This is the third article in a series about data locality in hyperconverged infrastructure (HCI). In the first article, I discussed basic math around storage network IO and the effect of data locality on the storage network load. In the second, I examined the impact of HCI configurations with more than two copies of data. I’ll wrap up with a look at how data locality is usually incomplete and at a special case of data locality.

In previous articles, I suggested that hyperconverged is just a step on a path to simpler IT infrastructure. I also explored how some of the simplification might work. Today, I’d like to explore some of the areas of infrastructure that are ripe for simplification. Some of these areas are already being addressed by some vendors, but no single vendor is addressing every area. I expect that over time, we will see more features become common on all HCI platforms. I also expect that many vendors will retain their own differentiating feature to avoid straight price competition.
In the good old days (rose-tinted spectacles required), there was only one operating system in the stack. It took care of device drivers and file IO. There were many flavours of OS, depending on the period, from UNIX and Windows to OS/2 and MacOS, and many, many others. Over time, the selection of operating systems in the data center reduced down to Linux and Windows (there are still holdouts for others, for various specific reasons, but Linux and Windows hold about 90% of the OS market). There are many flavours of Linux, but all an app developer in the enterprise really needs to know is which OS they are targeting. More and more, even that level is too low down for the app developer who is looking more at the middleware to make the final decisions.
Who or what is EUC? In an industry plagued by TLAs (three-letter acronyms), EUC, or end-user computing, is the new nomenclature for VDI, or virtual desktop infrastructure. This is not just the emperor’s new clothes, but a redefinition of the paradigm of adopting a more inclusive view of the software, hardware, and processes that shore up the client side of corporate infrastructure.
Last week, Gartner released its 2015 Magic Quadrant for Integrated Systems. I am interested in this because it includes hyperconverged infrastructure products, alongside a whole lot of other systems. One of the interesting things to see was that of the nineteen companies listed, four were new hyperconverged infrastructure companies. Of course, some of the existing vendors released products in the last year, many using VMware’s EVO:RAIL. Maybe Gartner should evaluate converged and hyperconverged separately from integrated systems that are bound to one application type.
On November 24, 2014, SimpliVity announced the general availability of its Cisco-certified solution, SimpliVity OmniStack. Fully integrated with Cisco UCS, this product is based on the C240 M3 model. Since the latter’s launch in August of this year, the hyperconverged infrastructure solution has, according to the press release, “realized tremendous global market demand, with rapid channel partner adoption and pre-orders to help customers drastically transform their data centers.”
