3.5.3.2 Logical Drive Parameters
For the logical drive you can change the RAID level and stripe size. Table 3 .3
contains descriptions of the logical drive parameters.
3.5.3.3 Easy Configuration
In Easy Configuration, the CU associates each hard drive with a single logical
drive. If logical drives have already been configured, the CU does not change
their configuration. Perform the following steps to create arrays using Easy
Configuration:
Step1. Select Configuration→ Easy Configuration at the main menu.
The Configuration Menu screen displays, as shown in Figure 3.1.
Table3.3 Logical Drive Parameters and Descriptions
Parameter Description
RAID Level The number of physical drives in a specific array determines the RAID
levels that can be implemented with the array.
RAID 0 requires one or two physical drives.
RAID 1 requires exactly two physical drives.
RAID 10 requires exactly four physical drives.
Stripe Size 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 4, 8, 16, 32,
64, or 128 Kbytes. The default is 64 Kbytes.
A larger stripe size produces higher read performance. If your computer
regularly performs random read requests, choose a smaller stripe size.
