SAS cable Supermicro CBL-SAST-1276F-100 — 0.76 m, Slimline x8 to 2× Slimline x4, black

The Supermicro CBL-SAST-1276F-100 is a 0.76 m internal SAS cable with a Slimline x8 connector on one end and two Slimline x4 connectors on the other. It is engineered for server and storage systems to provide high-speed Serial Attached SCSI links between controllers, backplanes and drives. The compact Slimline connectors and black outer jacket make the cable suitable for constrained rack environments and internal cable routing while maintaining signal integrity for SAS data transfers.

Advantages

The short 0.76 m length reduces excess cabling in dense server bays and improves airflow compared with longer cables. Slimline x8 to dual Slimline x4 connectivity enables a single controller port to connect to two downstream devices or backplane channels without additional adapters. The unified black jacket and compact profile support neat cable management and internal routing inside chassis with limited space. The cable is intended to meet typical SAS interconnect electrical and mechanical expectations for reliable data transfer in enterprise environments.

Suitable for

• Connecting a Slimline x8 SAS host or controller port to two Slimline x4 device ports or backplane channels
• Internal cabling in 1U–4U rack servers and storage enclosures with limited depth
• Replacing or consolidating short internal SAS runs to improve airflow and tidiness

Key specifications

• Cable length: 0.76 m
• Connector type (end A): Slimline x8
• Connector type (end B): 2 × Slimline x4
• Colour: black

How to use

Install the cable by aligning the Slimline connector keyed surfaces with the corresponding ports on the controller, backplane or drive, then apply firm, even pressure until the connector seats. Route the cable to avoid sharp bends and to maintain recommended bend radius for high-speed signal integrity. Use existing chassis tie points or cable management clips to secure the cable and prevent strain on connectors. Verify device recognition and link status in system firmware or the operating system after powering on.

Recommendations

For reliable operation, avoid excessive bending near connector heads and keep the cable length appropriate for the internal layout to reduce signal loss. When connecting multiple devices, confirm compatibility of Slimline connector pinouts and SAS topology in the server or storage documentation before deployment.
