As a user of server virtualization tools, and a follower of the market, I’ve always thought that VMware’s lead was evident primarily on the management side of the ledger–with vCenter integration, vMotion, Distributed Resource Scheduler (DRS) and the like. Microsoft Hyper-V, I thought, was a competitive hypervisor that needed a bit more age in the bottle to develop the features that I love in vSphere. Then Overland Storage hired us to test its SnapSAN S2000 in both environments, and I saw that the same hardware could perform about 23 more more input/output operations per second (IOP) under vSphere than under Hyper-V.
