For example, if a drive fails, I/O to the failed drive continues as RAID Lite automatically regenerates data from parity on the other drives. You don't need to worry about being there to change a failed drive either. RAID Lite will automatically rebuild parity and data onto a standby drive. Then to close the window of vulnerability and complete the recovery process, RAID Lite supports "Hot Swapping" of disk drives, fans and power supplies. Each unit can be changed while the RAID Lite system is on-line.
