The only thing converged in “converged infrastructure” is the purchase order
I was at a CIO roundtable in Portland a couple of weeks ago and during the introductions, one of the CIOs said, “We’ve been using hyperconverged for the past five years on a Vblock.”
My tongue still hurts from biting it. Could anything possibly be more unlike software-defined hyperconverged infrastructure (HCI) than a Vblock? As just one small example, upgrading to a new version of vSphere on a Vblock requires a complex and expensive upgrade to the Vblock itself – and the last I heard, only VCE is authorized to do this type of engagement. In contrast, Nutanix enables 1-click upgrades that not only upgrade the OS and firmware, but also the hypervisor itself.
I am surprised that some IT leaders are still confused about the difference between hyperconverged and converged infrastructure. But, then again, many industry experts still don’t understand how HCI has surpassed converged infrastructure (CI) in terms of almost every important metric. A recent ComputerWeekly article, Datacentre decisions: Converged vs hyper-converged infrastructure, for example states,“From a scalability perspective, converged systems are more suited to larger applications such as Oracle, Microsoft Exchange or SAP installations.”
