1.2.5 Pool Disks

Exascale uses pool disks and storage pools to organize the physical storage provided by Exadata storage servers.

A pool disk is an Exascale-specific Exadata grid disk that reserves storage space for Exascale from an Exadata storage device.

Like any other Exadata grid disk, a pool disk is created by allocating space from an Exadata cell disk.

Based on its underlying physical characteristics, each pool disk is implicitly associated with a storage media type.
