*1 : FTV operations can only be executed with ETERNUS SF Storage Cruiser.
FTRP balancing can be executed with either ETERNUS Web GUI or ETERNUS CLI.
*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 : Concatenated volumes cannot be created at the same time as a volume. Existing volumes can be concatenated by using LUN
Concatenation.
*4 : The volume capacity can be expanded by specifying a relatively large capacity for the destination volume when RAID Migration is
performed.
*5 : If multiple volumes have been concatenated using the LUN Concatenation function, RAID Migration can be executed only if the
concatenated volumes are set as the migration source volume.
*6 : Capacity expansion and RAID Migration cannot be performed at the same time.
*7 : The maximum number of concatenated volumes is 16.
The maximum capacity is 128TB (1TB for ODX Buffer volumes).
*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: Encryption of Standard volumes, SDVs, and WSVs 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 volume to an encrypted pool.
*11: The ODX Buffer volume is used as the file save destination for the former data created during the writing process of the copy source
volume when ODX is executed.
*12: This is part of the cache parameter settings, and cannot be configured in the units of volumes.
