[c-nsp] in praise of the cat6500 Re: Flow tools

[Alessandra Forti]

Hi,

I got some money to upgrade my network infrastructure from 1Gbps to 10Gbps.

At the moment I have a cat6509E with a Sup720. This system has been 
working fine for 6 years. The upgrade will have to last a similar number 
of years and our main requirement is throughput with minimal routing if 
we are going to double the link to the outside world. My initial 
combination to support 16 racks at 10Gbps was to simply buy 
4x6716-10T-3C blades and keep the Sup720. I then got enough money to 
upgrade the Sup720 to a Sup2T with (6816-10T-2T blades). I was wondering 
if this is really necessary or if the Sup720 will last that long i.e. 
another 6 years. I'm not an expert and would appreciate your comments if 
I go down this route because the alternative is to replace the 6509 
altogether (most likely with a Force10 Z9000).

thanks

cheers
alessandra
