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 SSD (and other) Firmware Updates

I wanted to bring this crucial issue to light since I’m noticing several storage vendors being either cavalier about this or simply unaware.

I will explain why solutions that don’t offer some sort of automated, live SSD firmware update mechanism are potentially extremely risky propositions. Yes, this is another “vendor hat off, common sense hat on” type of post.

Going Green: Why I Joined Nimble Storage

I am proud to announce that, as of today, I am a member of the Nimble Storage team.

This marks the end of an era – I spent quite a bit of time at NetApp: learned a lot, did a lot – by the end I had my hands in all kinds of sausage making… 🙂

I wish my friends at NetApp the best of luck for the future. The storage industry is a very tough arena, and one that will be increasingly harder and with less tolerance than ever before.

Architecture has long term scalability implications for All Flash Appliances

Recently, many vendors announced the availability of large SSDs. It’s not extremely exciting – it’s just a larger storage medium. Sure, it’s really advanced 3D NAND, it’s fast and ultra-reliable, and will allow some nicely dense configurations at a reduced $/GB. Another day in Enterprise Storage Land.

But, ultimately, that’s how drives roll – they get bigger. And in the case of SSD, the roadmaps seem extremely aggressive regarding capacities, with 100TB per device coming.

Then I realized that several vendors don’t have large SSD capacities available.

But why? Why ignore such a seemingly easy and hugely cost-effective way to increase density?

In this post I will attempt to explain why certain architectural decisions may lead to inflexible design constructs that can have long-term flexibility and scalability ramifications.
