Attached storage disks are grouped together into a storage pool, which combines and abstracts the aggregate disk storage into a single contiguous space from which volumes can be thinly provisioned. SnapCLOUD currently supports only a single storage pool, and all attached storage disks are added to the pool when incorporated into the server. After a disk has been incorporated into a storage pool, it cannot be removed without destroying the storage pool and potentially losing data.
Disks can only be attached to a VM in the Azure portal one at a time, but once attached they can be incorporated to a storage pool in the SnapCLOUD web UI individually or in groups. Disks of any size can be incorporated into the same storage pool without wasting space on mismatched drive sizes as long as the disks are incorporated individually or in groups of like-sized drives. For best performance, incorporate multiple like-sized disks in the same operation to cause data to be striped across the new disks.
