Server compatibility?

Hey there,
i would like to purchase a second server and set it up as a mirror server.
But now im wondering if all the servers are compatible.
I got the Drobo 5N, would it still work if i purchased a 5N2?

Good Morning and sorry for the late response, not all Drobo Devices are compatible but the 5n and 5n2 can be mirrored, Please take a look at the following links before making a purchase on any other devices.
