When Terrified Vendors Attack: The Dell Edition

It recently came to my attention that Dell is now advertising some kind of benchmark that shows one of their platforms can be faster than Nimble in some very specific test of their own concoction.

While I don’t doubt that’s possible (indeed, we could do it the other way around), it may be worthwhile investigating what’s prompting the attack.

I also wanted to point out the various technically fishy points of the benchmark.

Progress Needs Trailblazers

I got the idea for this stream-of-consciousness (and possibly too obvious) post after reading some comments regarding new ways to do high speed I/O. Not something boring like faster media or protocols, but rather far more exotic approaches that require drastically rewriting applications to get the maximum benefits of radically different architectures.

The comments, in essence, stated that such advancements would be an utter waste of time since 99% of customers have absolutely no need for such exotica, but rather just need cheap, easy, reliable stuff, and can barely afford to buy infrastructure to begin with, let alone custom-code applications to get every last microsecond of latency out of gear.

Practical Considerations for Implementing NVMe Storage

Before we begin, something needs to be clear: Although dual-ported NVMe drives are not yet cost effective, the architecture of Nimble Storage is NVMe-ready today. And always remember that in order to get good benefits from NVMe, one needs to implement it all the way from the client. Doing NVMe only at the array isn’t as effective.

The Importance of Automated Headroom Management

Before we begin: This is another vendor-neutral post. I realize there may be no architecture that can do everything I’m proposing, but some may come closer to what you need than others. Whether you’re a vendor or a customer, see it as stuff you should be doing or be asking for respectively…
