CBL-SAST-1258-85 Supermicro 58cm Cable

High-Density Internal SlimSAS x8 Storage Interconnect Cable Assembly with the CBL-SAST-1258-85

The CBL-SAST-1258-85 is an internal SlimSAS x8 to SlimSAS x8 cable assembly engineered for reliable 8-lane aggregation between a server backplane and an HBA/RAID controller in Supermicro-class platforms. In modern CPU and GPU-accelerated systems where storage I/O can constrain throughput, the CBL-SAST-1258-85 helps maintain a clean, low-loss internal path for SAS or NVMe lane mapping without introducing unnecessary connector transitions.

Designed for dense PCIe-based expansion and high-availability storage topologies, the CBL-SAST-1258-85 supports consistent internal routing across serviceable chassis layouts. Its 58cm length targets common 1U/2U cable paths from mid-plane/backplane regions to adapter slots, while the RE/LE orientation reduces bend stress and improves clearance around risers, airflow shrouds, and power harnesses. This makes the CBL-SAST-1258-85 well suited for lane consolidation in x8 backplane designs, enabling predictable port-to-port mapping for NVMe/SAS backplanes and minimizing maintenance time during controller swaps or backplane service events.

Why Choose the CBL-SAST-1258-85?

The CBL-SAST-1258-85 is selected when storage connectivity must match the platform’s density and service model: compact cabling that preserves signal integrity across an 8-lane path, supports repeatable routing, and aligns with enterprise replacement workflows. For deployments scaling IOPS and bandwidth per rack unit, the CBL-SAST-1258-85 enables consistent internal connectivity from backplane to HBA/RAID, reducing integration risk during upgrades and lifecycle maintenance.

Supermicro designs interconnect components to integrate cleanly with its server mechanicals, backplanes, and controller ecosystems, emphasizing dependable fitment, predictable assembly tolerances, and data centre-friendly servicing practices aligned with modern rack standards.

Key Applications:

• Backplane-to-HBA/RAID internal connectivity
• NVMe/SAS x8 lane aggregation cabling
• Service replacement and maintenance operations
• High-density 1U/2U storage server builds
