"Stor Util %" is a bit of a misnomer. The computation really comes down to the sum of the estimated working set sizes of all active virtual machines over the amount of DPA the scheduler thinks it has available. Since estimated working set sizes can be greater than the resident page count, values above 100% are possible. I tend not to be too concerned with the absolute value of this field as I am with large variations in it.
