CBL-SAST-1254F-85 Supermicro 54cm Cable

High-Density Internal SAS/NVMe Interconnect Cable for Backplane Lane Routing with the CBL-SAST-1254F-85

CBL-SAST-1254F-85 is a Supermicro internal SlimSAS x8 to SlimSAS x8 FFC designed for precise SAS/SATA or PCIe/NVMe lane routing between a storage controller/HBA and a server backplane in dense rack platforms. By maintaining a consistent 8-lane interconnect path, CBL-SAST-1254F-85 supports modern storage architectures where CPU-attached PCIe Gen4/Gen5 NVMe, tri-mode HBAs, and SAS expanders coexist and require deterministic signal continuity.

In multi-bay chassis, interconnect integrity directly impacts throughput and serviceability. The flexible flat cable construction and left-exit to straight routing help align with tight internal airflow channels and constrained cable management zones, reducing mechanical stress at the connectors during maintenance cycles. With 2 SlimSAS x8 male terminations and a 54cm span, CBL-SAST-1254F-85 is optimized for backplane-to-host topologies where PCIe lane mapping, port bifurcation, and backplane zoning must remain stable across node rebuilds, controller swaps, and spare-part standardization programs.

Why Choose the CBL-SAST-1254F-85?

CBL-SAST-1254F-85 provides a controlled, platform-aligned interconnect that preserves storage lane topology without introducing unnecessary adapters or routing variability. For enterprise operations, this improves density-to-performance outcomes by keeping backplane cabling predictable, supports scalable service models through repeatable part numbers, and reduces downtime risk during hot-aisle service events where rapid, correct reconnection is mandatory.

Supermicro designs interconnect components to match chassis and backplane mechanical constraints, prioritizing fit, routing discipline, and long-term maintainability. This engineering approach supports data centre standards for modular service, consistent spares, and validated internal connectivity across storage-heavy compute nodes.

Key Applications:

• NVMe backplane interconnect in PCIe storage servers
• SAS/SATA backplane cabling for HBA and RAID controllers
• Spare standardization for Supermicro chassis fleets
• High-density storage node maintenance and re-cabling
