 > How far do you plan to expand in the next 6 years?

We currently have 10 racks and planning to add another two in the next 3 
months. Considering the density of cpu power is increasing I calculated 
around 16 racks in the next 6 years.

The rack switches will also be 10GBASE-T. This allows me more 
flexibility during the upgrade because I don't have to do a big bang 
upgrade since they are auto-negotiating.
