The SFF-8644 is the latest HD MiniSAS connector design for implementing HD SAS External interconnect solutions.
The SFF-8644 is a 36-pin ‘High Density SAS’ connector, and utilizes a metal outer shell compatible with shielded external connections. Typical application would be a SAS link between a SAS HBA to a SAS drive subsystem.
The SFF-8644 is compliant with the latest SAS 3.0 spec, and supports 12Gb/s data transfer protocol
The SFF-8644’s HD MiniSAS internal counterpart is the SFF-8643 which is also SAS 3.0 compliant, and also supports 12Gb/s SAS data transfer speeds.
Both the SFF-8644 and the SFF-8643 can support up to 4-ports (4 lanes) of SAS data.
CS Electronics has incorporated this connector onto both cable assemblies and pcb adapters.
These newer SFF-8644 and SFF-8643 HD SAS connector interfaces have essentially replaced the older SFF-8088 external and the SFF-8087 internal SAS interfaces, however CS Electronics continues to support our customers’ needs for the older interface cables and adapters.
