Today, every business is powered by software, and having a DevOps strategy is key to innovation and developer productivity. Pure can help. A data-centric architecture from Pure Storage ...
Customers and IT professionals I encounter are increasing interested in and challenged by the emergence of convergence as a new model for IT infrastructure delivery. The two broad topics of discussion refer to converged infrastructure (CI) and hyper-converged infrastructure (HCI) — how they differ, how they’re similar, and what’s best for a given workload. This post will enlist the help of some well know industry luminaries to help break through the hype surrounding these architectural approaches and help you make sense of the emerging converged landscape.
In the past few months I’ve had the pleasure of working with Vaughn Stewart (Pure Storage), Terri McClure (Enterprise Strategy Group), and Howard Marks (DeepStorage.net) exploring the value inherent in various models for convergence — specifically comparing CI and HCI. Their discussions have ranged from business value and buying models to deep technology discussions and dissections of architecture. These are real experts in the field and their input and insight is pretty fantastic.
I think a good place to start the discussion of CI and HCI is with this quick video of Terri McClure and Vaughn Stewart reviewing Terri’s research into CI and HCI at ESG. Terri provides some great tips for those considering convergence, particularly ramifications for scaleability, network design, and ongoing management costs.
If you’d like to read Howard Marks’s analysis of HCI in the world of all-flash storage, he offers some insight into how to calculate real-world costs of ownership of both CI and HCI. Howard specifically compares the Cisco and Pure Storage FlashStack CI solution to HCI from a popular vendor — it’s obvious where he believes the most value lies.
Last, but not least, Howard Marks and Vaughn Stewart presented two sessions at the recent //Accelerate conference in San Francisco. If you missed the conference, you can watch a recording of their CI/HCI sessions to learn more about their thoughts on the TCO of converged architectures and why they’re increasingly being adopted.
If you’ve reviewed these docs and still have questions, I know all three of these folks would love to share more of their research and findings with interested parties. You can reach them here:
