Ive been playing around with the Celerra Uber for the last few weeks with the following setup:

2GB Ram

x1 CPU (2 cores)

x1 Data mover

x1 Management NIC (eth0)

X1 Storage NIC (eth1 - cge0)

Ive now upgraded my test box so I can afford to give it some more RAM and enable x2 Data movers. So I set off building some more VM's with the following setup:

4.1GB Ram

x1 CPU (4 cores)

x2 Data movers

x1 Management NIC (eth0)

X1 Storage NIC (eth1 - cge0)

The question I have is if I have server_2 (DM1) as primary & then server_3 (DM2) as fail over, should I add another NIC for server_3 and give this its own networking? As well as looking to get this working Im also looking for best practise here.

Also can I increase / decrease RAM after the setup wizard has completed or will this cause issues?

Thanks
