Cisco Data Center Network Manager (DCNM) – Initial Feedback

Recently I had a chance to try using Cisco’s Data Center Network Manager (DCNM) software in anger. I must confess that sometimes anger was the right word, but at other times it definitely made me smile. Based on the state of the documentation it’s clear that there are a couple of areas where very few people have spent time digging in (if they had, the same errors wouldn’t be in the documentation for at least 5 releases of DCNM), so on that basis I’m using this post—and more to follow—to document some of the fun things I have discovered along the way. For reference, I am running DCNM version 10, so there have been nine previous versions of DCNM in which the behavior can be perfected, and I gather that version 10 is a big step up from version 9.

To put my testing in context, I have a specific FabricPath Leaf-Spine topology already designed, and I am only using the aspects of DCNM pertinent to my particular needs for an Ethernet LAN fabric. I say this up front because I know that I am not using all of DCNM’s functionality, and perhaps I’m missing out on some of the fabric automation Continue reading

D-Wave’s $15 million quantum computer runs a staggering 2,000 qubits

For D-Wave, the path to quantum computers being widely accepted is similar to the history of today's computers. The first chips came more than 30 years ago, and Microsoft's Basic expanded the software infrastructure around PCs. Quantum computers are a new type of computer that can be significantly faster than today's PCs. They are still decades away from replacing PCs and going mainstream, but more advanced hardware and use models are still emerging. "A lot of that is unfolding and will have a similar dramatic change in the computing landscape," Vern Brownell, D-Wave's CEO, said in an interview. D-Wave is the only company selling a quantum computer. It sold its first system in 2011 and is now pushing the speed limits with a new quantum computer called the D-Wave 2000Q, which has 2,000 qubits.To read this article in full or to leave a comment, please click here

BT Openreach to trial Dark Fibre Access in August 2017

When the government owns the fibre and copper cabling but leaves the operation and revenue extraction to commercial companies you get competitive telecoms

Openreach’s DFA product will allow rival internet service providers (ISPs) access to the company’s fibre-optic cables, which technically means that they can install their own equipment at either end of the optical fibre, within Openreach’s cable ducts.

New Webinar: PowerShell for Networking Engineers

Ansible (or Python+Paramiko/Netmiko) seems to be the tool used in most do-it-yourself network automation presentations and videos. Did you know there’s a scripting/automation alternative that’s hugely popular in parts of sysadmin and virtualization universe that almost nobody talks about in networking (because everyone is focused on huge data center fabrics and unicorns) – PowerShell (now also available on OSX and Linux).
