===SCSI Parallel Interface===
Internal parallel SCSI cables are usually [[ribbon cables|ribbons]], with two or more 50–, 68–, or 80–pin connectors attached. External cables are typically shielded (but may not be), with 50– or 68–pin connectors at each end, depending upon the specific SCSI bus width supported. The 80–pin [[Single Connector Attachment]] (SCA) is typically used for hot-pluggable devices

===Fibre Channel===
[[Fibre Channel]] can be used to transport SCSI information units, as defined by the [[Fibre Channel Protocol]] for SCSI (FCP). These connections are hot-pluggable and are usually implemented with optical fiber.

===Serial attached SCSI===
[[Serial attached SCSI]] (SAS) uses a [[Serial Attached SCSI#Connectors|modified]] [[Serial ATA]] data and power cable.

===iSCSI===
[[iSCSI]] (Internet Small Computer System Interface) usually uses [[Ethernet]] connectors and cables as its physical transport, but can run over any physical transport capable of transporting [[Internet Protocol|IP]].

===SRP===
The [[SCSI RDMA Protocol]] (SRP) is a protocol that specifies how to transport SCSI commands over a reliable RDMA connection. This protocol can run over any RDMA-capable physical transport, e.g. [[InfiniBand]] or [[Ethernet]] when using [[RDMA over Converged Ethernet|RoCE]] or [[iWARP]].

===USB Attached SCSI===
[[USB Attached SCSI]] allows SCSI devices to use the [[Universal Serial Bus]].

===Automation/Drive Interface===
The Automation/Drive Interface − Transport Protocol (ADT) is used to connect removable media devices, such as tape drives, with the controllers of the libraries (automation devices) in which they are installed. The ADI standard specifies the use of [[RS-422]] for the physical connections. The second-generation ADT-2 standard defines iADT, use of the ADT protocol over IP (Internet Protocol) connections, such as over [[Ethernet]]. The Automation/Drive Interface − Commands standards (ADC, ADC-2, and ADC-3) define SCSI commands for these installations.
