Hi Guys,
Until now i used to know one topology - 2 FIs , each one connected to his own N5K .
Now, we need to build from scratch an environment with 2 FIs, but only one N5K .
I need some help to understand what I need to do . I can't find myself :/ . need someone that will "show me the way" .
I want to work with two different VSANs [let's say 20 for fabric A, and 30 for fabric B] .
1. Which ports should i connect from the FI the the N5K ? regular ports ? or FC ports ?
.2 Then , what should i configure on the N5K on those ports ? port-channel for each fabric , and also VFC ? or what ?
3. And, what should I configure in this area at UCSM ? [see screenshot]
I'm sorry for the non-well organized question , it's because i'm very confused ....
Any logical assistant will help , anything that will lead me to understand what I need to do .
Big thanks in advance ,

Hi Ron
With one N5k, you have of course no HA !
Regarding FC; you create a logical dual fabric on a single N5k, separating them e.g. with their own VSAN's.
Regarding Ethernet, any vpc is of course not possible, classical pc however are possible. Your UCSM cannot see any difference to a real dual N5k configuration.
I hope this is not a customer design, only for your lab :-)

Hi Wlater , thanks for your reply
Of course it's for our lab :]
I did the following connections, will you be able to let me know if it can work ?
FI-A connected to n5k with 2 fcoe cables, configured as Unified Uplink .
FI-B connected to n5k with 2 fcoe cables, configured as Unified Uplink .
On the n5k , i did those configs :
1. created Port-channel for those two links from FI-A [Po201] , and Port-channel for those two links from FI-B [Po202] . (of course they are in mode trunk)
2. I bind Po201 to VFC1 [VSAN 1021] , and Po202 to VFC2 [VSAN 1022]
Until now, it's fine on the n5k side ?

Hi Ron
Looks ok to me; question: what is your storage ? FC, or FCoE, or IP (iSCSI, NFS,...).
Multihop FCoE is what you are going for ?

Hi Walter ,
Thanks !
1. We have FC and also FCoE storage
2. Question : I see on the n5k this output [while checking few things i saw it] :
"Vsan 1021 is down (Vlan not FCoE Enabled)"
What does it means ? what should I do ?

Thanks anyway .
I'll keep going, and will see if I'll have some more questions .
