We have Netapp NFS server. Do you recommend round robin with 3 Ip's on the DNS? Please advise?
Technically you can.
Why for and why 3? seems like an odd number.
As Alun mentioned, technically you can, however your post contains very little information about your setup and why you would want to use DNS round-robin at all.
If you could elaborate on your situation, we should be able to supply a more founded answer.
