CBL-SAST-1263-85 Supermicro 60cm Cable

High-Density Internal Storage Interconnect Cable enabling 8-lane SAS/PCIe backplane links with the CBL-SAST-1263-85

The CBL-SAST-1263-85 is a Supermicro SlimSAS internal FFC designed for backplane-to-controller connectivity in modern rack servers where PCIe Gen4/Gen5 NVMe and 12Gb/s SAS architectures share dense chassis space. By extending an 8-lane internal SAS/PCIe pathway, the CBL-SAST-1263-85 supports high-throughput storage fabrics that must remain signal-consistent across compact service zones and tight bend radii.

In GPU and CPU platforms with high PCIe lane budgets, storage performance is often constrained by internal routing rather than controller capability. The CBL-SAST-1263-85 uses SlimSAS x8 to SlimSAS x8 termination to preserve lane integrity between host bus adapters, RAID controllers, or NVMe switch modules and the corresponding backplane. Its lane reversal support helps align backplane pinouts without compromising expansion planning, enabling predictable integration for mixed NVMe/SAS tiers, hot-swap backplanes, and balanced PCIe slot allocation.

Why Choose the CBL-SAST-1263-85?

The CBL-SAST-1263-85 provides an architecturally clean method to scale internal storage bandwidth while maintaining serviceability in dense chassis designs. It enables reliable 8-lane aggregation with minimal airflow obstruction and simplifies deployment logic where controller placement, backplane orientation, and cable routing must be repeatable across fleet builds. For enterprise environments, the CBL-SAST-1263-85 reduces integration risk in storage-heavy nodes by supporting consistent internal topology and controlled routing length.

Supermicro designs interconnect components to align with data centre standards for maintainability and platform validation. The engineering focus is on compatibility with Supermicro storage backplanes and controller ecosystems, ensuring predictable fit, routing, and long-term operational reliability during upgrades or field replacement.

Key Applications:

• NVMe backplane-to-controller internal connectivity
• SAS HBA or RAID controller to hot-swap backplane cabling
• Dense storage servers with limited internal clearance
• Hybrid NVMe/SAS tiered storage configurations
