Supermicro - CBL-SAST-1103 SLIMLINE x8 to 2x Oculink x4

Modern servers and storage arrays demand high-speed, reliable connections between host controllers and NVMe or SAS drives. The Supermicro CBL-SAST-1103 addresses this by converting a single SlimSAS 8i (SFF-8654) host port into two OCuLink 4i (SFF-8611) device ports, enabling you to connect two NVMe or SAS devices to one controller. With support for PCIe Gen4 speeds up to 16 GT/s per lane, this 70cm cable ensures your data flows without bottlenecks, even in dense, high-performance environments.

Who is it for

This cable is ideal for system integrators, IT administrators, and enthusiasts building or upgrading servers, workstations, or storage arrays using Supermicro motherboards or RAID controllers. If you need to maximize storage density and performance by splitting an 8-lane SlimSAS port into two 4-lane OCuLink connections, this cable is the perfect solution.

Tips

When connecting NVMe drives, ensure your motherboard or RAID controller supports PCIe bifurcation to split the 8-lane SlimSAS port into two x4 links. For optimal performance, use this cable with Supermicro backplanes that feature OCuLink connectors. Always handle the cable by the connectors to avoid damaging the shielding.
