SCSI Switches

Why use a SCSI Switch?


  • Share SCSI Devices between Multiple Hosts to maximise the peripheral investment.
  • Can be used to provide failover or failsafe protection when sharing SCSI RAID or Tape Libraries between an active host and a dormant host.
  • As a low cost alternative to a SAN
  • Use A SCSI Switch to extend the SCSI bus length beyond the 20 M limit
  • Complete hardware only solution- no software required.



  • Choose the number of Host SCSI channels, 2×1,3×1,4×1 etc
  • Choose the number of Target SCSI channels? if more than 1 (i.e. 2×2 ) then this is a Matrix Switch ? where any Host Channel can be connected to any Target Channel
  • Choose the SCSI bus type? LVD, HVD or SE SCSI, or a mixture of these busses in the Switch
  • Choose the method of controlling the Switch?Dynamic Switching, Manual control, control over the Network as a Network device, or Automatic Control via the SCSI bus itself or via a serial bus.
  • 160 Mbytes/sec Bandwidth
  • SCSI busses are totally isolated from each other, re-timed and regenerated, so that they can run the full length in either direction.
  • Each Bus segment is individually terminated. LVD busses have multi-mode termination
  • Bus Switching maintains correct termination, and only occurs at SCSI bus free
  • Suitable for HVD, LVD or SE SCSI, or a mixture of these
  • Rackmount or Desktop versions available
