Putting More Brains In The Network Frees Up Compute
One of the things that high-end network adapter and switch maker Mellanox Technologies got through its $811 million acquisition of network processing chip maker EZchip last September was a team that was well versed in massively parallel processor chip design, and one that could make Mellanox a potential player in the server chip space.
But not necessarily in the way you might be thinking about it.
The reason this is the case is that in July 2014, EZchip, wanting to expand out beyond its networking chip business as Applied Micro, Cavium, and Broadcom have all done with ARM-based server chips, …

Why Troubleshooting Is Overrated
This post is the result of a thought I had after someone asked me to describe an interesting problem I’d faced. I think they meant troubleshooting, because that’s how I answered it.
Speak to most network engineers about what they love about the job, and troubleshooting will crop up quite frequently. I’ve got to admit, being able to delve into a complex problem in a high pressure situation with a clock against it more often than not does give me a rush of sorts. The CLI-fu rolls off your fingers if you’ve been on point with your studies, or you’re an experienced engineer, you methodically tick off what the problems could be and there’s a “Eureka” moment where you triumphantly declare the root cause.
But then what?
I don’t mean what’s the solution to the problem. That’s usually obvious. In most cases, the root cause is one of these culprits:
– Poor design. E.g: 1Gb link in a 10Gb path, designing for ECMP and then realising they’ve used BGP to learn a default route and not influenced your metrics, so anything outside your little IGP’s domain is going to be deterministically routed.
– A fault. E.g: Link down Continue reading

The 25GbE Datacenter Pipeline
SDN may have made networking more exciting thanks to making hardware less important than it has been in the past, but that’s not to say that hardware isn’t important at all. The certainty with which new hardware will come out and make things a little bit faster than before is right there with death and taxes. One of the big announcements yesterday from Hewlett Packard Enterprise (HPE) during HPE Discover was support for a new 25GbE / 100GbE switch architecture built around the FlexFabric 5950 and 12900 products. This may be the tipping point for things.
The Speeds of the Many
I haven’t always been high on 25GbE. Almost two years ago I couldn’t see the point. Things haven’t gotten much different in the last 24 months from a speed perspective. So why the change now? What make this 25GbE offering any different than things from the nascent ideas presented by Arista?
First and foremost, the 25GbE released by HPE this week is based on the Broadcom Tomahawk chipset. When 25GbE was first presented, it was a collection of vendors trying to convince you to upgrade to their slightly faster Ethernet. But in the past two years, most of the Continue reading
