CBL-SAST-0856-1 Supermicro 74cm Cable

High-Density Internal Storage Breakout Cable Optimising Backplane Connectivity with the CBL-SAST-0856-1

The CBL-SAST-0856-1 is a Supermicro internal storage interconnect designed to bridge modern SlimSAS x8 host ports to dual MiniSAS HD backplane interfaces in dense rack servers. By providing an 8-lane breakout topology from 1x SlimSAS x8 (male) to 2x MiniSAS HD SFF-8643 (male), the CBL-SAST-0856-1 supports clean lane mapping for SAS/SATA signaling and, where the platform and backplane are wired accordingly, NVMe transport via compatible HBAs, RAID controllers, or PCIe-attached storage expanders.

In storage-centric CPU platforms where PCIe generation and lane budgeting determine I/O scalability, the CBL-SAST-0856-1 helps maintain predictable link routing between the controller and the backplane without consuming additional adapter slots. Its short-reach 74 cm chassis length is engineered for internal cable management in multi-bay enclosures, reducing airflow obstruction and simplifying service access to drive planes, while keeping the storage architecture aligned with high-availability requirements and consistent signal integrity across the 8 lanes.

Why Choose the CBL-SAST-0856-1?

The CBL-SAST-0856-1 is purpose-built for enterprise storage density, enabling a straightforward controller-to-backplane breakout that scales drive connectivity without adding intermediate conversion hardware. For systems engineers, the value is in repeatable integration: the CBL-SAST-0856-1 supports standardized internal SAS cabling practices, accelerates maintenance workflows, and fits deployment models where rapid node replacement and consistent cable topology are mandatory.

Supermicro designs interconnect components with a focus on platform-level compatibility and data centre serviceability, aligning cabling options to reference chassis layouts and validated storage backplanes. This engineering approach supports predictable builds and reduces integration risk in standardized fleets.

Key Applications:

• Internal backplane-to-HBA/RAID cabling
• High-density SAS/SATA drive shelves in rack servers
• Platform-qualified SlimSAS to MiniSAS HD breakout deployments
• Serviceable storage node integration and retrofits
