CBL-SAST-1259-100 Supermicro 60cm Cable

High-Density Internal Storage Breakout Connectivity for Rack Servers with the CBL-SAST-1259-100

The CBL-SAST-1259-100 is a Supermicro internal MiniSAS HD to SATA breakout assembly engineered for predictable SATA drive attachment from modern SAS HBAs or RAID controllers in 1U/2U platforms. By mapping a 4-lane SFF-8643 host interface to 4 independent SATA device links, the CBL-SAST-1259-100 supports clean backplane-to-drive routing where controller bandwidth and port topology must remain deterministic under sustained I/O.

In contemporary server architectures, storage expansion is frequently constrained by PCIe lane budgeting and controller port density rather than raw drive count. The CBL-SAST-1259-100 enables efficient fan-out from a single MiniSAS HD port, simplifying integration of SATA SSD and HDD tiers behind SAS controllers while keeping cabling within airflow and serviceability envelopes. With a 0.6m reach, the CBL-SAST-1259-100 is suited to chassis layouts requiring controlled bend radius, stable retention, and consistent signal paths between a backplane region and front drive bays.

Why Choose the CBL-SAST-1259-100?

Choosing the CBL-SAST-1259-100 standardises internal storage connectivity across mixed SATA/SAS deployments by aligning controller port structure to drive-level cabling without adapter stacks. It supports higher density per controller port, reduces routing complexity during scale-out builds, and improves maintainability for enterprise operations where rapid component replacement and consistent assembly practices are mandatory.

Supermicro designs storage interconnect components to match the mechanical constraints and reliability expectations of data centre platforms, prioritising fit, retention, and compatibility with validated chassis and backplane ecosystems. This approach supports repeatable integration and consistent service procedures across rack and storage nodes.

Key Applications:

• Rack server internal SATA drive connectivity
• SAS HBA or RAID controller port fan-out
• Backplane-to-drive bay cabling in 1U/2U chassis
• Hybrid SATA/SAS storage tier integration
