The IBM 45W9399 is a 1.1-meter passive QSFP+ to QSFP+ direct-attach copper (DAC) cable rated for 40Gbps throughput. This short-reach interconnect is designed for data center and enterprise switch-to-switch, switch-to-server, or storage array connections. The passive copper construction provides low latency and power consumption compared to active alternatives, making it ideal for dense server environments and high-performance computing clusters. Compatible with IBM System x and BladeCenter infrastructure as well as standard QSFP+ enabled switches and adapters from major vendors. Typical deployments include leaf-spine fabric builds, storage appliance interconnects, and top-of-rack switching configurations requiring reliable, cost-effective 40Gb connectivity.
