I got the idea for this blog after speaking with multiple customers that were contemplating switching to certain kinds of grid computing/storage (like HCI) without fully understanding the ramifications of doing so.
You see, they were (rightly so) enamored by concepts such as automation, ease of consumption and scaling. But they forgot to ask some very important questions. See here for the dangers of getting too carried away with something new and taking things for granted.
This isn’t a post claiming HCI and grid-type storage constructs are bad. Like any tool, they can be used in various ways, some of them aggressively ill-advised. The point of this post is to help customers ask for the right configuration so they don’t get stuck with a sub-optimal and risky design.
I tried to make this post as short as possible but as someone once said, “Everything should be made as simple as possible, but not simpler”. Which, ironically, is a simplification of what Einstein actually said 🙂

I posit that we now have a whole new class of consumer that is completely oblivious to certain hitherto fundamental concepts – and this can lead to poor business decisions and overall sub-optimal execution and results.
I got the idea after a discussion with an ex colleague (that’s now working for a cloud vendor) where he proudly proclaimed that infrastructure is unimportant and uninteresting.
I’ll start generically and shift to IT. The generic aspect of this problem is very interesting, since it’s lowering quality in all sorts of fields.
And never forget: Just because something is widely and easily available doesn’t mean it’s better. It simply means that more people have access to it.

It seems there’s no shortage of creative marketing ways to fool customers these days.
I’ve written before about how to protect against some of the shadier storage business “guarantee” schemes, but a relatively new development has prompted this post.
You see, a rather large vendor-who-shall-not-be-named is now offering a capacity guarantee across their entire storage portfolio, shown right on their website. The interesting part is that their guarantee mentions not just thin provisioning but also snapshots.
Many vendors use thin provisioning in capacity guarantees – it doesn’t make the practice acceptable, merely common like influenza or selfies, only more annoying.
However, no other vendor I’m aware of has the sheer audacity to also count snapshots in their capacity guarantee.

HPE has been innovating in the Memory-Driven Compute space for a while now (for example, HPE Labs’ The Machine project and Gen-Z ).
The driver behind this has been to transform application performance, not by increments but by leaps and bounds. Think orders of magnitude in reduction of execution time. For instance, at an organization performing Alzheimer’s cure research, they had a certain key analytics operation that took 22 minutes for each iteration (and they need to do many, many iterations). With a Memory-Driven system from HPE it now takes 13 seconds. This allows the researchers to reach useful results much faster – which, in turn, means the cure could materialize in a much shorter timeframe.

In this era of over-marketing and misinformation, it can be refreshing to clarify things for customers.
Allow me to be refreshing regarding NVMe 🙂
NVMe is simply a protocol. Just like SCSI is a protocol. NVMe is most assuredly not a media type. Yet, storage vendors keep talking about “NVMe drives” and customers often think those devices are equal as long as “NVMe” is mentioned.
Alas, that’s not how things work…
Strictly speaking, there’s no such thing as an NVMe drive. Or, at the very least, calling something an “NVMe drive” isn’t enough to describe what that media is, and it’s especially not enough to describe how fast it may be.
