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.

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 cardinal rule for enterprise storage systems is to never compromise when it comes to data integrity and resiliency. Everything else, while important, is secondary.
Many storage consumers are not aware of what data integrity mechanisms are available or which ones are necessary to meet their protection expectations and requirements. It doesn’t help that a lot of the technologies and the errors they prevent are rather esoteric. However, if you want a storage system that safely stores your data and always returns it correctly, no measure is too extreme.

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…

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.
