Host-Side and Disk Array Parameters:
-
Host-Side Parameters -
Maximum Queued I/O Count:
This function allows you to configure the maximum number of I/O queue the controller
can accept from the host computer.
LUNs per Host SCSI ID: This determines how many LUN numbers
will be available with each host bus ID. The maximum number per ID is 32.
- Disk Array Parameters
-
Rebuild Priority: This determines how much system resources
is conducted when rebuilding a logical drive. The default setting of the rebuild
priority is “LOW.” Rebuild will have smaller impact on host I/O
access, but rebuild will take a longer time to complete. Changing the rebuild
priority to a higher level you will have a faster rebuild, but will certainly
increase the Host I/O response time. The default setting “LOW”
is recommended.
Write Verify on Normal Access: Errors may occur when a hard
drive writes data. To avoid the write
error, the controller can force hard drives to verify written data. This select
box lets the sybsystem perform Verify-after-Write during normal I/Os.
Write Verify on LD Rebuild: This select box lets the sybsystem
perform Verify-after-Write when rebuilding a logical drive.
Write Verify on LD Initialization: This select box lets the
sybsystem perform Verify-after-Write when initializing logical drives.
Maximum Drive Response
Timeout(ms): Select a maximum drive response timeout period.
