I have a task to totally redesign a huge network which consists of about 150 switches (old enterprise CISCOs). Everything is located at factory's territory. Take a look at the attached picture, this is a classic "star" topology. It's current topology.
The core of the network will be located in two separated DPC, there will be about 300 meters between them (Now it's two 6509 bounded by VSS in a same location).
I will replace all cores, distribution and 90% of access switches.
The main goal is to optimize bandwidth and increase redundancy and fail-tolerance to maximum level.
What is the most suitable topology for these goals?
Could Extreme offer something more than MLAG for core, stacks for distribution and LAGs everywhere?
I wonder how Extreme Fabric is suitable here, but there is no any success stories around...
Many thanks in advance,
