• Swap & Freeze: Quick Restores and then immediately saves the data.
Note: Enabling this option with Quick Restore inhibits the update copy
operation and the paired S-VOL is not updated.
• Host I/O Performance: Gives weight to I/O response rather than the copy
time. This option controls the copy operation and improves the host I/O
response.
• Copy Pace Ext. Slower1
• Copy Pace Ext. Slower2
• Copy Pace Ext. None
Reducing the copy volume in “PAIR” status curbs the influence to the I/O

Copy Pace Ext. None determines the host server’s I/O performance.
