1.2.3 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 a portion of an Exadata storage device (HDD or flash device) for use by Exascale. Like any other Exadata grid disk, a pool disk is created by allocating space from an Exadata cell disk.
