SAS Device to Mid-Plane Interconnects Roadmap

The MultiLink SASTM initiative's purpose is to improve how slot-oriented Solid State Drive (SSD) devices can be configured to improve I/O performance. The externally-accessible backplane slot-based drive architecture will be fully compatible for use with existing SAS/SATA storage devices as well as new devices designed to achieve higher performance.

A new form-factor compatible connector will extend SAS to a 4-port configuration. When running at 12Gb/s, a single slot will be capable of providing up to 96Gb/s of bandwidth (full duplex). Additional signals will be provided for general purpose use within the same connector. The MultiLink SASTM architecture is a slot-compatible implementation and will accommodate a variety of SSD form factors as well as existing hard disk drives (HDDs).

Minimizing the impact to protocol changes makes MultiLink SASTM primarily an enhancement to the existing connector. It was decided to maintain the existing Small Form Factor (SFF) slot dimensions for ease of refitting an existing system and for providing maximum system flexibility for storage OEMs.

SAS Device to Mid-Plane Interconnect Roadmap - August 2015.jpg


  • This roadmap shows connectors that enable SAS devices to plug directly into mid-plane connectors (no cable)
  • The connectors are grouped by standard dual-port SAS, 4-port SAS (MultiLink SASTM), and Multifunction (i.e, support for multiple interfaces, including 4-port SAS)
  • The port configurations (1 port, 2 ports, 4 ports) available for each connector are described, along with the maximum speed for each configuration

SAS Cabling Solutions Roadmaps

Serial Attached SCSI (SAS) burst upon the storage scene in 2004 as a serial replacement for the once ubiquitous parallel SCSI interconnect. While much attention is often given to the capabilities of the protocol and to the silicon and software required to implement these systems, it is often the physical interconnections that influence the adoption of I/O in a variety of market segments. Parallel SCSI, for example, supported everything necessary for clustered server deployments; however, the large unwieldy nature of the parallel cables and the restricted cabling distances greatly limited SCSI's applicability in these markets.

SAS removed many of these restrictions by opening up the bandwidth, improving cabling distances, and providing a compact connection scheme suitable for today's shrinking data center. While first generation solutions made tremendous strides forward, the connection schemes have continued to improve, opening up new markets for SAS in the process.

External Cabling Solutions

SAS External Cabling Solutions Roadmap - August 2015.jpg


  • This roadmap shows the external cable connectors for each generation of SAS, grouped by max cable length & type
  • "Active" copper cables contain circuitry that enhances signal quality, thus extending the length at which the cable will reliably operate
    • Cables not containing such circuitry are "passive"
  • SAS Connectivity Management refers to cables that support the Cable Management Interface (CMI)
    • CMI enables a host to determine the type and characteristics of an attached cable by communicating with logic within the cable assembly
      • Cables supporting CMI are "managed"
      • Cables not supporting CMI are "unmanaged"
      • See SFF-8636 document for details (
