Chapter 4: Installing the HostRAID Controller and Disk Drives l 28

6Optional—Connect your HostRAID controller’s I2C connector (not available on all models) to an I2C connector on an internal backplane or enclosure, using an I2C cable.

7Connect your disk drives, following the instructions on page 30 for SAS controllers or page 32 for SATA controllers.

Selecting Disk Drives

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, refer to the Adaptec Storage Manager User’s Guide or Adaptec Storage Manager online Help.

Adaptec SAS HostRAID controller supports both SAS and Serial ATA (SATA) I and II disk drives. For cable information, see next section.

Selecting SAS Cables

You need one SAS cable for each disk drive you are connecting to your SAS HostRAID controller. Depending on your requirements, you can use any of these cables:

Internal SAS (SFF-8484) to SAS (SFF- 8484) cable

External miniSAS (SFF-8088) to SAS (SFF-8470) cable

External SFF-8470 to SFF-8470 cable
