Volume Name:
The default Volume Set name will appear as “Volume---VOL#XXX”. You can rename the Volume
Set name provided it does not exceed the 16 character limit.
Raid Level:
Set the RAID level for the Volume Set. Click the down-arrow in the drop-down list. The available RAID
levels for the current Volume Set are displayed. Select the preferred RAID level.
RAID 6 strongly
recommended .
Capacity:
The maximum Volume Set size is displayed by default. If necessary, change the Volume Set size
appropriate for your application.
Greater Two TB Volume Support:
If the Volume Set size is over 2TB, an option “Greater Two TB Volume Support” will be automatically
provided in the screen as shown in the example above. There are three options to select: “No”, “64bit
LBA”, and “4K Block”).
No : Volume Set size is set to maximum 2TB limitation.
64bit LBA : Use this option for UNIX, Linux, and Windows Server 2003 + SP1 or later versions. The
maximum Volume Set size is up to 512TB.
4K Block : Use this option for Windows OS such as Windows 2000, 2003, or XP. The
maximum Volume Set size is 16TB. Just use the Volume as “Basic Disk”. Volume can’t be used
as “Dynamic Disk”; also can’t be used in 512Bytes block service program.
NOTE: For NAS system usage, if you want the maximum capacity allowed to be
over 2TB and to have a single Volume Set over 2TB, select the “64bit LBA” option.
Also, recommened to keep Volume Sets 16TB max for replication configurations.
Initialization Mode:
Set the Initialization Mode for the Volume Set. Foreground mode is completed faster, but the
Volume Set will not be accessible until initialization is completed. Background mode makes the Volume
Set available instantly, but the initialization process takes longer.
Stripe Size:
This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 10 (1E), 5 or 6
Volume Set. You can set the stripe size to 4KB, 8KB, 16KB, 32KB, 64KB, or 128KB. The default is
recommended for Volume Sets mapped to proNAS OS, internal RAID controller SAS Port 0.
Otherwise, Volume Sets mapped to SAS Port 1, for block device access, select stripe size that
matches the average file size that will be stored on the Volume Set (Host LUN).
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 small stripe size.
NOTE Stripe Size in RAID level 3 can’t be modified.
