The Cyclical Nature of Storage
Over time, storage moves back and forth between fully dispersed and fully centralized

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.
Then in the late 1970s, in comes Al Shugart and Seagate, giving us the first drive in a format we recognize today – the ST506. As soon as that point is reached, we can now deploy our own servers with dedicated storage and so we had the distributed storage sprawl of the early 1990s.
This quickly evolved into SAN storage, which brought us back to that centralised storage model. Since then, we’re starting to see the centralized model fall apart as storage once again goes distributed. What’s the evidence for this?
Of course the de-centralization of storage is done for good reasons, whether that’s cost, increased performance or otherwise gaining business advantage.
