Hi,

Thanks,  I was worried about dual home FEX to N7k.  I have ordered two 7009 and nos. of 2k.  I would like to connect n2k dual home to 2 X N7k.

I have gone through some of the articles it says...N7k doesn't support dual home FEX to two n7k.

Pls. help on this.

 

 

Hi,Sorry to disappoint, but

Hi,

Sorry to disappoint, but as of the NX-OS releases currently available i.e., up to an including NX-OS 6.2, there is no support for dual-homed FEX on the Nexus 7000 platform.

The support for dual-homed FEX is expected to be added in the NX-OS 7.0 release that is due to be FCS in the near future.

Hi,Thanks for your reply. 

Hi,

Thanks for your reply.  Either way, I can connect 2k to two upstrem 7k as different port-chennel.  Am I right?

and Server I can connect dual home to two 2k. Is it right my understanding?

 

Hi,Take a look at the

Hi,

Take a look at the document Nexus 7000 Fex Supported/Not Supported Topologies and you'll see what options you currently have.

As I mentioned, up to and including NX-OS 6.2, a single FEX can only be connected to a single Nexus 7000. This is what is shown as Figures 8, 9 and 10 in the unsupported topologies section.

A server can be connected to two different FEX, and those two FEX could be connected to a single Nexus 7000 or two different Nexus 7000. The options are shown in Figures 6 and 7.
