As the requirements of assigning each VM/container a vDPA instance increases, various ways of scaling vDPA to more than 10K instances per host will be introduced in this talk. The first method is to achieve this through the co-operation with technologies provided by the cpu/chipset vendor like Scalable-IOV. The second method is done via vDPA vendor specific technology such as scalable functions. The third method is to extend the virtio specification for device slicing support. In this talk, a brief overview of vDPA will be given then a in depth discussion of the above three ways will be done. In the end, a comparison of the those three technology will be presented.
