Table 18 Target Deduplication/Compression Volumes Of Each Function - Fujitsu ETERNUS AF S3 Series Design Manual

2. Basic Functions
Operations Optimization (Deduplication/Compression and Storage Virtualization)
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.
