Creating Pools Using Express Configuration
Adaptec Storage Manager offers two methods for creating pools—express
configuration and custom configuration. This section describes how to use the
express configuration method.
For instructions on creating pools using custom configuration, see "Step 3:
Note
Creating RAID Pools" on page 38.
About the Express Configuration Method
When you use express configuration, Adaptec Storage Manager automatically
creates pools by grouping together same-sized physical disk drives, and assigns
RAID levels based on the number of physical disk drives in a pool:
• A pool with three or more physical disk drives is assigned RAID 5.
• A pool with two physical disk drives is assigned RAID 1.
• A pool with only a single physical disk drive becomes a simple volume, which
does not offer redundancy.
To create a pool with any other RAID level, you must use the custom method,
Note
as described in "Step 3: Creating RAID Pools" on page 38. See "RAID Quick
Reference" on page 199 for more information about RAID levels.
SAS and SATA disk drives are grouped in separate pools. The maximum number of
pools created depends on the number of disk drives in your iSCSI Storage
Appliance. Up to 20 pools are supported on a single iSCSI Storage Appliance.
Pool size is set by Adaptec Storage Manager and automatically maximizes the
capacity of the disk drives. Pool size can't be adjusted during creation, even using
custom configuration. (To change pool size after a pool has been created, see
"Adding Capacity to a Pool" on page 90.)
