Hi All.
I have been messing around with the vRealize Operations Manager to see if there is value of this in our organization. Of course management always wants a break down of the benefits that it will add and how this could potentially save money, capex and opex. I am currently looking at the Reclaimable Capacity report and Analyses. I can see we have a lot of cores and Memory that we could reclaim, but I am struggling to equate that to a $ Value.
From what I understand, if I were to reclaim this capacity, I would only be utilising the cluster more effectively, I should see drops in Balooning and CPU Wait time for those resources that are needlessly requesting cores and reclaiming memory from VM's. Our overall usage of our the Cluster would not change much? I could not work out for instance that I could drop a host out of the cluster from the reclaimed space.
How have others worked this out to justify purchase?
Regards,
Stuart
