Разъем 36 pin SFF-8643 Mini SAS HD socket
SAS is a serial, point-to-point interfce with SCSI protocol set. Typical application of SFF-8643 connector is a internal SAS link between a SAS HBA to SAS drives.

Some storage controllers may include SAS interface and NVMe  (PCIe) interface by multiplexing the data and sidebands signals. The pinout follows the SFF-9402 specificatons. 

The SFF-8643 interface is compliant with the SAS 3.0 specifications, supports 12Gb/s data transfer protocol and up to 4-ports (4 lanes) of SAS data.
