SDS/HCI Terminology/Definition Debate

Yesterday was an interesting learning day for me due to a tweet I responded to from one of the WhatMatrix category consultants that sparked a Twitter debate about what really constitutes hyper converged infrastructure (HCI).

Herman Rutten, category consultant for SDS/HCI at WhatMatrix tweeted that he is working on a new Landscape Report on this sector, 18 months after the release of the first one. One of the latest vendors to be included in the comparison on WhatMatrix is Datrium. This inclusion invoked reaction from some vendor representatives that they are not HCI.

This blog is not going to deny or confirm if they are – there are better-informed people than I to have that debate with. But what I do want to state is that WhatMatrix’s comparison is entitled SDS/HCI – thus encompassing all aspects in my opinion.

WhatMatrix has been comparing the HCI vendors since October 2015 and has consistently included solutions that adhere to the following three criteria:

Rule #1: The software is designed to run on commodity server hardware and makes use of the available resources therein.

Rule #2: The solution aggregates physical storage capacity from separate systems into a single shared storage pool.

Rule #3: The solution offers a broad set of storage functionality (services) comparable to traditional hardware defined shared storage systems.

Now, whether you agree with that definition or not is the basis of the Twitter debate but ultimately all solutions are reviewed with this in mind, so at least providing a consistent approach.

I do think marketing (e.g. messaging) has confused and blurred the definition for sure, but as a summary to the whole discussion Herman tweeted the following and, yes, that is what it’s all about – choice for the customer!

The new report is scheduled for publication end of September, keep an eye out for it if you want an independent, vendor agnostic viewpoint of this burgeoning market https://www.whatmatrix.com/portal/announcing-upcoming-sds-hci-landscape-report-sep-2018/.
