A. Function Specification List
Target Pool for Each Function/Volume List
*2 : An ODX Buffer volume is an exclusive volume that is required to perform ODX. Standard volumes, TPVs, or
FTVs can be used for the ODX Buffer volume.
*3 : A concatenated volumes cannot be created at the same time as a volume. Existing volumes can be con-
catenated by using LUN Concatenation.
*4 : If multiple volumes have been concatenated using the LUN Concatenation function, RAID Migration can
be executed only on concatenation source volumes.
*5 : Capacity expansion and RAID Migration cannot be performed at the same time.
*6 : The volume capacity can be expanded by specifying a relatively large capacity for the destination volume
when RAID Migration is performed.
*7 : The maximum number of concatenated volumes is 16.
*8 : If T10-DIF is enabled, this function cannot be executed.
*9 : Specify in units of FTRPs. FTVs that need balancing are automatically selected and balanced for each FTSP.
*10: A threshold can be set to the pool which includes the target volume.
*11: Encryption of Standard volumes and SDVs can be performed when the volumes are created, or after the
volumes have been created.
Encryption of SDPVs can be performed only when the volumes are created. SDPVs cannot be encrypted
after they are created.
Encryption of TPVs and FTVs is performed by creating a volume in the encrypted pool, or migrating a vol-
ume to an encrypted pool.
*12: Decryption of volumes is performed by specifying "Unencrypted" for the migration destination when mi-
grating the volumes.
*13: SDVs are used as the copy destination for SnapOPC/SnapOPC+. SDVs are also used as the copy source if the
copy destination of SnapOPC/SnapOPC+ is also set as the copy source (Cascade Copy/restore).
*14: This is part of the cache parameter settings, and cannot be configured in the units of volumes.
