CBL-SAST-1149-85 Supermicro 49cm Cable

High-Density Internal PCIe/SAS Breakout Harness for NVMe Backplanes with the CBL-SAST-1149-85

CBL-SAST-1149-85 is a Supermicro internal server/storage interconnect cable designed to route 8 PCIe/SAS lanes from a single SlimSAS x8 (SFF-8654) host connection to dual OCuLink x4 (SFF-8611) endpoints for NVMe backplane and device-side connectivity. In modern PCIe-centric storage architectures, this breakout topology enables clean segmentation into two independent x4 links, aligning with common U.2/U.3 NVMe wiring patterns and controller port groupings on motherboards, RAID adapters, or HBAs.

Engineered for dense 1U/2U platforms, CBL-SAST-1149-85 uses a right-angled SlimSAS connector to preserve clearance at the chassis edge and backplane interface, helping maintain serviceability and consistent cable routing under constrained airflow paths. The 49 cm length supports structured cable management between midplane/backplane zones and riser or onboard connectivity, reducing strain on internal headers and lowering the risk of intermittent link behavior during maintenance cycles. All connectors are male, simplifying standardized internal harness planning across storage nodes.

Why Choose the CBL-SAST-1149-85?

CBL-SAST-1149-85 provides a predictable lane-mapping approach for scaling NVMe density without redesigning the platform’s internal topology. By breaking 8 lanes into two discrete x4 paths, CBL-SAST-1149-85 supports straightforward attachment to dual OCuLink targets while maintaining enterprise expectations for repeatable integration, minimized obstruction, and reliable internal signal routing in high-port-count storage servers.

Supermicro designs interconnect components to match system-level mechanical constraints and data centre deployment standards, emphasizing consistent connector fit, dependable assembly quality, and compatibility with validated server and storage backplanes to reduce integration variability across fleet rollouts.

Key Applications:

• NVMe U.2/U.3 backplane-to-host cabling
• OCuLink x4 internal PCIe expansion wiring
• High-density 1U/2U storage server harnessing
