Traditional SCSI interfaces use a parallel interface. But there are other versions of SCSI available that connect via USB, Ethernet connectors, and Serial. SAS, or Serial Attached SCSI is becoming extremely popular and is starting to replace traditional SCSI connectors in many new computers and devices.

-- About SCSI --
Small Computer System Interface(SCSI, pronounced "skuzzy") is a way to tranfer data between computers and peripheral devices. SCSI is most commoly used for hard disks and tape drives, but it can be used with a wide range of devices include scanners and CD drives. SCSI connectors and devices are normally found in a commercial environment on used with computers such as servers. "SCSI is an intelligent, peripheral, buffered, peer to peer interface. It hides the complexity of physical format. Every device attaches to the SCSI bus in a similar manner. Up to 8 or 16 devices can be attached to a single bus. There can be any number of hosts and peripheral devices but there should be at least one host."Traditional SCSI interfaces use a parallel interface. But there are other versions of SCSI available that connect via USB, Ethernet connectors, and Serial. SAS, or Serial Attached SCSI is becoming extremely popular and is starting to replace traditional SCSI connectors in many new computers and devices.

- "In addition to many different hardware implementations, the SCSI standards also include an extensive set of command definitions. The SCSI command architecture was originally defined for parallel SCSI buses but has been carried forward with minimal change for use with iSCSI and serial SCSI."
- "In the modern SCSI transport protocols, there is an automated process of "discovery" of the IDs. SSA initiators "walk the loop" to determine what devices are there and then assign each one a 7-bit "hop-count" value."
