Supermicro - CBL-SAST-1222-100 Slimline x8 (LE) to 2x Slimline x4 (STR)

Internal server storage often demands high-density, high-speed connections between controllers and drives. The Supermicro CBL-SAST-1222-100 solves this by splitting a single Slimline SAS x8 port into two Slimline SAS x4 ports, enabling efficient use of available lanes without sacrificing performance. This 1-meter cable is engineered for modern SAS 4.0 environments, delivering up to 24 Gbps per lane for a total of 192 Gbps across eight lanes.

Who is it for

System integrators, data center technicians, and IT professionals who build or maintain Supermicro servers, workstations, or storage arrays. It is ideal for connecting a host bus adapter (HBA) or motherboard with a Slimline x8 connector to two separate x4 devices such as NVMe SSDs, SAS drives, or backplanes.

Tips

Ensure your host controller and target devices support Slimline SAS (SFF-8654) connectors. For optimal airflow and cable management, route the cable away from fans and sharp edges. The left-exit orientation on the x8 connector is designed for specific motherboard layouts; verify clearance before installation.
