Innovation or Iteration

The word “innovation” gets thrown around a lot these days. I wouldn’t blame anyone if the word now evokes a gag reflex similar to how we all eventually reacted to “cloud” a few years back. Every product and presentation seemed to be reworked to make it appear it was a “cloud” product. It made sense […]

Does HCI Really Stand for Hyper-Connected Infrastructure?

Anyone following Enterprise IT infrastructure knows of HCI as Hyperconverged Infrastructure, or the idea of collapsing compute and storage (and sometimes networking) into easier to consume and grow building blocks, for the purpose of building a cloud-like infrastructure. If we step back, what really is happening here is part of a larger, overall IT trend. […]

PlexxiPulse—Breaking Down the Distributed Network

Most networks today (including Plexxi solutions) are built as distributed networks. This type of infrastructure reduces complexity and significantly increases network capabilities. Our own Marten Terpstra took a deep dive into the future of distributed networks this week on the Plexxi blog. He identifies and breaks down the “central command” system of today’s distributed networks, […]

I (don’t) like Big Buffers.

Recently Arista released a white paper surrounding the idea that having deeper buffers running within the network can help to alleviate the incast congestion patterns that can present when a large number of many-to-one connections are happening within a network. Also known as the TCP incast problem. They pointedly targeted Hadoop clusters, as the incast […]

Is the Facebook DC Architecture right for you?

A few weeks ago Facebook announced their new datacenter architecture in a post on their network engineering blog. Facebook is one of the few large web scale companies that is fairly open about their network architecture and designs and it gives many others the opportunity to see how a network can be scaled, even though […]

The 6 Requirements for Data Center Networks

One way or another, all data center networks exhibit at least 6 different functional areas that their operators need to engineer, implement, and operate with a differing set of needs and requirements. Similarly, in one way or another, most of the available SDN and virtualized network solutions available today or in progress aim to deal […]

Wizards are also for, well, wizards

I always enjoy reading the IPspace blog and as Ivan has stated about our blog, I don’t always agree with his opinion, but they are informative and cover just about everything networking. So this may come as a surprise, but in response to his “Do we have too many knobs” post from about a week […]

Maturity and Evolution of SDN

A few weeks ago I read this article from Craig Matsumoto on SDN Central. At first I read it with a bit of a smile, but for some reason it has actually started to bother me a little. In this article, Craig summarizes a talk by Scott Shenker about SDN and a proposal for an […]

IT’s march towards mass customization

[Unbeknownst to me, Matt Oswalt (@mierden on Twitter) posted a thematically similar post a few days before me. While I did not see that post, it seems disingenuous not to reference it, so please read his thoughts here:] IT is constantly evolving, from mainframes to disaggregated components to an integrated set of infrastructure elements working […]
