What can the experience of managing IBM mainframes teach us about designing storage for public or private cloud computing? Plenty, it turns out… In my previous post, Designing Cloud Storage? Ditch the LUN!, I pointed out the challenges of using LUNs for virtual and cloud storage environments that need to scale.
That post, and my thinking around storage management in general, were both influenced by a nine-year-old blog post by John Tyrrel: The Next Step In Virtualization. When Tyrell wrote that, the next step in virtualization was to ditch the LUN, virtualization was still pretty cutting edge. Yet, here we are, almost a decade later, and we’re still using LUNs as the storage container for most server virtualization infrastructures…
The article was way ahead of its time, and it includes one of my favorite quotes about LUNs (if you can have such a thing):…
