SCSI, or small computer system interface (pronounced 'scuzzy'), is a robust and widely accepted interface for storage and other computer peripheral devices. SCSI offers a variety of connector options and daisy-chaining capabilities.

Over the years, SCSI has evolved into a stable, fast parallel interface. The most recent innovaton, Ultra 320, has a throughput of up to 320MB/s.

Finisar's SCSI analysis product supports SCSI I through 320. The following is a summary of the SCSI bus specifications over the years.
