vPars Redesigned AVIO Networking & Storage • Significantly better I/O performance vs. AVIO in a VM • Both storage (AVIO and NPIV) and networking benefit • Significant reduction of CPU utilization for I/O processing • Streamlined I/O and optimized interrupt processing 21 Bottom Line: Both vPars and VMs can use AVIO, but AVIO performs significantly better inside a vPar © Copyright 2012 Hewlett-Packard Development Company, L.P.
