Description
The Lenovo ThinkSystem NVIDIA BlueField-2 25GbE SFP56 2-Port PCIe Ethernet DPU with BMC & Crypto is a data processing unit (DPU) network adapter designed as a field upgrade to add a second DPU to an existing single-DPU ThinkSystem SR650 V3 configuration. It requires the companion NC-SI cable (4X97B02130) for proper installation and is intended specifically for DPU-specific CTO server models that already have one DPU installed.
