The RAID  Processor allows various access strategies to the connected Hard Disks and may be configured to represent  n-drives as m-drives to the user. This provides the user with a simple way of partitioning storage resources  according to use. For example, the processor could represent one driv

The HBA (Host Bus Adapter) does not need  to know anything about the physical arrangement of the data. To the HBA, the virtualized drive behind RAID  Processor is a normal drive that just happens to be safer (fault tolerant). All error handling and Data rebuild is  managed by the RAID Processor.
