Beyond Software RAID
Source: Dot Hill Systems
A Virtual RAID Adapter (VRA) is a unique and new class of pure, host-based software RAID solution. It combines the key advantages of pure software RAID with many of the key advantages of hardware RAID adapters. Unlike other host-based offerings, VRA solutions are not tied to any single vendor's disk I/O controller. This makes VRAs universally capable of working on most mainstream SATA or SAS I/O devices. The universal nature of VRA technology allows OEMs to easily migrate to new hardware platforms while maintaining their same look and feel and without having to change RAID vendors.
