3.5.3.2Logical 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.

|
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. |

3.5.3.3Easy 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:
Step 1. Select Configuration→ Easy Configuration at the main menu.
The Configuration Menu screen displays, as shown in Figure 3.1.
