Chapter 4: Installing the HostRAID Controller and Disk Drives l28
6 Optional—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.
7 Connect 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
