Pros and Cons of Hyper-convergence

What is a hyper-converged solution? Well according to Network World, hyper-convergence is an IT framework that combines storage, computing and networking into a single system in an effort to reduce data centre complexity and increase scalability. This has really been a trend in the IT industry right now because of the benefits it brings. But as usual, it also has some disadvantages. In this article, we are going to give you some of the pros and cons of hyper-converged solutions.

One vendor that offers Hyper Converged Infrastructure is Hitachi ICT. They offer a multitude of other IT services that you can approach their knowledgeable consultants on. If you are serious about equipping your company with those solutions, you should check them out here: http://www.hitachi.com.sg/ict-solutions/solutions/ict-infrastructure/compute-systems.

To start, Rob Enderle will tell us more about the pros and cons of hyper-converged solutions.

The pros and cons of hyper-converged solutions

Hyper-converged solutions (in essence a software-defined system with tightly integrated storage, networking and compute resources) are all the rage at the moment. However, while I was doing a talk on trends through the end of the decade, someone who represented an enterprise class company, explained why they didn’t work for him. They’d done extensive trials from a broad number of vendors and the results made it clear that they needed to approach their problems with a more traditional solution.   I’m a fan of the concept of hyper-converged, but we so often focus almost exclusively on the benefits of this approach we forget that it also has some shortcomings.  

Let’s refresh this week.

Benefits

The clear benefits of having a highly integrated and tested system are short deployment times and relatively high reliability. This is because each component is put through a massive series of tests to assure it works with every other component and, done right, you end up with an enterprise class appliance. Basically, it is almost a data center in a box (we’ll get to the “almost” part in a minute). Read more here.

One of the benefits given is that we have a highly integrated and tested system that has short deployment times and a relatively high reliability. For the issues one that was mentioned is that part of creating a hyper-converged solution is massive interoperability testing, which can take months to complete.

Hyper-Convergence: 3 Reasons to Move, 3 Reasons to Wait

Over the last few years, hyper-converged systems have become all the rage, and for good reason. These systems can provide a number of benefits that go a long way toward making an administrator’s life easier. Even so, hyper-convergence isn’t necessarily the perfect solution. As is the case for any other IT solution, there are some disadvantages to adopting hyper-converged infrastructure. This article runs down some of the more significant pros and cons associated with the adoption of hyper-convergence.

THE PROS
1. Simplified IT
One thing that’s always amazed me about IT is how time-consuming it is to deploy a new server. I’m not talking about the act of installing an OS and an application; that part is relatively easy. I’m talking about all the planning, budgeting and so on.

One of the big selling points for hyper-converged systems is that they’re designed to greatly simplify the deployment process. All of the hardware (compute, network and storage) is sold as

a cohesive bundle (along with a hypervisor and management software). The hardware is performance-matched by the vendor to prevent any single hardware component from becoming a major performance bottleneck. The hardware components are also certified to work together, which removes any concerns about compatibility. Read more here.

For the pros, they provided three: simplified IT, it eliminates vendor finger-pointing, and it has a predictable scalability. For the cons, there are also three: they talked about the cost, vendor lock-in, and inflexible configuration options. Those are not just it because Cynthia Harvey will give us more of the pros and cons. Let us read below.

Hyperconvergence: Pros and Cons

Hyperconvergence is one of the hottest trends in IT infrastructure. Earlier this year, researchers at Gartner predicted, “The market for hyperconverged integrated systems (HCIS) will grow 79 percent to reach almost $2 billion in 2016, propelling it toward mainstream use in the next five years.” They added that the market should grow to $5 billion by 2019.

Supporting that forecast, a survey from 451 Research found that among the 32 percent of enterprises planning a major server and storage refresh this year, 86 percent expected to increase their investment in hyperconverged infrastructure.

Given the growing popularity of hyperconvergence, it should come as no surprise that a large number of vendors offer hyperconverged systems. In its Forrester Wave: Hyperconverged Infrastruture (HCI), Q3, 2016 report, Forrester named three pure-play vendors — Nutanix, Pivot3 and Simplivity — as “leaders” in the market. “Strong performers” included big-name IT vendors like Dell EMC, VMware, HPE, Cisco and Huawei, as well as smaller players like Atlantis Computing, HyperGrid (formerly Gridstore) and Stratoscale. And the report noted, “We expect hyperconverged systems to become ubiquitous, fueling a rush to market by all technology vendors.” Read more here.

One thing that was mentioned for both pros and cons is the cost. It is an advantage for cost because hyperconverged systems are based on commodity hardware so they should theoretically be less expensive than traditional servers and storage arrays, but it is a disadvantage for cost because customers say that hyperconverged systems don’t always save them money. Well, it is up for us to weigh the pros and cons of it. We just have to be wise enough to analyse.
