The maximum volume size is the default initial setting. Enter the appropriate volume size to fit
your application.

Greater Two TB Volume Support
If volume capacity will exceed 2TB, controller will show the "Greater Two TB Volume Support"
sub-menu. Greater Two TB Volume Support option: "No", "64bit LBA" and "4K Block".
o
No - It keeps the volume size with max. 2TB limitation.
o
64bit LBA - This option uses 16 bytes CDB instead of 10 bytes. The maximum volume
capacity up to 512TB. This option works on different OS which supports 16 bytes CDB.
Such as: Windows 2003 with SP1 or later, Linux kernel 2.6.x or later
o
4K Block - It changes the sector size from default 512 bytes to 4k bytes. The maximum
volume capacity is up to 16TB. This option works under Windows platform only, and it
cannot be converted to “Dynamic Disk”, because 4k sector size is not a standard format.
•
Initialization Mode
This option is used to define “Background Initialization”, “Foreground Initialization” or “No Init
(To Rescue Volume)”. When “Background Initialization”, the initialization proceeds as a
background task, the volume set is fully accessible for system reads and writes. The operating
system can instantly access to the newly created arrays without requiring a reboot and waiting
the initialization complete. When “Foreground Initialization”, the initialization proceeds must be
completed before the volume set ready for system accesses. There is no initialization happed
when you select “No Init” option. “No Init” is for customer to rescue volume without losing data
in the disk.
•
Stripe Size
This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 10, 5, 6, 50 or 60
logical drives. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB, 256KB,
512KB, or 1024KB. A larger stripe size produces better read performance, especially if your
computer does mostly sequential reads. However, if you are sure that your computer does
random reads more often, select a smaller stripe size.
Note:
o
RAID level 3 cannot modify the cache stripe size.
o
Roaming the stripe size 256K/512K/1024K RAID set to firmware version older than 1.52
will cause data corruption.
•
Cache Mode
The SAS RAID controller supports “Write Through” and “Write Back” cache.
