USB and eSATA to SATA II RAID Subsystem

Installation and Configuration Manual
The RAID subsystem controller redistributes the original Volume Set over the original and newly added
disks, using the same RAID level configuration. The unused capacity on the expand Raid Set can then
be used to create an additional Volume Sets, with a different RAID level setting as needed by user.
1.3.3.4 Online RAID Level and Stripe Size Migration
User can do migration on both the RAID level and Stripe Size of an existing Volume Set while the
server is online and the Volume Set is in use. Online RAID level/stripe size migration can prove helpful
during performance tuning activities as well as in the event that additional physical disks are added to
the RAID subsystem. For example, in a system using two drives in RAID level 1, you could add capacity
and retain fault tolerance by adding one drive. With the addition of third disk, you have the option of
adding this disk to your existing RAID logical drive and migrating from RAID level 1 to 5. The result
would be parity fault tolerance and double the available capacity without taking the system off.
