## Summary description

Supermicro CBL-SAST-0957 is a 0.55 m Serial Attached SCSI (SAS) cable with SFF-8643 (mini SAS HD) on one end and SFF-8639 (U.2) on the other. Designed for connecting SAS controllers or backplanes to U.2 drives and adapters, it supports enterprise storage configurations and short-reach internal connections in servers and workstations.

## Long description

The Supermicro CBL-SAST-0957 is a 0.55 m internal SAS cable that connects a MiniSAS HD SFF-8643 port to a U.2 SFF-8639 drive interface. It is intended for short-reach internal connections inside servers and workstations and supports enterprise storage topologies where a direct MiniSAS HD to U.2 link with integrated power is required. The cable assembly includes a power lead to supply U.2 drives and is built to comply with industry SAS and SFF standards.
Advantages
This cable provides a compact and reliable connection between SFF-8643 controller ports and SFF-8639 U.2 drives, reducing cable clutter in dense server environments. Its short 0.55 m length is suitable for internal routing in rack servers and workstations, and the integrated power lead eliminates the need for a separate power adapter for the drive. The design follows established T10 and SFF specifications and is validated for use with Supermicro systems and compatible controller cards.
Suitable for
 Connecting MiniSAS HD controller ports to U.2 (SFF-8639) NVMe or SAS drives inside servers
 Short internal connections between backplanes and drive bays in rackmount or tower systems
 Upgrading or replacing internal storage cabling in enterprise storage arrays and workstations

How to use
Power down the system and follow standard electrostatic discharge precautions before installing the cable. Connect the SFF-8643 MiniSAS HD end to the SAS controller or backplane port, and insert the SFF-8639 U.2 connector into the drive or U.2 adapter. Route the power lead to the appropriate 4-pin power header and secure connections to avoid strain on the connectors. After installation, power on the system and verify drive detection in firmware or operating system storage utilities.
Usage recommendations
Use this cable for internal, short-reach connections only; avoid external routing or exposure to moisture. Maintain gentle bend radii and secure the cable with ties or clips to prevent movement and connector stress. Verify compatibility with your controller card or backplane and confirm that the drive power requirements match the provided power lead specifications before deployment.
