Find out how solid-state drives are going mainstream in the data center.
Some of its customers include TransUnion, Starbucks, Hanes, and Hilton.
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 …
The post L3 fabric DC -The underlay Network -Part1 appeared first on Networkers-online.com.
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.
