SCSI switches connect test points or devices to instruments for the testing, measuring, or monitoring industrial systems. Small computer system interface (SCSI) is an intelligent peripheral bus with a standard, device-independent protocol that allows many peripheral devices to be connected to the SCSI port. SCSI switches are often used in applications such as peripheral sharing between two hosts, clustered peripheral configurations, multiple peripheral cross-platform disaster recovery, and business continuity applications. SCSI switches are an excellent way to share expensive SCSI tape libraries and drives, RAID arrays, and peripherals such as printers and scanners. Redundant array of independent drives or disks (RAID) is a term for data storage schemes that divide or replicate data among multiple hard drives
