Storage pools are used to classify storage using user-defined criteria. The best practice is to group disks with similar characteristics into a storage pool. A single storage pool can contain both SSD and HDD storage.
To create a storage pool
Prerequisites:
Disks must be initialized and discovered by the cluster before you can add them to a storage pool.
Add the selected disks to an existing pool or specify a new storage pool.
If a disk already belongs to a pool, you cannot add it to a new pool. However, you can move it to another existing pool.
If you select an existing pool, the Storage Pool Capacity shows the existing capacity for the selected pool.
