CBL-SAST-0631 Supermicro 55cm Cable

Enterprise MiniSAS HD to SATA Fanout Storage Cable Assembly with the CBL-SAST-0631

The CBL-SAST-0631 is a Supermicro internal MiniSAS HD (SFF-8643) to 4x SATA fanout cable assembly engineered to connect a host HBA or RAID controller to multiple SATA targets with consistent lane mapping and sideband support. In dense rack server storage builds, CBL-SAST-0631 enables a clean transition from a x4 MiniSAS HD host port to individual SATA drive connections, supporting predictable signal routing in chassis with limited service clearance.

Designed for modern server I/O topologies, CBL-SAST-0631 aligns with PCIe-attached storage controllers by providing the physical breakout required to attach SATA backplanes or direct-drive bays while preserving channel integrity across the full x4 lane path. The 0.55 m assembly with 4x 55 cm individual legs simplifies internal cable management, reduces strain on backplane headers, and supports repeatable airflow patterns—important when building systems around high-core-count CPU platforms, large memory footprints, and multiple PCIe expansion cards where thermal and serviceability constraints are tight.

Why Choose the CBL-SAST-0631?

CBL-SAST-0631 is selected for its deployment logic: reliable host-to-drive fanout with sideband capability for enterprise management workflows, straightforward integration with Supermicro storage chassis, and a density-friendly approach that keeps internal routing controlled as drive counts scale. CBL-SAST-0631 helps standardize spares and reduces mean time to repair by matching OEM platform expectations.

Supermicro designs cabling and interconnects with an emphasis on platform compatibility, predictable assembly tolerances, and long-term service continuity, supporting data centre operational standards where repeatable builds and validated replacement parts are required.

Key Applications:

• Internal SATA fanout from HBA/RAID controllers
• SATA backplane connectivity in rack servers
• OEM-compatible service and spare part replacement
• Storage expansion and rebuild standardization
