The following subsections provide step-by-step instructions for connecting the SAS RAID controllers to SAS drives and SATA II drives, either directly or through an expander.

2.5.1Connecting a SAS RAID Controller with Internal Connectors to Drives

This section provides step-by-step instructions for connecting the SAS cable from the internal connectors on the RAID controller to SAS drives and SATA II drives.

Follow these steps to connect your RAID controller with internal SAS port connectors directly to SAS drives, SATA II drives, or both.

Note: The SAS 9260-8i RAID controller is shown as an example. You can connect other SAS controllers with internal SAS port connectors in the same way.

Step 1. Insert the SFF-8087 x4 internal mini SAS connector on the cable into a SFF-8087 x4 internal mini SAS connector on the SAS 9260-8i RAID controller, as shown in Figure 2.5.
