As the role of the storage admin changes; the toolset will change and we will need new tools that assist us. Modelling tools that enable us to work with our workloads are generally very expensive and often have rather dubious ROI models that allow us to justify them to our management.
And you rarely need them but it you are heading into a refresh cycle for example and you don’t necessarily always trust the vendors to mark their own homework..a tool is useful, especially one that you can model your own workload on.
So this tool from the newly merged Load Dynamix and Virtual Instruments looks interesting; I’ve not had a play yet and am not sure of the limitations but free is hard to beat..
Hopefully more vendors and the community will get involved and add more potential data sources..
