Serial ATA Flash Drive AP-SRFD255AXXXXR-G 2.6 Virtualization Virtualization is a mechanism, where the HBA can have an alternate view of the physical drives. 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

Serial ATA Flash Drive AP-SRFD255AXXXXR-G The RAID Processor supports a definition of Safe (RAID-1) set. 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. The two physical partitions used for mirroring must
