Fujitsu ETERNUS DX100 S3 - Table 41 Volumes that Are to be Created Depending on the Selection of Deduplication and Com- Pression; Table 42 Deduplication;Compression Setting for Tpps Where the Target Volumes Can be Created

Deduplication is performed for Deduplication/Compression Volumes within the same TPP. Dedu-
plication is not performed for data in different TPPs. In some cases, deduplication might not be
performed even within the same TPP.
To enable the Deduplication/Compression function for existing volumes, use the RAID Migration
function.
Volumes that are to be created and the Deduplication/Compression setting for TPPs where the tar-
get volumes can be created vary depending on the selection of "Deduplication" and "Compres-
sion".

TPPs with the Deduplication/Compression function enabled have one of the following attributes:
deduplication/compression, deduplication only, or compression only. The Deduplication/
Compression Volume conforms to the attribute of the TPP where the volume is created. TPVs
where the Deduplication/Compression function is enabled and disabled can exist together within
each TPP.
● Deduplication/Compression System Volumes
The following internal volumes are created for each TPP where the Deduplication/Compression
function is enabled.
