When working with Server and VMware people, there is a fair amount of misunderstanding of what is happening in the network. The best technical explanation for what is happening in LAG is, of course described at Ivan Pepelnjak’s IPSpace Blog – vSphere Does Not Need LAG Bandaids – The Network Does while Chris Wahl talks about the server side for VMware but I wanted to add something to the debate.
Stumbled over “AgilePorts” feature in Arista products this week: Arista’s AgilePorts technology enables the combination of four 10GbE SFP+ interfaces into a single 40GbE interface leveraging the parallel lane technology present in the 40GBASE-CR4 and 40GBASE-SR4standards. With AgilePorts, each 10GbE interface emulates one of the four parallel lanes, which are then driven by a 40GbE […]
Cisco has a built a single technology strategy for fixed and wireless networking and called it Unified Access Data Plane (UADP).
Summary of the key elements of the Shortest Path Bridging Protocol IEEE 802.1aq.
In the Cisco UCS servers, there are three classes or categories of Network Adapters for B-series and C-Server servers. I write this down because it’s pretty hard to find this summary anywhere is Cisco’s documentation and I keep having to tell people the difference. Now I can point them at this blog post.
Sometimes you need to use many different Proxy Auto Configuration files with a web browser, usually when testing or trying out new installation of the proxy servers.

When it was announced last year,it was noted that the underlying physical design is a completely different approach to building Switch Fabrics. Here I’m taking a loosely research based approach to understand how Juniper QFabric is different from all other approaches to the problem, and also a look at some of the challenges ahead.
