Re: Fabric Metrocluster - How many dark fibres?

Willybobs27 · ‎2013-01-04

I've looked at various bits of documentation and some suggest 2 dark fibre's, one for each fabric, whilst others show 4 dark fibre's one for each fabric and 2 for the FCVI cluster interconnects.

Which one is correct?

You need dark fibre for each remote shelf connection as well as for FC-VI port. This amounts to two optical pairs for each stack. As stacks should be mirrored, minimum that makes sense is 6 optical pairs between sites.

Hi Willybobs27

If you plan to implement TI zone (Traffic Isolation) you need 4 fiber, if not 2 can be enough

Have a look to TR3548 if you want more information about TI Zone

So this is fabric ? Initial mail had "stretch" in subject ... Then you need indeed two or four pairs depending on traffic isolation
