“Creating L1 and L2 pairs with different topologies” (page 40)
.
•
For Split Type, select how you want to split the pair.

If you are simultaneously creating an L1 pair and an L2 pair, to prevent a failure
and splitting the L2 pair before the pair is split (“PSUS” status), select Non Split.
- 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 Copy Pace, select the rate at which you want the XP7 storage system to copy data.
Values:
- Slower: Improved host server I/O performance but slower processing speed.
- Medium: Average processing speed and host server I/O performance.
- Faster: Faster processing speed but slower host server I/O performance.
Default: Medium
NOTE:
Processing speed and host server I/O performance are affected by the pace
you select.
