Description
The system type.
Values:
Open: BC or FS
Mainframe: BC Z, FC Z, or FCSE
Description
System options that you can enable or disable.
Values:
Swap & Freeze: Use this option to suppress the HP XP7 storage system's
update copy operations after a Quick Restore and the pair is in "DUPLEX"
status (for BC Z, FC Z, or FCSE) or "PAIR" status (for BC or FS). The S-VOL
(target volume for FC Z or FCSE) remains unchanged, and differential data
is not copied to the new S-VOL.
Default status: Disabled
HOST I/O Performance: Suppresses copy operations at all times regardless
of the workload. This system option increases I/O performance.
Default status: Disabled
Copy Pace: Maximizes host server I/O performance by suppressing copy
processing only if the pair status is "DUPLEX" (for BC Z, FC Z, or FCSE) or
"PAIR" (for BC or FS).
Processing-suppression/performance-improvement levels:
◦
(FC Z and FCSE only) FC Slower Copy1: Reduces background copying to
one half, thereby improving host I/O response.
◦
(FC Z and FCSE only) FC Slower Copy2: Reduces background copying to
one quarter, thereby improving host I/O response.
◦
(FC Z and FCSE only) 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, thereby improving the host I/O response.
