Hi All,
My question might be granted but I was not able to find a clear explanation.
Question: Assuming that I want to connect 2 switches hosted in 2 different room in a datacenter. They are working in peers (flex links) and offer (of course) redundant L2 connection to servers.
Topic: patch panel.
Each switch is installed in separate rack and connection between racks is with cables terminated in a patch panel. 1 patch panel per rack. My question is related on how many 'backbone' cables I need to connect between the 2 patch panels hosted in the 2 separated racks.
Assuming to use a 24 ports patch panel per rack, assuming that I have 2 swicthes with 48 x 10Gb ports (fiber) , how many backbone cables do I need to use to connect the 2 patch panel? Just to make clear the connections I am thinking of:
Please you can use a practical example with whatever kind of 24 port patch panel to clarify my doubt or addressing me to a specific link.
Problem here is that it is not clear to me how backbone connection between patch panel is working (and I am keeping looking for this info since days).
Thanks for the support.
BR,
Fabio.

You have 20 servers, so there is 20 patches straight away. You have a number of devices which may require more than 4 patches. Patch panels usually come in 8 port modules, so the next jump up after 24 is 32.

How many servers are there that need dual connecting, since you need a cable per server?

I think I would put in 32 ports if it was me (or 48 if cost is not an issue). It sounds like there might be quite a bit of potential variation.

How did you reach this number? I just want to see the logic behind this calculation. Thanks so far for your time.
