Have you ever acquired hardware for a new project that gets killed or moved to the cloud? Has it ever been end of year for a vendor and you acquire additional hardware for future projects? Have you ever been approaching your end of quarter/year and you still have funds that need spent from your budget and you acquire more hardware? If you have ever found yourself in the above scenarios then you have also found yourself with one cluster is over sized and another cluster may need to expand resources.
If you have ever found yourself in this situation then leveraging vROPS to see if you can remove hosts from one cluster to move another will come in handy. Any time I am planning node relocations I leverage vROPs to see what my remaining resources will be. Also, see if the hosts I’m removing will give me the required resources on the other cluster. See previous article for leveraging what-if for host adds.

As you can see the what if tool for removing hosts from a cluster can be very useful. In my example I was able to show a single host could be removed and still leave remaining resources for the existing workloads. As always, I hope y’all found this helpful.
