HP E3249B VXI SCSI System Disk with DAT Drive

The HP E3249B is a C-size 2-slot VXI mass storage module that consists of a 4.29-Gbyte system disk and a 4-Gbyte (8 Gbytes with data compression) DAT drive. The single-ended SCSI-II connectors on the front panel provide the link to the host computer via a short external cable. Connection to other SCSI-II devices is achieved via the second SCSI-II connector. The SCSI-II interface does not provide a connection to the VXI backplane, assuring that the interface traffic will not interrupt, or be interrupted by, traffic on the VXI backplane. Typically, backup of 2 Gbytes takes approximately 30 minutes with compression and the industry standard Digital Data Storage (DDS) format.
