Caution
Note the following when using the Advanced Copy functions for Deduplication/Compression Volumes.
•
The CPU usage rate may increase depending on the EC/OPC priority setting. Be cautious of an I/O
performance reduction.
•
The copy performance may be significantly reduced when compared to non-Deduplication/
Compression Volumes (TPVs).
•
When using copies between ETERNUS AF storage systems, data without deduplication and
compression is sent to the copy destination. In addition, the bandwidth of the remote lines might
not be fully utilized.

*1:
Automatically created when the Deduplication/Compression function is enabled for TPPs.
*2:
Automatically deleted when the Deduplication/Compression function is disabled for TPPs.
*3:
Encryption can be performed by creating a volume in the encrypted pool, or migrating a volume to an encrypted pool.
