    Hi Michael. There used to be issues where if you used the PVSCSI adapter without considering the workload, performance could actually suffer. Has that been resolved and we don't have to give type of workload any thought - just use it?

    Michael,

    What underlying storage tier are you using for these VSA tests? The IOPS seem all over the board based on the software drivers. Wondering if everything was constant at the hardware level.
