Betreff: Next step up from 6509-E/SUP720??
Hi experts,
We have a Data Center environment with all 6509-E/SUP720 on access/distribution/core layer, all with 10GE uplinks, and 1GE on the access towards to hosts. We have 18 OSPF areas, each with 2 d-core switches and 21 access switches. Each access switch holds a maximum of 240 ports.
This means:
240 * 21 = 5,040 GE of access ports on a 10GE to the distribution 5040 * 18 = 90,720 GE of distribution ports on a 10GE to the core
Obviously not all OSPF areas have 21 switches, and not all have 240 ports, and not all are fully connected, and not all are running 1 Gbps, and not all are fully loaded, but you get my drift...
The fact that no customers are complaining and that none of the uplinks are above 70% should say enough...
Yet, I am looking into how to expand the current core environment (basically
2 6509-E/SUP720 with 6 X6704-10GE blades) to something that is ready for the future.
Now, my question is: is the next step up from a 6509-E/SUP720 really only the Nexus7000 or are there other opions as well?
Thanks.
Marc
