In the previous posts we have discussed the classic DC designs and the M-LAG solution. In this post we will cover the basic L3 fabric DC, you might never heard of it or you think that’s a solution for massive scale DC, yes the massive DC in the world would be running L3 fabric but nowadays more and more customers are moving …

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?

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:
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.
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.

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.
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
