Q&A: Building a Layer-2 Data Center Fabric in 2016

One of my readers designing a new data center fabric that has to provide L2 transport across the data center sent me this observation:

While we don’t have plans to seek an open solution in our DC we are considering ACI or VXLAN with EVPN. Our systems integrator partner expressed a view that VXLAN is still very new. Would you share that view?

Assuming he wants to stay with Cisco, what are the other options?

US Supreme Court leaves gap in Samsung-Apple patent ruling

The U.S. Supreme Court on Tuesday ruled in favor of Samsung Electronics and its backers in the industry in a design patent dispute with Apple, when in a 8-0 decision it said that “the term 'article of manufacture' is broad enough to embrace both a product sold to a consumer and a component of that product, whether sold separately or not.”But the top court has left a lot unsaid, including by not providing guidance to the U.S. Court of Appeals for the Federal Circuit on how the damages Samsung has to pay Apple for the infringement of smartphone design patents will have to be calculated. That could also delay for a long time the resolution of the patent dispute between Apple and Samsung, which has already dragged on for a number of years.To read this article in full or to leave a comment, please click here

Facebook, Google, World Wide Technology near top of Glassdoor’s Best Places to Work 2017 list

Depending up on how loosely I define "enterprise technology vendor," I'd say about a third of the 2017 Glassdoor Best Places to Work in the U.S. list consists of companies that supply IT professionals and those they support.Facebook (hey, they sell Workplace collaboration tools) is all the way up to #2, rising from #5 last year, and Google (#4), system integrator World Wide Technology (#5) and Adobe (#9) are all among the top 10. Consulting firm Bain & Co., is #1 for the third time since 2012, and replaces Airbnb as top dog this time around in the 9th annual rankings.To read this article in full or to leave a comment, please click here

Learning Environments for OVN

Over the last few days, I’ve added two new Vagrant-based learning environments to my GitHub “learning-tools” repository, both of them focused on Open Virtual Network (OVN). OVN, if you aren’t aware, is part of the Open vSwitch (OVS) project aimed at adding open source network virtualization functionality to OVS. If you’re interested in learning more about OVN, you may want to check out these new learning environments.

Here’s more details on the two new learning environments:

  1. The first one, found in the “ovn” folder of the repository, just builds out a simple three-node OVN 2.6.0 environment running Ubuntu 16.04. This would allow you to run OVN commands like ovn-nbctl, ovn-sbctl, ovs-vsctl, and other related commands to better understand how the components interact with each other and how OVN works.

  2. The second environment, found in the “ovn-docker-ansible” folder, builds on the first one by adding Docker Engine to each node in the environment and adding the OVN driver for Docker networking. In addition to being able to run various OVS and OVN commands, this environment allows you to build OVN-backed overlay networks between Docker containers running on any node in the environment.

New oVirt Project Underway

As oVirt continues to grow, the many projects within the broader oVirt community are thriving as well. Today, the oVirt community is pleased to announce the addition of a new incubator subproject, Vagrant Provider, as well as the graduation of another subproject, moVirt, from incubator to full project status!

According to maintainer Marc Young, Vagrant Provider is a provider plugin for the Vagrant suite that enables command-line ease of virtual machine provisioning and lifecycle management.

More on Vagrant Provider

The Vagrant provider plugin will interface with the oVirt REST API (version 4 and higher) using the oVirt provided ruby SDK 'ovirt-engine-sdk-ruby'. This allows users to abstract the user interface and experience into a set of command-line abilities to create, provision, destroy and manage the complete lifecycle of virtual machines. It also allows the use of external configuration management and configuration files themselves to be committed into code.

As Young explains in his project proposal, the "trend in configuration management, operations, and devops has been to maintain as much of the development process as possible in terms of the virtual machines and hosts that they run on. With software like Terraform the tasks of creating the underlying infrastructure such as Continue reading

Say goodbye to MS-DOS command prompt

My very first technology article, back in 1987, was about MS-DOS 3.30. Almost 30 years later, I’m still writing, but the last bit of MS-DOS, cmd.exe — the command prompt — is on its way out the door. It’s quite possible that you have been using Microsoft Windows for years — decades, even — without realizing that there’s a direct line to Microsoft’s earliest operating system or that an MS-DOS underpinning has carried over from one Windows version to another — less extensive with every revision, but still there nonetheless. Now we’re about to say goodbye to all of that. Interestingly, though, there was not always an MS-DOS from Microsoft, and it wasn’t even dubbed that at birth. The history is worth reviewing now that the end is nigh.To read this article in full or to leave a comment, please click here
