Top 10 data center network vendor list

In previous post was saw how handful the Gartner magic quadrants can be when learning and researching particular technology or industry trend:

• New 2012 Gartner Magic Quadrant for Cloud Infrastructure as a Service (Iaas)
• Rackspace and Brocade pushing ADX platform

Below is an another comparison chart, this time targeting vendor network equipment in data centers.

By the way I was investigating this because of the networks vendor selection on this cloud hardware deployment calculator (How to estimate hardware requirements for your private Openstack deployment ) : Dell, Cisco, HP, Arista, Juniper, Brocade.
