Hi,

I will prefer to connect your 5000 to the 7500 by EX ports on 7500. So your fabrics will not merge but still be seperated.

Ok thanks

But after i connect the 5000 to 7500 ..how do u brefer to connect the two 7500 routers to each other? by ve port or by vex

Thanks in advance

Hi,

we only have three 7500 for three sites. So I decided to connect them by VE ports to get one fabric. Our benefit is that our backbone is build as a ring where all three sites are connected to so if there is one link down FCIP will reroute it automatically.

But I´m not sure which connection options are supported by brocade for you (two sites each two 7500). Have a look at admin guide of your FOS. Possible I would build two fabrics for 7500 each site one together.

Could you tell a bit more about your backbone infrastructure?

hi
we only have 1 7500 for each site(we have 2 sites ..1)Main 2)DR

hosts connects to the 5000 switch and we still hane the 7500 not connected we need to use them for mirror view replication only

Ah ok, so a single point of failure ? Well, two actually...

Ok, I understand your point, but remember that 2 paths are also faster ! And I don't know how latency impacts your production, but 2 paths - SPA over1 and SPB over the other) means lower latency and better respons times for your hosts / apps.

Thanks for your idea about the latency ..we have all sites with mds switches and brocade without SPOF ..only this site was designed with SPOF.

but if we connected the the way of ex-e from 7500 to 5000 on each site an then connected the ve-ve from 7500-7500 ....would the fabrics in 5000's merge?

note : nothing is connected to 7500 ports except the ex port to the 5000

yes SPOF ...but it is just for replication.
