Techniques for predicting the outcome of a storage management operation on a hyper-converged infrastructure (HCI) deployment are provided. In one set of embodiments, a computer system can retrieve a current storage resource state of the HCI deployment. The computer system can then execute a simulation of the storage management operation in view of the current storage resource state, where the executing includes performing one or more simulated data movements between one or more host systems in the HCI deployment. Upon completing the simulation, the computer system can generate a report including, among other things, a predicted result status of the storage management operation based on the simulation.
