2 Backup IPS ServeRAID Config; and
3 Restore/Convert Saved Config
These two options let you back up or restore the disk array configuration to
or from a diskette. This should be done when ever the configuration
changes (either manually by you, or automatically when a hot-spare is used
to replace a defunct drive).
Back up to Diskette!
We strongly recommend you back up your ServeRAID configuration to
diskette whenever a change is made.
The Restore/Convert option also helps you upgrade from a PCI RAID or
Streaming RAID adapter by converting your previous configuration.
Note: There are some limitations to this conversion option. See the
ServeRAID User′s Guide for more information.
4 Change Write Policy
Select Change write policy to configure a logical drive of an array to work in
either the write-through mode or the write-back mode. In the write-back
mode, the completion status is sent before the data is actually written to the
drives. Write-back mode generally provides higher performance with
increased risk of data loss in the event of power failure. In Write-through
mode completion status is sent after the data is written to the drives.
5 Change RAID Parameters
Change RAID Parameters allows you fine tune the RAID subsystem:
•
Stripe unit size - should be set to the size of I/O requests
•
Rebuild priority - specify which has higher priority: rebuild I/O or system
I/O
•
Auto rearrange - allows the adapter to resolve configuration related
conflicts automatically.
•
Read ahead - toggles the cache read ahead up to the end of stripe unit.
