CBL-SAST-0556 Supermicro 90cm Cable

High-Density Internal Storage Breakout Connectivity with the CBL-SAST-0556 MiniSAS HD to SATA Fan-Out Cable

The CBL-SAST-0556 is a Supermicro internal storage breakout cable designed to bridge a 4-lane MiniSAS HD (SFF-8643) host interface to multiple SATA endpoints for consistent chassis-level storage integration. In server platforms where the CPU and chipset expose storage through SAS/SATA HBAs or RAID controllers, the CBL-SAST-0556 provides a deterministic physical layer for attaching SATA drive bays or SATA backplane ports without compromising serviceability.

By mapping the MiniSAS HD lanes to 4x SATA male fan-out connectors, the CBL-SAST-0556 supports scalable drive population and predictable signal routing in dense 1U/2U storage nodes. The integrated sideband capability enables enclosure and management signaling paths commonly required for enterprise backplane implementations. With a 0.9m overall length and staggered leg lengths to reduce bend stress and connector crowding, the CBL-SAST-0556 helps maintain airflow-aware cable dressing, minimizes strain on headers, and supports clean PCIe card-to-backplane routing in systems with constrained internal clearance.

Why Choose the CBL-SAST-0556?

The CBL-SAST-0556 delivers a practical density-to-performance balance for SATA storage expansion from a single MiniSAS HD port, keeping internal cabling controlled as drive counts scale. It is engineered for repeatable deployment in production racks, simplifying maintenance windows, reducing miswires during field service, and supporting consistent backplane connectivity practices across server and storage fleets.

Supermicro designs interconnects with a platform-first engineering approach, aligning pinouts, retention, and routing expectations with modern data centre chassis layouts. This focus on interoperability and mechanical reliability supports long-term lifecycle management in standardised enterprise builds.

Key Applications:

• SATA drive bay to HBA/RAID controller connectivity
• Internal storage backplane cabling in 1U/2U servers
• High-density storage nodes and JBOD-style chassis wiring
• Service-ready replacement and standardisation builds
