Collection of useful, relevant or just fun places on the Internets for 29th April 2012 and a bit commentary about what I’ve found interesting about them:
Brand Inertia: Is Cisco Your Most Trusted IT Partner? – Ethan writes about his failing trust in Cisco, specifically, and big vendors more widely.
That’s a very telling sort of a question to ask of the partners you rely upon to help spread the Cisco gospel. The question implies something that I think is critical to understanding a perception of Cisco in the marketplace right now: Cisco has lost some of the trust they once had. Without a doubt, Cisco will remain a ubiquitous presence in the data centers and enterprise networks of the world for years to come. And yet, somehow things are different. Some in the marketplace are looking at Cisco with crossed arms and furrowed brows, and starting to bring in competitors for exploratory meetings. Implicit trust in Cisco wares and the Cisco brand is not taken for granted in circles where once it was.
This post has had a huge response, comments, email and much more. You MUST read this. I certainly agree with his points. The momentum against Cisco appears to have started and I’m truly beginning to wonder if they can turn it around.
In my industry reading this week, I came across the following notion a few times: getting hacked is inevitable – therefore, work on mitigating & containing the damage as much you work on border control. I don’t suppose anyone in the security business is getting ready to chuck their firewalls and IPS units out the door on the assumption that they’ve been hacked already, but the larger question raised was still a scary one to me. Are we really giving up hope that we can prevent a breach on our networks?
Brilliant. Act like you have already been hacked and you will have the correct security posture.
Full mesh is the worst possible fabric architecture « ipSpace.net by @ioshints – Just because you can, doesn’t mean you should……..
One of the answers you get from some of the vendors selling you data center fabrics is “you can use any topology you wish” and then they start to rattle off an impressive list of buzzword-bingo-winning terms like full mesh, hypercube and Clos fabric. While full mesh sounds like a great idea (after all, what could possibly go wrong if every switch can talk directly to any other switch), it’s actually the worst possible architecture (apart from the fully randomized Monkey Design).
The current state of IPv6 support in many vendors products makes me want to donkey-kick someone right in the… well, let’s just say it upsets me.
I have been leading an IPv6 roll-out for some time now, among other things, and have found some interesting and widely differing levels of support for the next generation Internet Protocol. With some vendors, many things work and work well, while with others it’s as if things haven’t changed in a decade or more. Even with the vendors who do have relatively good support for IPv6, however, there remains often odd, even inexplicable, gaps in that support. This has made our deployment a lot more challenging than it needed to be.
Cisco Application Control Engine 4710 « Cisco Inferno – Everyone wants to like the Cisco ACE platform but no one does.
Cisco ACE is ACE. I am finding that this statement is a semi-truth. Before inheriting this network with a few ACE clusters, I did some reading. A light google confirmed what I had read on the Twitters but I wanted to find out for myself. It was like Cisco with this device threw a 44 gallon drum of petrol into a bonfire. The catalyst to open revolt.
Did webscale computing force Intel’s Cray buy? — Cloud Computing News – Intel has bought several interconnect companies including QLogic infiniband assets recently. It’s the start of a trend. It’s called fabrics, but probably on the CPU.
Hence buying the engineers, IP and expertise of Cray, which pioneered interconnect technology that allows thousands of chips to communicate at high speeds. Chips are always going to be important inside servers, but now it’s time for fabrics to shine too.
Loopback Mountain: CCIE: Five Year Reflections – Lots of great points here. Great look back at career over the last five years since he passed his CCIE exam – which, BTW, changes your career in a lot of strange ways.
I passed the CCIE Routing & Switching lab five years ago today. Back then my number seemed enormous, but now five years later I’m already below the halfway point (as of this writing I believe the numbers are in the mid-to-high thirty-thousands). A lot has changed since then: it seems like “data center” and “cloud” have taken over almost completely as the hot topics in network engineering (with “software defined networking” hot on their heels), and it seems like Cisco has lost some of its shine due to its rapid diversification into markets outside pure networking and the rise of tough competitors in networking niche markets. We’ve gone through a huge economic contraction that we may or may not be exiting. In the certification world, Cisco has added several new tracks, and other companies have added their own coveted expert-level certifications.
Solarwinds NPM and Netflow Monitor FTW – Brandon reviews Solarwinds Netflow Monitoring. Lots of pictures!
I’ve had the opportunity to work with Solarwinds Orion again and every time I look at it I am amazed at the visibility I have, and sometimes overwhelmed by it. However, the more I dig into it the easier it gets to understand what it’s showing me. For example, in the screenshot below I am looking at the Netflow Conversations summary. I’ve noticed here that over half of my data is is one type of conversation.
When Will This Low-Innovation Internet Era End? | Wired Opinion | Wired.com – Provocative and thought provoking.
A hundred years from now, he said, we might look back on the late 20th and early 21st centuries and say, “It was an actively creative society. Then the internet happened and everything got put on hold for a generation.”
