The table below shows the differences between Volume Groups and Dynamic disk pools in E-Series storage:
|Dynamic Disk Pools
|RAID 6 only
|128 KB fixed
|Disk Drawer loss protection
|Disk Selection for volume creation
|High, Cannot be edited
|Suited IO type
Note: Hot spares are not required for disk pools. For disk pools, a certain amount of capacity is preserved for emergencies like drive failures. The maximum disk preservation is 10 disks (equivalent capacity is reserved in each drive in the pool).
