CBL-SAST-0623 Supermicro 45cm Cable

High-Density Internal SAS Interconnect Cabling for Backplane-to-Controller Links with the CBL-SAST-0623

The CBL-SAST-0623 is a Supermicro internal MiniSAS HD (SFF-8643) to MiniSAS HD (SFF-8643) 4-lane cable engineered to connect a SAS/SATA backplane directly to an HBA or RAID controller within enterprise server and storage chassis. In modern platforms where CPU and GPU resources depend on consistent storage I/O, the integrity of the internal SAS link is a primary architectural dependency for predictable latency and sustained throughput.

By providing a 1x-to-1x SFF-8643 path, the CBL-SAST-0623 supports clean PCIe-attached storage topologies where the controller’s PCIe generation and lane budgeting are preserved for compute and networking, while the backplane interconnect remains electrically stable. The 45cm assembly length is optimized for typical rack server and JBOD internal routing, supporting serviceability without excessive slack that can disrupt airflow, obstruct fan walls, or complicate hot-swap bay maintenance. The CBL-SAST-0623 is aligned for SAS/SATA backplane connectivity in Supermicro and compatible chassis where repeatable builds and fast part replacement are operational requirements.

Why Choose the CBL-SAST-0623?

The CBL-SAST-0623 delivers a dependable 4-lane internal SAS interconnect that helps maintain storage domain reliability at scale, especially in dense configurations where backplane-to-controller cabling must be consistent across nodes. It is well suited for standardized deployment images, spare-part stocking, and rapid return-to-service workflows where cable fit and connector mating are non-negotiable.

Supermicro designs internal interconnect accessories to match chassis mechanical tolerances and data centre service models, emphasizing compatibility, repeatability, and long-term availability. RoHS and REACH compliance supports enterprise governance requirements for regulated procurement and lifecycle management.

Key Applications:

• SAS/SATA backplane to HBA connectivity
• RAID controller to internal drive backplane links
• Server and JBOD maintenance spare inventory
• Storage node standardization in clustered deployments
