I want to use NFS datastore with a netapp filer for virtualisation with ESX5
but I do not know how to estimate the necessary bandwidth for my infrastructure
I have 50 vms using a vfs of 2 X 1Gb ethernet nics for the nfs
thanks for your help

I am not quite sure what you are behind; But you can get the bandwith if you know the the IOPS and the IO size.(andwidth =IOPS*IO size)
The maximum you can get out of 2* 1Gbps line is around 2*110MB considering you have configured your NFS clients to make best use of both the interfaes. Remember that the bandwidth you get mostly depend on the io size and io type (sequential versus random) etc.
