WEB BROWSER-BASED CONFIGURATION
• Greater Two TB Volume Support
Controller uses the "Greater Two TB Volume Support" sub-
menu to set the volume capacity and sector size. Greater Two
TB Volume Support option: "No", "64bit LBA" and "Use 4K
Block".
- No
When this option is enabled, it keeps the volume size with
max. 2TB limitation. For any hard disk drives working in the
4K native mode in the Raid set, the volume set directly sets
and exposes 4KB sector size to the operating system.
- 64bit LBA
This option uses 16 bytes CDB instead of 10 bytes. The
maximum volume capacity up to 512TB. For any hard disk
drives working in the 4K native mode in the Raid set, the
volume set directly sets and exposes 4KB sector size to the
operating system.
This option works on different OS which supports 16 bytes
CDB.
- Use 4K Block
This option uses 16 bytes CDB and changes the sector size
from default 512 bytes to 4k bytes. Windows XP only sup-
ports maximum volume capacity is up to 16TB.
• 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 sys-
tem reads and writes. The operating system can instantly ac-
cess to the newly created arrays without requiring a reboot
and waiting the initialization complete. When “Foreground Ini-
tialization”, 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.
