Head to head blog debate between EMC, NetApp, and HP

Chuck Hollis of EMC started a fierce debate with a blog post on how to measure effective storage capacity. Competitors from NetApp and HP responded in often sarcastic detail in the comment thread, Hollis shot back, and the volleying continued for quite a while.

I’m not a storage maven, and I don’t understand all the details of that stuff. If you’re like me in that regard, you may find the post worth skimming just to see what some of the choices, trade-offs, and complications are in designing and measuring storage systems. Stephen Foskett’s related post is also worth a look in that regard.

My recent foray into measuring disk storage pales by comparison.

    What was most interesting about this whole mess was that Chuck tries to come across as an objective industry expert. In his latest post, he so much as admitted that he was wrong about how he calculated capacity efficiency for the EVA. He then when on to make recommendations on how HP customers should set up their EVA’s.

    I don’t know about you but when I’m trying to get the best performance out of my BMW, I don’t go visit the Mercedes-Benz website to get info. Now if I only had a BMW.

    Lastly, HP has posted several responses to Chuck’s post on our blog at We’ve also issued a challenge to Chuck to have a neutral third party determine who’s array is more capacity efficient. I don’t expect Chuck and EMC to accept the challenge. The dog has a loud bark but no bite!

    I don’t think Chuck was being deceptive in what he implied about his role or biases. Vendors advise users about how to frame issues all the time. 🙂

    Thanks for dropping in your counter-argument links!
