Shares reside on volumes, which along with iSCSI volumes, reside in Storage Pools. Volumes allow you to partition space in Storage Pools, and Storage Pools group multiple physical drives together into a single logical unit to provide redundancy, availability and capacity. All the drives in a Storage Pool must be the same size and should have the same protection (for example, RAID 1 RAID 5).
All disks within a single Storage Pool must meet the following requirements:
●Same manufacturer
●Same rotational speed
●Same capacity
Mixed disk configurations may result in unpredictable device behavior and will not be supported. If you need technical assistance, please be prepared to backup your data and remove any unsupported drives or configurations.
Storage Pools
A Storage Pool is a grouping of drives with a certain storage size and an assigned data protection. A Storage Pool has a minimum of one drive. By default, your
Storage Pool Data Protection
For each Storage Pool, you can select its type of protection. Protection type determines how data is replicated across a Storage Pool and determines the amount of space used for data protection and storage. The drives in your
For more information on selecting RAID types, refer to Changing RAID Protection Types.
Volumes
A Volume is a single storage area. A volume can be comprised of one or more hard drives. In a single- volume system, the volume consists of the entire storage space. Shares reside in volumes. iSCSI drives also reside in volumes.
