Preparing for Hardware Installation
▼
To Prepare for Hardware Installation
1. Read “Safety Agency Compliance Statements” on page 117 .
2. Familiarize yourself with the physical features of the Sun StorageTek SAS
RAID Internal HBA and the RAID levels that it supports.
See “Component Layout” on page 3 .
3. Ensure you have the right quantity of initialized disk drives for the RAID level
you want to use for the arrays.
See “Selecting the Best RAID Level” on page 101 .
All the disk drives must 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 Sun StorageTek RAID Manager Software User’s
Guide or online Help.
The Sun StorageTek SAS RAID Internal HBA supports both SAS and SATA disk
drives.
4. Ensure that you have the proper cables for the HBA and disk drives.
You will need one SAS cable for each disk drive you are connecting to the HBA.
Use only Sun-provided SAS cables (provided to you with your Sun system at the
time of purchase). For more information or to purchase cables for your Sun
system, visit the Sun web site at

. Cable connectors are
keyed so that you cannot insert them incorrectly.
