SATA Host RAID
With the Adaptec RAID Configuration Utility (ACU), you can create and manage RAID arrays with drives connected to a SATA
controller. This section explains how to use ACU and two host RAID levels to provide the proper level of fault tolerance and
event notification. See " SCSI Host RAID ."
HostRAID supports the following RAID levels:
RAID 0 — Striping mode for boosting performance
RAID 1 — Mirroring mode for data security
Creating Arrays
Before creating arrays, make sure the disks for the array are connected and installed in your computer. Note that disks with
no usable space, or disks that are part of the RAID array are shown in gray and cannot be used. See "Configuring Drives."
To create an array:
1. Turn on your computer and press when you are prompted to access the ARC utility.
2. From the ARC menu, select Array Configuration Utility (ACU) and press .
3. From the ACU menu, select Create Array by using the up- and down-arrow keys.
4. Select the disks for the new array and click Insert. To deselect any disk, highlight the disk and click Delete.
5. Press when disks for the new array are selected.
The Array Properties menu displays.
Assigning Array Properties
NOTE: Once the array is created and its properties are assigned, you cannot change the array properties using the
ACU.
Tips for assigning an array:
Before adding a new drive to an array, back up any data contained on the new drive. Otherwise, all data will be lost.
