Fujitsu ETERNUS DX100 S3 - Table 43 Management Functions for Deduplication;Compression Volumes

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 DX 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 in some cases.
● Operation of the Deduplication/Compression Volumes
The following table provides management functions for volumes related to Deduplication/
Compression.
