle, ) and
out
(or one black
diamond, ) connection to prevent incorrect cabling.
Table 4 lists the 6-Gb/s SAS port pin signals used on the connector.
