Step 5.
After you create the arrays, click on Next.
The Logical Drive Definition screen displays. You can
use this screen to select the RAID level, stripe size, read policy,
cache policy, spanning option, and logical drive size.
Step 6.
Set the following options to define the logical drive:
a. Select the RAID level.
b.
The possible RAID levels for the logical drive display in the dropdown menu. Select the stripe size.
Figure 1.8
WebBIOS Logical Drive Definition Screen
The stripe size parameter specifies the size of the segment
written to each disk in a RAID configuration.
You can set the stripe size to 2, 4, 8, 16, 32, 64, or 128 Kbytes.
A larger stripe size produces higher read performance. If your
computer regularly performs random read requests, choose a
smaller stripe size. The default is 64 Kbytes.
c.
Select the read policy.
The read ahead parameter enables the read-ahead feature for
the logical drive. You can set this parameter to No Read
Configuring RAID Arrays and Logical Drives
Version 1.0
Copyright © 2003 by LSI Logic Corporation. All rights reserved.
1-15
Ahead, Read-ahead, or Adaptive. No Read Ahead is the
default setting. No Read Ahead specifies that the controller
does not use read-ahead for the current logical drive. Readahead specifies that the controller uses read-ahead for the
current logical drive. Adaptive specifies that the controller
begins using read-ahead if the two most recent disk accesses
occurred in sequential sectors.
d. Select the write policy.
You can set the write policy to Write Back or Write Thru.
The default setting is Write Thru caching. In Write Back
caching, the controller sends a data transfer completion signal to
the host when the controller cache receives all the data in a
transaction. In Write Thru caching, the controller sends a data
transfer completion signal to the host after the disk subsystem
receives all the data in a transaction. Write Thru caching has
a data security advantage over write-back caching. Write Back
caching has a performance advantage over Write Thru
caching.
Caution:
Do not use write back caching for any logical drive in a
Novell NetWare volume.
e. Select the cache policy.
The cache policy applies to reads on a specific logical drive. The
default is Direct I/O. It does not affect the read ahead cache.
The options are Cached I/O or Direct I/O. Cached I/O
buffers all reads in cache memory and is the default setting.
Direct I/O does not buffer reads in cache memory. Direct
I/O does not override the cache policy settings. Direct I/O
transfers data to cache and the host concurrently. If the same
data block is read again, the host reads it from cache memory.
f.
Configure the spanning mode.
Enable or disable the spanning mode for the current logical
drive. If spanning is enabled, the logical drive can occupy space
in more than one array. If spanning is disabled, the logical drive
can occupy space in only one array.
To span arrays, the arrays must have the same stripe width and
must be consecutively numbered. If these criteria are not met,
CU ignores the span setting.

h. Click on the Accept button to accept the changes or click on the
Reset button to delete the changes and return to the previous
settings.
