Virtual I/O can be implemented in the host that’s connecting to the network and storage system, or it can be deployed in the infrastructure. Where it’s implemented may slightly alter the definition of virtual I/O. We’ll look at both approaches and describe how they’re different, as well as how they can work together. Today’s server/host barely resembles its predecessors from four or five years ago.
