PlatinumRAID Owner’s Manual
3.1.2 RAID Level
PlatinumRAID supports RAID level 0,1, 0+1 (10), 3 and 5.
3.1.3 Stripe Size
This parameter sets the size of the segment written to each disk in a RAID 0, 1, 3, or 5 logical
drive. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB. A larger
stripe size produces better-read performance for mostly sequential reads. For better random
reads performance, select a smaller stripe size.
3.1.4 Cache Mode
PlatinumRAID supports Write-Through and Write-Back Caching algorithms. In the Write-Back
caching method, modifications to data in the cache aren’t copied to the cache source until
absolutely necessary, whereas a Write-Through cache performs all write operations in parallel
-- data is written to the storage and
the cache memory simultaneously.
Write-back caching yields somewhat
better performance than write-through
caching because it reduces the number
of write operations to disk, but is also
more prone to data loss due to service
interruptions.
3.1.5 Volume Name
The default volume name will always
appear as Volume Set #. You can
rename the volume set name providing
it does not exceed 15 characters.
3.1.6 Tag Queuing
The Command Tag (Drive Channel)
function controls the command
tag queuing support for each drive
channel. Tag Queuing is useful for
enhancing overall system performance
under multi-tasking operating systems.
This function should normally remain
enabled unless instructed otherwise
by MicroNet support.
3.1.7 SCSI Channel (Reserved)
PlatinumRAID
supports
one
SCSI channel. Do not modify this
parameter.
3.1.8 SCSI ID
Each SCSI device on a SCSI device chain, including the host bus adapter,
must be assigned a unique SCSI ID number between 0-15.
