Selecting Disk Drives and Cables

Disk Drives

Your SAS controller supports SAS disk drives, SATA disk drives, and SATA and SAS Solid State Drives (SSDs). When selecting disk drives for your RAID array, ensure that all the disk drives have the same performance level. You can use different-sized disk drives in the array, but the array will be limited to the capacity of the smallest and slowest disk drive. For more information about arrays, refer to the Adaptec Storage Manager User’s Guide or online Help. For more information about compatible disk drives, refer to the Adaptec Web site at www.adaptec.com/compatibility.

Cables

Depending on your requirements, you can use any of these cables:

External mini-SAS (SFF-8088 to SFF-8470)—

Connects to an external SAS enclosure.

Internal mini-SAS with power (SFF-8087 to SFF-8482)—Connects to four SAS or SATA disk drives.

Internal mini-SAS to SATA fan-out (SFF-8087 to 4x SATA)—Connects to four SATA disk drives.
