SFF-8087介绍

The SFF-8087 Mini-SAS connector is designed for implementing Mini SAS internal interconnect solutions.

The SFF-8087 is a 36-pin ‘Mini SAS‘ connector, and utilizes a plastic latching interface compatible with internal connections. Typical application would be a SAS link between a SAS HBA to a SAS drive subsystem.

The SFF-8087 is compliant with the latest 6Gb/s Mini-SAS 2.0 spec, and supports 6Gb/s data transfer protocol》

The SFF-8087’s Mini-SAS external counterpart is the SFF-8088 which is also Mini-SAS 2.0 compliant, and also supports 6Gb/s SAS data transfer speeds.

Both the SFF-8087 and the SFF-8088 can support up to 4-ports (4 lanes) of SAS data.

CS Electronics has incorporated the SFF-8087 connector onto both cable assemblies and pcb adapters.

The new generation HD Mini-SAS 3.0 SFF-8644 and SFF-8643 HD Mini-SAS connector interfaces have essentially replaced the SFF-8088 external and the SFF-8087 internal Mini-SAS interfaces, however CS Electronics continues to support our customer’s needs to preserve existing SAS architecture for older interface cables and adapters.

SFF规格说明

Many connectors’ solutions are developed and documented in the SFF Committee as SFF Specifications. Most are subsequently incorporated into standards or released as standards by organizations such as the EIA, ANSI, and IEC.

The following abridged list of SFF Specifications includes those referenced by the Serial Attach SCSI, Fibre Channel, Ethernet 802.3 and InfiniBand standards.
