VXI SCSI System Disk Modules

Product Summary

These SCSI disk modules are the mass storage system disk modules you need when space is at a premium and transportability is crucial. They connect to your host computer via the SCSI interface, not through the VXI backplane. This means controller communication with the disk wont interrupt--or be interrupted by--traffic on the VXI backplane.
