USER MANUAL
Rebuild Setting
Check the respective boxes to enable these features:
Disable Hot Spare/Auto Rebuild
- Disables automatic rebuilding using a hot spare drive or a
newly installed replacement drive. With this option checked, you must initiate rebuilding
manually. See RAID 1 (Mirroring) and Hot Spare Drive.
Rebuild/Sync Rate
- Allocates system resources between rebuilding the array and responding
to read/write commands from the computer system.
A
High
setting assigns most of the system resources to a rebuild or synchronization of the
array. The process will finished sooner but read/write requests are handled slower.
A
Low
setting assigns most of the system resources to handling read/write requests. Read/
write requests are handled at nearly normal speed while the rebuild or synchronization takes
longer.
See Rebuild an Array for more information on the rebuilding process.
Array Cache Settings
Click on the Array View
icon and look in the Information View to see the Array Cache
Setting.
Enable Driver Write Cache
must be checked in Disk Parameters (see above) for this option to
work.
Click on the dropdown menu to select the
Cache Setting
.
Write Through
- Data is written to the cache and hard drive at the same time. This
arrangement is safer.
Write Back
- Data is written to the cache first and to the hard drive later. This arrangement
increases performance at the risk of data loss if the power fails.
