Connecting the Cables This section describes the cables used on the SAS controller and provides instructions for connecting SAS and SATA hard disk drives to the SAS RAID controller. Note: Use only "straight" SAS cables, not "cross-over" SAS cables. A SATA connector consists of a signal connector and a power connector. The SAS connector adds a bridge (primary physical link) between the signal connector and the power connector. This means SAS backplane connectors can accept either drive type, but SATA backplane connectors can ONLY accept SATA drives. Figure 3 shows these connectors. Figure 3. SAS and SATA Plugs and SAS Backplane Connector Configuring the Storage Adapter After performing the Intel® RAID Controller SASWT4I installation, you must configure the storage adapter and install the operating system driver. The Intel® IT/IR RAID Software User's Guide provides configuration options and instructions for the Intel® RAID Controller SASWT4I, as well as detailed installation instructions for operating system drivers.
