CBL-SAST-1256A-85 Supermicro 56cm Cable

Enterprise SlimSAS x8 Internal Storage Interconnect Cable engineered for dense backplane cabling with the CBL-SAST-1256A-85

The CBL-SAST-1256A-85 is a Supermicro SlimSAS internal data cable designed to link storage controllers to SAS/SATA/NVMe backplanes in rack servers and storage chassis where signal integrity and deterministic lane mapping are critical. As an 8-lane SlimSAS x8 to SlimSAS x8 interconnect with 2 male connectors, the CBL-SAST-1256A-85 supports high-throughput storage fabrics within the chassis while keeping cabling consistent across multi-bay backplanes and modular controller layouts.

In PCIe and SAS/SATA storage architectures, internal interconnects can limit effective bandwidth and serviceability if routing is constrained. The CBL-SAST-1256A-85 uses a left-exit to straight cable routing profile to reduce bend radius stress and simplify clean cable paths in front-to-back airflow designs. With a 56cm length, the CBL-SAST-1256A-85 is optimized for midplane and backplane-to-HBA/RAID or NVMe switch cabling, enabling predictable reach across common 1U/2U/3U Supermicro platform geometries without excess slack that can obstruct airflow or complicate maintenance.

Why Choose the CBL-SAST-1256A-85?

The CBL-SAST-1256A-85 provides a controlled, platform-aligned interconnect for scaling internal drive connectivity while preserving serviceability and signal margin across 8 lanes. For storage-dense deployments, the CBL-SAST-1256A-85 supports repeatable cable management practices, reduces integration risk during chassis expansion, and helps maintain consistent backplane wiring standards across fleets.

Supermicro engineers cabling and interconnect options to match server mechanicals, backplane pinouts, and enterprise reliability expectations, enabling predictable integration with modern data centre requirements for airflow, maintenance access, and component standardization.

Key Applications:

• Internal SAS/SATA backplane to HBA/RAID controller wiring
• NVMe backplane to PCIe switch or controller interconnect
• Storage expansion cabling in rack servers and JBOD chassis
• Standardized backplane wiring for fleet deployments
