It’s an undeniable fact that many customers, while they would love to use the highly advanced features of modern disk arrays, have already made a big investment in legacy storage. Sure, it doesn’t have all the great features, but it’s already there, frequently there’s a lot of it, and the maintenance isn’t expiring for another year or two so it’s not economically feasible to get rid of it.
So, are there any independent bloggers? Really?

Due to the craziness in the previous blog, I decided to post an actual graph showing a NetApp system I/O latency while under load and a disk rebuild. It was a bakeoff vs another large storage vendor (which NetApp won).

I’m all for a good fight, but in the storage industry it seems that all too many creative liberties are taken when competing.
Let’s assume, for a moment, that we’re talking about the car industry instead. I like cars, and I love car analogies. So we’ll use that, and it illustrates the absurdity really well.
