Numerous physical disks are combined into a single, sizable storage pool. RAID groups are created by utilizing RAID technology to connect the disks in the storage pool. Multiple RAID groups may be present in storage pools.
storage pools provides following benefits:
You can allocate the storage space among many users and apps by creating multiple volumes in a storage pool.
One huge storage space can accommodate disks of various sizes and types.
A storage pool can be created by combining disks from connected expansion units with disks that are placed in the NAS.
While the storage pool is being used, additional disks can be added to increase storage capacity without causing service interruptions.
When a storage pool comprises a combination of SATA, SAS, and SSD drives, Qtier offers auto-tiering. Infrequently accessible cold data is automatically moved to slower disks by Qtier, while often accessed hot data is automatically moved to faster SSDs.
Storage pools can be used with snapshots. Snapshots capture the data's condition on a volume or LUN at a particular moment in time. If data is inadvertently altered or erased, it can then be recovered to that point in time.
A RAID 50 or RAID 60 storage pool can be created by stripping several RAID 5 or RAID 6 groups together using RAID 0.
