CBL-SAST-1253-100 Supermicro 53cm Cable

High-Density Internal SAS/PCIe Storage Breakout Cabling for NVMe and SAS Backplanes with the CBL-SAST-1253-100

The CBL-SAST-1253-100 is a Supermicro SlimSAS internal breakout interconnect designed to route 8 lanes of SAS/PCIe connectivity from a single SlimSAS x8 host port to 2 SlimSAS x4 device/backplane ports. In modern CPU platforms where PCIe expansion is allocated directly to storage controllers and NVMe backplanes, this topology supports clean lane mapping without unnecessary adapters, helping preserve signal integrity and predictable enumeration.

Optimised for dense storage servers, the CBL-SAST-1253-100 enables serviceable internal wiring between an HBA/RAID controller or PCIe/NVMe switch domain and dual x4 backplane endpoints. Its Left-Exit to Straight routing is suited to constrained chassis cable channels, reducing bend stress and improving airflow clearance around CPU heatsinks, memory banks, and PCIe riser zones. With a 0.53 m overall length and split legs sized for staggered destinations, the CBL-SAST-1253-100 supports consistent reach in multi-bay architectures where backplane placement and controller location must be repeatable across node builds.

Why Choose the CBL-SAST-1253-100?

The CBL-SAST-1253-100 provides an architecturally sound way to scale internal storage connectivity while keeping lane allocation deterministic across NVMe and SAS configurations. By converting one x8 host interface into dual x4 links, it improves cabling density-to-performance alignment, supports modular backplane designs, and helps maintain enterprise reliability through clearer routing and simplified service procedures during upgrades or drive-domain changes.

Supermicro designs interconnects to align with its server and storage platform engineering, prioritising fitment accuracy, repeatable integration, and compatibility with contemporary data centre standards for maintainability, airflow management, and high-availability component access.

Key Applications:

• NVMe backplane to PCIe controller cabling
• SAS backplane to HBA/RAID connectivity
• SlimSAS x8 to dual x4 breakout in storage nodes
• Dense multi-bay server internal wiring
