CBL-SAST-0659 Supermicro 50cm Cable

High-Density Internal NVMe/SAS Interconnect Cable Assembly with the CBL-SAST-0659 for OCuLink x8 Chassis Architectures

CBL-SAST-0659 is a Supermicro internal OCuLink x8 to OCuLink x8 cable assembly designed to link NVMe or SAS backplanes to an HBA or RAID adapter with minimal signal-path disruption in dense server storage zones. By using SFF-8611 x8 connectivity end-to-end, CBL-SAST-0659 supports direct lane mapping for PCIe-based NVMe and SAS routing where predictable topology and clean internal wiring are required.

In PCIe NVMe platforms, CBL-SAST-0659 enables compact, short-reach interconnect between front 2.5" NVMe/SAS backplanes and add-in storage controllers, helping maintain airflow and service access in 1U/2U chassis. The 50 cm reach supports common mid-plane to riser/controller placements, while the right-angled end improves clearance around backplanes, fans, and cable channels. This design aligns with storage expansion strategies that rely on consistent lane width, controlled bend radius, and stable retention under vibration, supporting high IOPS storage pools and mixed media bay configurations.

Why Choose the CBL-SAST-0659?

CBL-SAST-0659 provides an architecturally clean x8 OCuLink interconnect for high-density storage builds, balancing cabling discipline with controller-to-backplane scalability. For enterprise deployments, CBL-SAST-0659 supports repeatable internal layouts that simplify validation, reduce assembly variance across fleets, and enable predictable maintenance workflows in storage-heavy nodes.

Supermicro designs interconnect components to match server mechanical constraints and modern data centre integration practices, focusing on dependable fitment, consistent manufacturing tolerances, and compliance alignment for long-term platform standardisation.

Key Applications:

• NVMe backplane to HBA interconnect
• NVMe backplane to RAID adapter interconnect
• High-density 2.5" NVMe/SAS storage nodes
• Short-reach internal chassis cable management
