What does a BlueField DPU offload from the host CPU?
Why B is the answer
Networking, storage and security tasks
A DPU runs infrastructure work on its own processor, which frees the host.
In detail
- A DPU offloads networking, storage and security tasks.
- It has its own processor.
Use case
An illustrative scenario, not a real incident.
Network encryption moves to a BlueField DPU, which frees the host's CPU.
