How to configure an iStack Ring topology?

HI,

The 4 switches are in two buildings, you need to use fiber to connect them. it‘s better to use the same link bandwidth in stack connection.DAC or fiber are the same.

Thanks for that.

At this stage I don't have enough fibre cores for 4 connections between the buidings (unless I change to bidi sfps).

Will it be a big problem if I only have a single fibre between the two switches? If I do that am I better to change to a "chain topology"?

ring topology is better ，if the quantity of the switch is more than 2.

there are only 2 connections between the two buidings , it is ok ，the bandwidth is only 10GE.

I think its better to establish 2 stack system ,in different building, only my suggestion.
