Advanced Configuration (Step 2 - Logical Drive Creation)
Alias Alias (any value)
RAID level Indicates the available RAID level depending on the number of
physical drives selected in the previous screen.
RAID0 for a single physical drive
RAID0 or RAID1 for two physical drives
RAID0 or RAID5 for three physical drives
RAID0, RAID5 or RAID10 for four physical drives
Capacity Specify the capacity of a logical drive to be created. The maximum
permissible capacity is shown to the right of [Max:].
Strip Block Size Indicates the block size of a logical drive. The default is 64KB.
Sector Indicates the sector size. The default is 512 bytes.
Read Policy Set read policy.
Read Cache: Uses cache in reading.
Read Ahead: Uses cache in reading and further provides previous
reading. Previous reading before request can improve the system
performance (default).
No Cache: Does not use cache in reading.
Write Policy Set write policy.
Write Through: Does not use cache in writing.
Write Back: Always uses cache in writing. It is expected that this
setting can improve writing performance.
However, in spite of the setting, the actual write cache state may
change depending on the write cache setting of the controller
(Adaptive Writeback Cache) and the battery state.
Initialization Set whether logical drives are initialized just after they are created.
None: Does not initialize logical drives (default).
Quick: Initializes master boot sectors only.
Full: Initializes all logical drives.
In RAID0, only "None" or "Quick" is selectable.
4. After the selections, click [Update].
The logical drive is added and displayed graphically in Capacity Usage. If some capacity
remains in [Max:] of the Capacity field, clicking the Update button allows another logical drive
to be added. The above configuration can be unique to each logical drive.
5. After required logical drives are added completely, click [Next].
