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. • The Expand/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. Changing target login parameters (Set Login Parameters) 1. Expand the View as drop-down box and select the iSCSI or Storage with iSCSI view. 2. Select Target > Set Login Parameters. 3. Enter the new values. Clearing the configuration (Clear Configuration) Use this option to reset the storage system to its original, unconfigured shipping configuration. Depending on the selected options, some or all of the configuration settings are changed back to the default values, including array, logical drive, target, initiator, and port information. 62 Configure

The

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
