I happen to visit several data centers with two different scenarios:
I've seen that some of them have an ISL and some not. One fabric with two ISL´d switches or two separated fabrics.
If they ask me I'd prefer to have them separated. In that way we have a real redundant configuration even though I have to work twice when making any kind of change. But, for example, updating firmware would be an ease task to do since the other fabric would n´t be affected by the process.
On the other hand, if anything happens to the fabric zoning database having two fabrics it would make a complete mess.
My question is... Is it better to merge those 2 fabrics or not? Perhaps any of you guys cant tell which way is the best or why.
