In our case, we just make a little partition 2x RAM for swapping, and what remains will be used for the whole system.

Feel free to use the recommendation you want depending on your IT architecture; use your own judgment here or ask your IT manager. After finishing the partitioning task, you will be asked to enter the username and password; you can choose what you want except admin and zimbra.
