4.6.1.3 Capacity:

The maximum volume size is default in the first setting. Enter the appropriate volume

size to fit your application.

4.6.1.4 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".

No : It keeps the volume size with max. 2TB limitation.

64bit LBA: this option uses 16 byte CDB instead of 10byte. The maximum volume

capacity is up to 512TB. This option works on different OS which

supports 16byte CDB. Such as: Windows 2003 with SP1, Linux kernel

2.6.x or latter , FreeBSD 5.2.1 or latter

4K Block: it changes the sector size from default 512 to 4k. The maximum volume

capacity is up to 16TB. This option works under Windows platform only

and it CAN NOT be converted to Dynamic Disk, because 4k sector size is

not a standard format.

4.6.1.5 Initialization Mode:

This parameter 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.

4.6.1.6 Strip Size:

This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 10(1E),

5, 6, 50 or 60 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, 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

RAID level 3 can’t modify strip size.
