Copyback Process Time
The following table shows the time required for the copyback process.
Table 7 Copyback Process Time
RAID level Number of drives
Copyback process time (*1)
SSDs
RAID1 2 (1D+1M) Approx. 9 minutes/200GB
RAID1+0 4 (2D+2M) Approx. 5 minutes/200GB
RAID5 5 (4D+1P) Approx. 3 minutes/200GB
RAID5+0
8 ((3D+1P) ´
2)
Approx. 2 minutes/200GB
RAID6 6 (4D+2P) Approx. 3 minutes/200GB
*1: The value shows the copyback process time when the volume capacity is 200GB and there is no server I/O. The time that is required
depends on the type and configuration of the drive.
IMPORTANT
[Set RAID Group Parameter] specifies the rebuild priority for host access. When the Rebuild Priority is
"High", rebuild, copyback, and redundant copy performance can be improved.
Note that RAID group performance (throughput) may be reduced when a rebuild, copyback, or redundant
copy is being performed in the target RAID group.
