List of Target Pools and Volumes for Each Function

List of Target Pools and Volumes for Each Function
The following section shows the functions which can be performed on RAID groups, REC Disk Buffers, and pools.
The functions described in this section include functions that can be performed on RAID groups which comprise
REC Disk Buffers and pools.

*1: Only ETERNUS SF Storage Cruiser can perform operations on FTRP and FTSP.
*2: The maximum total number of TPPs and FTSPs.
*3: The number of TPPs for which the Deduplication/Compression function can be enabled is as follows:
ETERNUS AF250 S3: 4
•
ETERNUS AF650 S3: 8
•
*4: If an SDPV is created, an SDP is automatically created.
*5: If all of the SDPVs are deleted, SDPs are automatically deleted.
*6: When a volume exists in a pool, the pool cannot be deleted.
*7: If an FTRP is deleted, the FTSPs in that FTRP are also deleted. The FTRP needs to be deleted to delete the FTSP.
*8: This operation is possible in units of parent pools (FTRPs).
