CBL-SAST-0847 Supermicro 76cm Cable

High-Density Internal Storage Interconnect Cable for x4 OCuLink Backplane Wiring with the CBL-SAST-0847

CBL-SAST-0847 is a Supermicro internal storage interconnect cable designed to preserve PCIe Gen4-class NVMe and SAS/SATA signaling integrity between an OCuLink (SFF-8611) x4 backplane and an HBA, RAID controller, or onboard storage controller. With a 1-to-1 OCuLink x4 to OCuLink x4 topology, CBL-SAST-0847 provides a predictable lane mapping that reduces integration risk in dense storage nodes where consistent port-to-bay alignment is mandatory.

In modern 1U/2U storage platforms, cable selection is a core part of the memory-to-storage data path design: improper routing can introduce stress, intermittent link training issues, or serviceability constraints. The 0.76 m length of CBL-SAST-0847 supports clean chassis routing to maintain airflow, minimize bend radius violations, and simplify maintenance access around PCIe expansion areas and backplane zones. This makes CBL-SAST-0847 well-suited for high-bay-count NVMe configurations, hybrid SAS backplanes, and internal PCIe/SAS cabling where sustained throughput and predictable enumeration are required.

Why Choose the CBL-SAST-0847?

CBL-SAST-0847 delivers an enterprise-aligned density-to-serviceability balance for storage servers by enabling reliable x4 lane connectivity without introducing adapters or mixed-connector points. For scale-out deployments, standardizing on CBL-SAST-0847 supports repeatable builds, faster swaps during field service, and consistent cabling patterns across controller generations and backplane revisions.

Supermicro engineers its interconnect accessories to match platform mechanical tolerances and data centre operational requirements, focusing on dependable fitment, stable signaling, and straightforward integration with validated storage chassis and backplane designs.

Key Applications:

• NVMe backplane to HBA interconnect
• SAS/SATA backplane to RAID controller cabling
