SPDK and Nutanix AHV: minimising the virtualisation overhead Virtualising storage platforms whilst maintaining high standards of performance has been a long-term challenge for all hypervisors. The added software overhead involved in access validations, general data movement and notification between domains become more and more noticeable as physical devices get faster. That affects all sorts of performance dimensions including bandwidth, IOPS and latency, most of which have been vastly hidden by the slow n
