Logical Drive Migration
After a logical drive is created, some configurations can be modified using Migration Logical Drive function. You can assign a new RAID level, strip size and drive size for an existing logical drive.
RAID Level: There are number of different RAID levels, each level is a different way to spread data across multiple drives. Choose a right level depends on the application can be important to your system. For each RAID level definitions, please click here.
Each RAID level required a certain amount of hard disk drives. You need a minimum of two (2) drives to use RAID 1, three (3) drives for RAID 3 or 5 and four (4) drives for RAID 6. The RAID level drag down menu only shows available RAID levels according to the number of physical drives you selected.
Strip Size: Choose different strip size may affect the performance of RAID subsystem. Base on the applications user's should choose a best-fit stripe size to achieve the best data transfer rate. The following strip sizes are available: 16KB, 32KB, 64KB, 128KB, 256KB, 512KB, or 1024KB. A default stripe size is pre-selected.
Drive Size: In the Drive Size (MB) input box displays the maximum drive size per selected physical disk (total capacity of each disk.) Decreasing this value can create a smaller logical drive. The remainder can be used later by expanding the drive. Click here for Drive Expansion.
