Why SMI-S Doesn’t Work

In a recent post (this one on SRM), Wayne M Adams from SNIA took the time to comment as to why he believed SMI-S is alive and well. Rather than simply reply on that comment thread, I thought I would take the time to put together a summary of why SMI-S (in my opinion) hasn’t worked and will never work in the current incarnation. So let’s start with what SMI-S means.  Here’s the official definition from the SNIA website: “The Storage Management Initiative-Specification (SMI-S) is a standard designed with the purpose of standardizing and streamlining storage management functions a...

The Cyclical Nature of Storage

Perhaps I should have entitled this post “The Cyclical Nature of IT” because the same principles apply. Over time, storage moves back and forth between fully dispersed and fully centralized like a sine wave on an oscilloscope. The Evidence Look at the evidence.  In the 1950′s and 1960′s there was no choice but to be centralized. All we had was mainframe and dumb disk drives.  Storage needed a controller the size of a fridge to work and so was never going to be distributed to the masses any time soon. Then in the late 1970s, in comes Al Shugart and Seagate, giving us the first d... (more)
