CBL-SAST-1261-100 Supermicro 50cm Cable

Enterprise Internal SlimSAS Fan-out Storage Interconnect featuring x8-to-dual x4 lane mapping with the CBL-SAST-1261-100

The CBL-SAST-1261-100 is a Supermicro internal SlimSAS fan-out cable assembly engineered for SAS/SATA backplane to HBA/RAID connectivity in dense rack server and storage platforms. By converting a SlimSAS x8 host connection into 2 SlimSAS x4 targets, the CBL-SAST-1261-100 preserves an 8-lane end-to-end topology while enabling clean segmentation across backplane ports for predictable drive enclosure mapping.

Designed for modern PCIe-attached storage controllers and SAS HBAs, the CBL-SAST-1261-100 supports scalable storage architectures where lane routing, controller port utilization, and chassis airflow constraints are equally critical. The 50cm length is optimized for internal chassis runs, reducing bend radius stress and helping maintain serviceability during component swaps, while keeping the interconnect aligned with enterprise cable-management practices and hot-swap backplane layouts.

Why Choose the CBL-SAST-1261-100?

The CBL-SAST-1261-100 delivers a practical density-to-performance advantage by consolidating an x8 host link into dual x4 backplane paths without introducing unnecessary adapters. For enterprise operations, the CBL-SAST-1261-100 supports consistent port mapping, easier fault isolation, and repeatable deployment across identical nodes, which improves scalability for clustered storage and virtualized environments.

Supermicro designs internal interconnects to match chassis and backplane mechanical tolerances, ensuring reliable retention, signal integrity, and long-term maintainability. As a designated spare/service part, this cable aligns with standardized data centre service workflows and supports consistent build configurations across fleets.

Key Applications:

• SAS/SATA backplane to HBA/RAID interconnect
• High-density rack server internal storage cabling
• All-flash and hybrid storage node wiring
• Chassis service and replacement cable kits
