BC Z/FC Z/FCSE System Options table
This table is displayed when the System Type is Mainframe.
Description Item
The system options include: System Option
• Swap & Freeze: Use this option when you want to save data immediately after Quick
Restore as-is. When you enable this option and execute Quick Restore, update copying
after Quick Restore is inhibited, the secondary volume in the DUPLEX status is saved
without being updated.
•
Host I/O Performance: Use this option when you give higher priority on I/O response
than volume copy time. Enabling this option inhibits execution of copy processing, thereby
improving host I/O response.
•
FC Slower Copy1: Reduces background copying to one half, thereby improving host I/O
response.
• FC Slower Copy2: Reduces background copying to one quarter, thereby improving the
host I/O response.
•
FC Ext. Slower Copy1: When the MP operating ratio of the MP blade to which the source
volume or target volume in a Compatible FlashCopy relationship is allocated exceeds
65%, background copy operations are suppressed, and consequently host I/O response
improves.
•
FC Ext. Slower Copy2: When the MP operating ratio of the MP blade to which the source
volume or target volume in a Compatible FlashCopy relationship is allocated exceeds
50%, background copy operations are suppressed, and consequently host I/O response
improves.
