IBM 00KF006 is a 3-meter passive direct-attach copper (DAC) cable featuring Mellanox QSFP connectors, designed for high-speed interconnect within IBM System x server environments. This cable supports 40 Gbps Ethernet connectivity and is suitable for top-of-rack (ToR) and end-of-row (EoR) switch connections, short-reach data center deployments, and server-to-storage fabric architectures. The passive design eliminates power consumption and latency, making it ideal for cost-sensitive, high-density configurations where cable runs remain under 5 meters. Compatible with IBM x3650 M4, x3650 M5, x3750 M4, and similar generation System x servers equipped with Mellanox ConnectX adapters or onboard QSFP ports. Typical applications include clustered computing, HPC node interconnection, and Ethernet storage networks requiring low-latency, high-throughput fabric links.All units tested and guaranteed functional.
