3. In the Split Pairs window of the Split Pairs wizard, complete the following and then click Finish:
• For Split Type, select the split type.
Values:
- Quick Split: Splits the new pair and then copies the data so that the S-VOL is immediately
available for read and write I/O. The XP7 storage system copies the remaining differential
data to the S-VOL in the background.
- Steady Split: Copies the differential data to the S-VOL and then splits the new pair.
Default: Quick Split
For more information about the methods you can use to split pairs, see “Pair splitting
methods” (page 49).
• For Copy Pace, select the rate at which you want the XP7 storage system to copy data.
Values:
- Slower: Improved host I/O performance but slower processing speed.
- Medium: Average processing speed and host I/O performance.
- Faster: Faster processing speed but slower host I/O performance.
Default: Medium
NOTE: Processing speed and host I/O performance are affected by the pace you select.
For more information about performance, see “Performance planning and calibrating
your XP7 storage system” (page 18).
