Provisioning storage through aggregates
You can create an aggregate based on storage recommendations or manually depending on your requirement. You can create Flash Pool aggregates, SnapLock aggregates, and a FabricPool-enabled aggregates to provide storage for one or more volumes by using System Manager.
You must have enough spare disks to create an aggregate.
You cannot perform the following actions by using System Manager:
Combine disks of different sizes even if there are enough spare disks of different sizes.
You can initially create an aggregate with disks of the same size and then add disks of a different size later.
Combine disks with different checksum types.
You can initially create an aggregate with a single checksum type and add storage of a different checksum type later.
