The Nexus 7000 will deliver up to 15 Tbps of switching capacity in a single chassis, with 512 ports for 10 Gbps ethernet, and eventually it is slated to be delivered with 40 Gbps and 100 Gbps ports. Some of the claimed performance speeds-and-feeds appear rather breathtaking:
- Copy the entire Wikipedia database in 10 milliseconds.
- Copy the entire searchable Internet in 7.5 Minutes.
- Download all 90,000 Netflix movies in 38.4 seconds.
- Send a high-resolution 2 megapixel photo to everyone on earth in 28 minutes.
- Add a Web server in 9 seconds rather than 90–180 Days.
- Transmit the data in all U.S. academic research libraries (estimated at more than 2,000 TB) in 1.07 seconds.
If nothing else does it, the 3 significant digits in the last claim tells you this is marketing-speak (read: calculated using max bandwidth assumptions), so a liberal dusting of sodium chloride is recommended.
The concept of a "data center" is currently undergoing a serious transformation and it will be interesting to see how this kind of mega-switch stacks up against alternative approaches, such Google's Data Center in a Box.
