US Patent 12086083 Multi-tenant aware data processing units

Embodiments herein describe creating tag bindings that can be used to assign tags to data corresponding to different tenants using a data processing unit (DPU) such as a SmartNIC, Artificial Intelligence Unit, Network Storage Unit, Database Acceleration Units, and the like. In one embodiment, the DPUs include tag gateways at the interface between a host and network element (e.g., a switch) that recognize and tag the data corresponding to the tenants. These tags are then recognized by data processing engines (DPEs) in the DPU such as AI engines, cryptographic engines, encryption engines, Direct Memory Access (DMA) engines, and the like. These DPEs can be configured to perform tag policies that provide security isolation and performance isolation between the tenants.
