This table is displayed when the System Type is Mainframe.

DescriptionItem

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
