JBOD, RAID 0/ 1/ 5/ 6 and single disk configurations are provided to offer the users the most complete options for data
protection. Hot spare is supported in RAID 5. When a hard drive fails, the system will start rebuilding data onto the hot spare
disk. There is no need to replace the failed drive immediately.
Online RAID Capacity Expansion and Online RAID Level Migration
With Online RAID Capacity Expansion, users can select to purchase the most cost-effective hard drives for initial server setup
and upgrade to larger ones in the future. All the stored data will be kept and seamlessly moved to the newly installed hard
