since i am scratching my head actually about an upcoming refresh of some datacenter infrastructure at a customer, i would be delighted to get some input about what others did.
We have two times 2x 5548 / some Fexes as TOR switches in two separated datacenters at a customer.
Since these have to be replaced somewhen, we are thinking about possible solutions which may fit best, customer doesn´t want to change cabling/layouts, but as i saw getting simply the "new nexus" seems to be no option anymore.
Customer still likes to have the features and reliability as well performance this solution gave him.
So, without further influencing, i would be absolutely interested in which way others went in that case.
