Traditional vs Converged vs Hyper-converged Infrastructure — What to choose

This post is a follow-up to the one about picking the right storage solution (DAS, NAS, SAN: Which is the right one for you?), so if you haven’t read that yet, make sure to do so before continuing, so you’ll have a good understanding of how both decisions impact the other.

In this post, I’ll cover the types of infrastructures commonly used by organizations and the primary differences between them.

The types of infrastructure I’ll be covering are:

• Traditional infrastructure
• Converged infrastructure (CI)
• Hyper-converged infrastructure (commonly referred to as HCI)

Traditional infrastructure

With traditional infrastructure, you purchase components such as storage arrays, servers, and network switches and put them in a rack. The benefit this brings is that you can handpick the right components for you, for example, in terms of performance or from a cost perspective. This also means you can select everything from the same vendor or combine different ones to your liking.
Another advantage is that you can also upgrade individual components. Need more computing power? Just replace the servers with newer and faster models.
