Hyper converged is not meant for a complex performance sensitive environment

Hyper Converged Infrastructure, a Future Death Trap
In late 1990s, storage and networking came out of compute for a reason. Both networking and storage need some specialized processing and it doesn't make sense for all the general purpose servers doing this job. It is better handled by the specialized group of dedicated devices. The critical element in the complete data center infrastructure is data. It may be better to keep this data in the special devices with the required level of redundancy than spreading across the entire data centers. However, hyper convergence emerged for a noble cause of ease deployment for a very small scale branch office scenarios since it is always complex to setup and operate traditional SAN. The real problem starts when we attempt to replicate this layout into large scale environment with the transactional workload. Three predominant issues can hit the hyper converged deployments hard and it can spell a death trap. While sophisticated IT houses know these problems and stay away from the hyper convergence, but others can fall prey to this hype cycle.
To make the things worse, during economic downtime which is due for some time, data doesn't stop growing but IT budget stops. IT houses tend to load the existing hardware infrastructure to the maximum level during such time. While all these performance issues related to the misfit architecture pops up, further cost cutting will kick in to reduce the IT headcount. Isn't it a real death trap which CIOs of cloud providers and enterprise need to avoid.
At the outset, Hyper convergence looks to be an attractive option seemingly providing lot of flexibility. In reality, it comes with so many limitations and curtails the flexibility to grow the resources independent of each other. In addition, a performance nightmare bound to hit once the system gets loaded.
