Storage Pool Management

Understanding How Your Content Is Stored

Content on your Iomega StorCenter is stored in Shares. To access content in Shares, your client
computer uses protocols, such as AFP and Windows File Sharing. Block-level data is stored in iSCSI
drives. File systems maintain the physical location of content that resides in Shares. File systems in
turn reside on volumes. iSCSI drives reside on volumes. Volumes allow you to partition space in
Storage Pools, and you can use that space for file systems. Space in Storage Pools is also available
for iSCSI drives. Storage Pools group physical drives together. All the drives in a Storage Pool should
be the same size and all have the same protection, such as RAID 5.

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 device has one Storage Pool.
Storage Pool Data Protection
For each Storage Pool, you can select its type of protection. Protection type determines how data is
replicated across a Storage Pool and determines the amount of space used for data protection and
storage. The drives in your Iomega device are protected using a built-in, pre-configured technology
that redundantly stores data across the drives, so that if a single drive fails, in most cases, you will
not lose any data. This technology, known as RAID (Redundant Array of Independent Disks), enables
a series of drives to act together as a single storage system. If you create multiple Storage Pools,
you can assign different
For more information on selecting RAID types, refer to

Volumes

A Volume is a single storage area. A volume can be comprised of one or more hard drives. In a
single-volume system, the volume consists of the entire storage space. Shares reside in volumes.
iSCSI drives also reside in volumes.
