With vSphere 8 and NSX 4, VMware has introduced support for SmartNICs or Data Processing Units (DPUs). The DPU implementation in vSphere is called vSphere Distributed Service Engine.
DPUs (SmartNICs) are network cards with built-in intelligence that can perform various network functions directly on the adapter through their own programmable processors. In addition to the networking accelerators, DPUs like NVIDIA BlueField also have general-purpose Arm processor cores that can run a full ESXi general system.
With the DPU technology, NSX services like routing, switching, firewall and monitoring are offloaded to the DPU from the host hypervisor. With these capabilities, it is possible to improve performance, free up resources on the host and isolate workload and infrastructure domains.
