Best Design
« on: February 14, 2014, 08:04:52 PM »

     Having trouble deciding what is best for the following scenario..

If i have about 20 buildings in a campus, with 1 core in the main DC and another core 1 mile away in a DR buidling. Both have to be used. Would it be best to have a distribution in each building and connect back to the cores as a hub and spoke...OR should i connect all buildings together in a ring type deployment? These buildings are sometimes very far about 2 miles from the core DC.

Hub and spoke vs ring type deployment?

Any advise or right way of thinking/best practice would be useful.

Thanks :)

so many variables.
what vendor are you using, what routing protocols, budget....etc etc.

I would start getting cabling quotes for both solutions.  That will be the biggest factor and the biggest cost to this project.

If cabling isn't an issues I would go with a hybrid, star and ring topology.

I would consider a ring topology between the buildings and distribution/access within each.
With your distances, if you are considering fully meshed, you would need singlemode from each building and to each core, along with single and 50 Micron Multi-mode between each.

Without an idea of the traffic requests, it tough to design - Way too many ways to provide redundant services, some at higher costs than others.  In the old FDDI days, it was easier...

When you build up everything new I would take a look at SPB.
With SPB you could use nearly any physical topology in your network and would not need the oldschool 3 tier
design with all its restrictions.

Itīs always the networks fault!

Using the ring deployment would probably cost less in cabling.
