Supermicro - CBL-SAST-1236-100 Slimline x8 (LE) to 2x Slimline x4 (STR)

When building a high-density storage server, connecting a single Slimline SAS x8 port to two separate x4 backplanes or drives can be a wiring nightmare. This Supermicro Slimline SAS breakout cable solves that by splitting one x8 connection into two x4 connections, enabling clean and efficient internal cable management in compact server chassis.
