Adding and Managing Storage Pools
A Storage Pool is a grouping of drives with a certain storage size and an assigned data protection. A
Storage Pool has a minimum of one drive. By default, your Iomega StorCenter ix12-300r has one Storage
Pool.
You can create either a data Storage Pool or a cache Storage Pool , which is a grouping of solid-state
drives that helps increase read and write performance to volumes in a date Storage Pool.
To Add a Data Storage Pool
1. On the Drive Management page, click Add Storage Pool.
2. In the Information section, enter a name for the Storage Pool.
3. To set the RAID protection, choose a value from the drop-down menu:
●
JBOD (None): Uses all of the storage space for data, providing contiguous storage space
spanning all member drives. Does not protect against data loss in the event of drive failure.
●
None (RAID 0): Uses all of the storage space for data. Does not protect against data loss in
the event of drive failure.
●
Mirror (RAID 1): Uses half of the storage space for protection, leaving half for actual data.
Protects data in the event of a single drive failure.
●
Mirror Stripe (RAID 10): Uses half of the storage space for protection, leaving half for actual
data. Protects data in the event of a single drive failure.
●
Parity (RAID 5): Uses the space corresponding to one drive-size for protection, leaving
remaining space for storing actual data.
●
Double Parity (RAID 6): Combines six or more drives in a way that protects data against
loss of any two drives.
4. Select the checkbox of the drive or drives you want to add to the Storage Pool. All drives in a
Storage Pool must be the same size.
5. Check Enable periodic consistency check to enable a monthly parity or mirror consistency
check.
6. If commonly used Shares, Backups, Documents, Movies, Music, Pictures, and SharedMedia do
not already exist on the ix12-300r device, check Create commonly used Shares to create these
Shares and add them to the Storage Pool. This option is not available if you are creating a cache
pool.
7. Check Use for SSD Cache to allow one or more solid-state drives (SSD) to be used as a cache
pool. You can only designate SSDs as cache pool drives if they have not already been assigned
to an existing Storage Pool. This cache pool becomes assigned to the Storage Pool you are
creating.
8. Click Create to add the new Storage Pool.
9. Click Cancel to discard any changes.
