PPP Show 38 – Comparing Data Centre Fabrics From Juniper, Brocade and Cisco
25th March 2011 by 2 Comments
Kurt Bales has a customer who wants to buy a new Data Centre Network and the three main networking vendors (Juniper, Cisco & Brocade) have pitched at him and the customer. Kurt then contacted the Pushers and said “This would make a great podcast to talk about how it looks, works and the reality of the so-called “Data Centre Fabric networks, plus I’ve got some questions that I’d like to get some second opinions.”
So we rounded up Ivan from IOS Hints and Greg from EtherealMind to record a fast, furious and focussed look at the state of play with the three data centre fabrics today. Lots of speculation, wild guesses and deep diving followed. I learned heaps.

QFabric – What Excites Me!
1st March 2011 by 8 Comments
I was intrigued and excited about the Junipers announcement last week of QFabric. I was vaguely aware of TRILL and Cisco implementation (Fabric Path), but came to the table (so to speak) with no pre-conceptions of what I might expect. SCI-FI – Is this just me? Is the Q in QFabric taken from sci-fi [...]
Controller Based Networks for Data Centres

The current technologies of data centre networks don’t address the fundamental scaling issues. You can’t scale to hundreds of independent switches, we need to have less control planes for more coherent functions. Here is my take on next wave of networking in the data centre beyond DCB and TRILL.

Would You Implement a Proprietary L2 ECMP Protocol Today ?
5th December 2010 by 2 Comments
So Cisco’s much ballyhoo’d FabricPath protocol for “Data Centre of the Future” is proprietary. Not an extension or a fancy product name. Full ‘EIGRP style’ we own it and you can’t have it. What’s that all about ?
