How to determine the size of partition hard disk

[Shahliza]

I want to partition the server so that around 50 user can use the server as web hosting for servlet and JSP. so how big is the size of the partition such as ex3 or swap files.

Thanks for your help.

swap should at least be the size of your RAM.
The other partitions depend on your personal preferences. You can make just one big / partition, or you can make a /, a /boot, a /var, a /home partition, etc.
