In today's network environment, servers and appliances in the data centers, as well as control plane and application layer functions in infrastructure equipment, are increasingly being built around commodity multi-core CPUs - specifically around the x86 architecture. This CPU subsystem is being virtualized for efficient use of CPUs, better isolation, security, ease of management, lower cost and lower power. This trend is expected to accelerate. As these servers, appliances and equipment are virtualized at the CPU level, they need an underlying IO subsystem that is also virtualized. The IOV-P provides an ideal solution for IO virtualization. However, the speed with which vendors will adopt SR-IOV for such virtualization remains to be seen.
