Why is there a perception that you can use Cisco or NSX? If you perform a simple google search you will find many articles that aim to answer the question of Cisco vs. NSX? This is like saying HP or vSPhere? It doesn’t make any sense. Cisco and NSX can co-exist in a datacenter it’s not a one or the other proposition. Let’s face it Cisco owns the network layer in most datacenters and they should, they make damn good networking hardware. But that’s just it. They make hardware much like HP, Dell, and IBM make hardware. It has limitations.
Don’t get me wrong hardware is a necessary evil for obvious reasons for all types of virtualization whether it be computer, networking, or storage. I just don’t understand the big debate regarding Cisco vs. NSX. It’s really very simple. Keep your existing Cisco hardware and get more out of it with NSX. I hear many making an argument that network virtualization is not needed because you cannot consolidate multiple switches or routers into one. This baffles me as well. If you support this argument or feel it is valid you don’t understand the value of Network virtualization
