Storage Pools

Describes what storage pools are.

The filesystem storage architecture consists of multiple storage pools that reside on each node in a cluster. A storage pool is made up of one or more disks grouped by the data-fabric file system. The default number of disks in a storage pool is three. The containers that hold the data-fabric filesystem data are stored in, and replicated among the storage pools in the cluster.

The following image represents disks grouped together to create storage pools that reside on a node:



Write operations within a storage pool are striped across disks to improve write performance. Stripe width and depth are configurable with the disksetup script. As the data-fabric filesystem performs data replication, you do not need to configure RAID.
