RAID Level Migration

To migrate a logical drive is to do one or both of the following:

Change its RAID level

Increase the number of disk drives (sometimes called Expansion)

The FastTrak SX4300 and SX8300 RAID Controller cards support RAID Level Migration. However, you must use the WebPAM software to access this function. WebPAM ships with the FastTrak SX Series card on the software CD.

Migration takes place on an existing Functional logical drive without disturbing the existing data. While the logical drive is migrating, you can access the data as before. When migration is complete, your logical drive will have a different RAID level and/or a larger capacity.

Different types of logical drives use different organizational models and have varying benefits. The following outline breaks down the properties for each type of RAID supported by Promise products.
