CBL-SAST-0759 Supermicro 15cm Cable

High-Density Internal Storage Breakout Cable enabling 4-Port SATA fan-out with the CBL-SAST-0759

The CBL-SAST-0759 is a short-run internal storage harness designed to translate a single MiniSAS HD (SFF-8643) host port into 4 discrete SATA device connections inside modern rack servers. In SAS/SATA backplane architectures, this breakout approach preserves orderly lane mapping across 4 independent channels while maintaining a clean signal path for dense chassis layouts.

Using a 4-lane link topology with sideband support, the CBL-SAST-0759 aligns with server platforms where PCIe-attached HBAs or RAID controllers present MiniSAS HD internal ports and the storage plane terminates on individual SATA drives or SATA backplane headers. The 15cm length is optimized for tight routing between controller, midplane, and drive bay zones, reducing slack that can obstruct airflow or interfere with service access. This makes the CBL-SAST-0759 suitable for capacity-focused nodes, boot-drive harnessing, or multi-bay SATA expansions where predictable internal cabling is essential to platform reliability.

Why Choose the CBL-SAST-0759?

The CBL-SAST-0759 delivers a disciplined cabling strategy for high-density servers by consolidating 4 SATA connections into a single MiniSAS HD endpoint, simplifying installation while maintaining enterprise-grade signal integrity expectations. For systems engineers, the value is in repeatable lane breakout, sideband-aware integration, and a form factor that supports consistent serviceability across scalable chassis deployments.

Supermicro designs internal interconnects to match the mechanical and electrical constraints of its server and storage platforms, emphasizing dependable fitment, stable connectivity under vibration, and compatibility with contemporary data center compliance requirements such as RoHS and REACH.

Key Applications:

• Internal SATA drive connectivity from MiniSAS HD controllers
• 4-port SATA fan-out for backplane or direct-drive bays
• Short-run cabling in high-density rack servers
• Boot or cache drive harnessing in multi-bay chassis
