CBL-SAST-0828 Supermicro 22cm Cable

High-Density Server OCuLink PCIe/SAS Interconnect Cable Assembly with the CBL-SAST-0828 for Internal Storage Fabrics

The CBL-SAST-0828 is a Supermicro internal OCuLink (SFF-8611) x4 cable designed to bridge NVMe backplanes and storage controllers where predictable lane integrity and short-reach routing are critical. In modern dual-socket CPU platforms with PCIe Gen4/Gen5 root complexes, the physical interconnect often determines achievable throughput and error rates; CBL-SAST-0828 supports a clean PCIe x4 host-to-device path to HBAs, RAID controllers, or OCuLink-capable backplanes without overlength slack that can complicate airflow and service loops.

For storage-dense chassis, CBL-SAST-0828 aligns with architectures that mix NVMe and SAS domains behind a common controller strategy, keeping the cabling layer consistent as you scale drive counts and backplane zones. The 22cm assembly is optimized for internal routing between midplane/backplane and PCIe add-in cards, enabling disciplined cable management and reducing strain on connectors during maintenance cycles.

Why Choose the CBL-SAST-0828?

CBL-SAST-0828 provides an enterprise-appropriate balance of density and serviceability for PCIe x4 OCuLink links inside rack servers, where every centimeter impacts obstruction, thermal behavior, and access. By standardizing on CBL-SAST-0828 across comparable chassis builds, infrastructure teams can simplify spares, accelerate break/fix procedures, and maintain consistent signal paths for reliable storage expansion.

Supermicro designs interconnect components to integrate cleanly with data center server platforms, emphasizing mechanical fit, repeatable assembly quality, and compatibility with common backplane and controller layouts. This engineering approach supports disciplined internal cabling that aligns with modern chassis standards and operational uptime requirements.

Key Applications:

• NVMe backplane to HBA cabling
• RAID controller to internal storage backplane
• PCIe x4 OCuLink host-to-device links
• Short-reach chassis storage expansion
