AA-9072UWD: Ultra Wide, differential, 2 SCSI channels
AA-9073U2: Ultra2 Wide, 3 SCSI channels
Up to 8 logical drives, each with independent RAID modes
Up to 8 partitions per logical drive
Logical drive can be assigned a name for ease of identification
Number of drives for each logical drive has no limitation
Dynamic mapping of LUNs to logical drives. Two or more LUNs
can be mapped to the same logical drive for redundant host
operation
Concurrent/Background logical drive initialization
Performance optimization for Sequential or Random I/O
Allows multiple drive failure and concurrent multiple drive rebuild
of a RAID (0+1) logical drive
Configuration of individual SCSI target parameters
Controller can be assigned a name for ease of identification
Prior to first disk access, it allows adjustment of delay time during
controller initialization to enhance compatibility with slow-initial
drives
All channels are Ultra-Wide SCSI-2 (downward compatible to
SCSI-1) and can be configured as either a host or drive interface
Two or more SCSI channels can be simultaneously set as host
interface for redundant host system operation
Compatible and will automatically match any SCSI hard disks with
SCSI-1, SCSI-2 or (Ultra)-Wide-SCSI (1 or 2) specification
