Not my problem
The data centre of the future can be whatever it likes, as long as it delivers the services I need, when I need them and where i need them.
The data centre is now the centre of the world. Or something. IT needs to be lean, green and mean. And fabulous, efficient and wonderful. Erm.
Data centres haven't had much of redesign in 20 years. That will change soon if Cisco has its way.
