Lying via Capacity Guarantees

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 Memory-Driven Architectures Extend to 3PAR and Nimble Storage

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.

Media is Not Created Equal and NVMe is Just a Protocol

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.

Are Snapshots backups? And what do you need to protect against?

I got the idea for this post from a Twitter thread. I thought such discussions were dead but clearly they’re not, and decided to shed some light on this, having dealt with backup at insane scale in a previous life.

It doesn’t matter what a feature is called – can you use it to recover? And, if the answer is yes, how quickly and under which scenarios? And what are the downsides?
