CBL-SAST-0639 Supermicro 31cm Cable

Enterprise Internal SATA Interconnect Cable for Server Storage Topologies with the CBL-SAST-0639

The CBL-SAST-0639 is a Supermicro internal SATA-to-SATA data cable engineered for deterministic storage connectivity inside rack servers and storage nodes, where signal integrity and serviceability are required at the same level as compute and memory subsystems. In CPU-dense platforms that rely on SATA SSD or HDD tiers behind a chassis backplane, the CBL-SAST-0639 provides the point-to-point link between drive/backplane ports and the onboard controller or HBA without introducing unnecessary mechanical strain or routing complexity.

Designed for 1-lane SATA data paths, the CBL-SAST-0639 supports clean integration with common server I/O architectures that combine PCIe expansion (for HBAs, RAID controllers, or NVMe accelerators) with mixed storage pools. The 31cm round form factor helps maintain predictable airflow corridors and reduces obstruction around risers, memory banks, and fan partitions, which is critical in high-density enclosures. As an internal interconnect, the CBL-SAST-0639 is optimized for chassis-level replacement workflows, enabling consistent cable management during backplane service events and minimizing the risk of intermittent links caused by poor bend radius control.

Why Choose the CBL-SAST-0639?

The CBL-SAST-0639 is selected when storage connectivity must remain stable under continuous vibration, thermal cycling, and maintenance access typical of enterprise racks. By using a purpose-built length and standard SATA connectors, the CBL-SAST-0639 helps preserve a high density-to-performance ratio in storage nodes while keeping troubleshooting and component swaps straightforward for operations teams.

Supermicro designs accessories with platform-level engineering discipline, aligning cabling, backplanes, and controllers to modern data centre requirements for uptime, repeatable assembly, and long-term service support across validated server configurations.

Key Applications:

• Server backplane to SATA controller interconnect
• Internal storage cabling for rack servers
• Chassis and backplane service replacement
• SATA SSD/HDD connectivity in storage nodes
