CBL-0343L Supermicro 76cm Cable

Internal Storage Breakout Harness for Direct-Attach SATA Backplanes with the CBL-0343L

CBL-0343L is a Supermicro MiniSAS-to-SATA internal cable assembly engineered to map a 4-lane SFF-8087 host connection to 4 discrete SATA targets for direct-attach backplane connectivity from MiniSAS HBA/RAID adapters. By maintaining lane integrity across the breakout, CBL-0343L supports predictable port-to-drive enumeration during storage bring-up, reducing integration time in dense rack server chassis.

Designed for modern server storage architectures, CBL-0343L aligns with PCIe-attached storage controllers where the HBA/RAID card provides the compute-side interface while the cable provides the deterministic internal fan-out to a SATA backplane. The harness includes sideband-capable signaling support to preserve backplane management pathways required for enclosure monitoring and operational control. With an overall 0.76 m assembly and staggered leg lengths, CBL-0343L supports clean routing and strain-managed serviceability in multi-bay enclosures, helping maintain airflow paths and minimizing connector stress during maintenance cycles.

Why Choose the CBL-0343L?

CBL-0343L delivers a straightforward, enterprise-appropriate method to scale a single MiniSAS internal port into 4 SATA device links while retaining cabling discipline needed for reliable storage deployment. For IT teams standardizing chassis builds, CBL-0343L provides consistent connector mapping, supports dense storage population without ad-hoc adapters, and simplifies repeatable cabling plans across server SKUs.

Supermicro designs server interconnects to match chassis mechanical constraints and datacenter operational requirements, emphasizing fit, signal consistency, and long-term serviceability. This approach aligns with modern rack standards where predictable internal connectivity and maintainable routing are critical for uptime and efficient hardware lifecycle management.

Key Applications:

• Internal SATA backplane cabling
• MiniSAS HBA/RAID to SATA drive fan-out
• Storage bring-up and port mapping standardization
• Rack server chassis integration and retrofits
