User Manual

Using the RAID GUI
2-29
Name Use the system default name as dgxldy. ‘x’ is the
DG identifier and ‘y’ is the LD identifier.
OR
Uncheck the ‘Use system default name’ box and
enter the name in the Name field. The maximum
name length is 63 bytes.
RAID Level Select a RAID level for the logical disk. Different
logical disks in a disk group can have different
RAID levels. However, when NRAID is selected,
there must be no non-NRAID logical disks in the
same disk group.
Capacity (MB) Enter an appropriate capacity for the logical disk.
This determines the number of sectors a logical
disk can provide for data storage.
Preferred
Controller
This option is only available when the redundant-
controller system is in use. Select the preferred
controller to be in charge of managing and
accessing the logical disk.
Stripe Size (KB) 4 / 8 / 16 / 32 / 64 / 128 / 256 / 512
The stripe size is only available for a logical disk
with a striping-based RAID level. It determines the
maximum length of continuous data to be placed
on a member disk. The stripe size must be larger
than or equal to the cache unit size.
Free Chunk Each free chunk has a unique identifier in a disk
group, which is determined automatically by the
controller when a free chunk is created. Select a
free chunk from the drop-down menu for logical
disk creation.
Initialization
Option
Noinit: No initialization process, and the logical disk
can be accessed immediately after it is created.
Regular: The controller initializes the logical disk by
writing zeros to all sectors on all member disks of
the logical disk. This ensures that all data in the
logical disks are scanned and erased.
Background: The controller starts a background
task to initialize the logical disk by synchronizing
the data stored on the member disks of the logical
disk. This option is only available for logical disks
with parity-based and mirroring-based RAID levels.
