How do 8 x N7K physically connect?

[Maivakov]

why not or can 8 x N7K combined to become one N7K with VPC?

Is there limit in combine ? I find people only combine two in one but not all N7K in one.

routing among VLAN gateway, each N7K have different VLAN gateway , can each pair choose one of two to use cable to connect as mesh ? Because the other one of two look like no connection to mesh. In other words, all 8 x N7K in full mesh ? Or just choose one of two 4 x N7K in fully mesh , so the rest one only use peer link to the one connected to mesh?

or should 8 different VLAN gateway configuration should configure at all 8 x N7K at the same time?

From CISCO you can only combined two nexus in one vPC not more. 

If you have 8 then combined each two to form one vPC and then interconnect the four VPC pairs to build networks. 

Each host connect to one vPC pair have it GW.

How about OSPF routing among VLAN gateway after configured each two as VPC

2xnsk form 1xvpc which have hsrp 1xVIP for specific subnet 

Host connect to this vPC use 1xVIP

8xnsk interconnect using 8xSVI.
