When 720 GB of backbone just isn’t enough… start looking at the Ferrari of switching! Introducing the NEXUS 7000

The Nexus 7000 was unveiled recently by Cisco touting undoubtedly the fastest switch ever made. The 7000 has been designed to give 15 Terabytes per second backbone speed with redundancy previously only seen in large-scale military programs. It’s new revolutionary OS called NX-OS will replace the current Cisco IOS as the most robust OS yet.

The 7000 was created for the increasing requirements and bandwidth consumption of Video over IP. Conferencing, IP Surveillance, and YouTube have caused an inordinate amount of bandwidth to start crossing the wire, and the datacenter isn’t prepared for 30 frames, 4SIF video to flow to multiple streams. The 6500 series of switches currently supports 720 GBs of backbone. Take an HD stream of 45 MB/s and multiply that out. You can support about 16,000 total connections through your core before the stream starts to degrade. However, with the Nexus 7000, that number increases to over 333,000 Unicast streams.

Now I know what most of you are saying, this switch is overkill. But for a few of you out there, you have no choice but to look at the 7000 to increase your capabilities. Look for service providers to start rolling these out towards the end of this year and when the world starts to adopt a fully-fledged Video over IP system, this will be the backbone it’s carried on. When true GB just isn’t enough, and 10 GB is starting to look a little slow, then 40 GB and 100 GB networks are the requirement and the 7000 series will be the first to scale to that degree.
