I am looking at going the Hyper -V R2 route. I will be using 2 Dell Power Edge R710 with Xeon 5600 processors *2 and 100 Gb Ram. Both servers will be connecting to a SAN – PowerVault MD3000 from Dell. They will be clustered for fail over purposes.
Now for DR solution to work I would like to look at a continuous backup solution – At present we are using storage craft for our Servers (not in a Hyper V solution) We are getting Snap Shots every hour and management are happy with an hour loss.
