4.3.4SAS Connector Interface

One x4 SAS (Serial Attached SCSI) connector is present on the RTM. When the MPRTM0020 is connected to a MPCBL0020 Single Board Computer, only three of the four high-speed serial interfaces is available on the SAS connector, because one port is already used for the on-board local SAS drive on the SBC. The remaining three ports are available as ports 0-2 on the SAS connector (as shown in Figure 14 on page 27) to enable users to connect to a SAS JBOD for remote storage purposes. Figure 10 shows the outline of the SAS connector and Table 5 provides pinout information for the connector.

Refer to the Intel NetStructure® MPCBL0020 Single Board Computer Compatibility Report for information on specific SAS cable and SAS JBOD models that have been tested and validated by Intel.
