2. Enter the new values.

NOTE:

• The Cache Ratio determines the amount of memory allocated to read and write

operations. For improved performance, you may want to change this ratio to allocate

more memory to write operations, as high as 10% read/90% write.

•TheExpand/Rebuild Priority settings determine whether normal operations are

affected by an expansion or rebuild—changing these settings from the defaults may

affect system performance:

• A low priority has a minimal effect on normal operations, because the expansion

or rebuild process takes place only when the controller is not busy. However, there

is an increased risk of data loss if another physical drive fails before the process

is completed.

• A high priority has a greater effect on normal operations, because the expansion

or rebuild process has a higher priority than the normal operations. With more

system resources allocated to the expansion or rebuild process, the completion

time is reduced, also reducing the risk of data loss if another physical drive fails

before the process is completed.

• Before initiating an array expansion or logical drive extension, HP recommends

changing the corresponding priority setting to Medium or High.

including array, logical drive, target, initiator, and port information.
