USB and eSATA to SATA II RAID Subsystem
User Manual
23
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.
