This has got to be a FAQ by now. One can get by with one partition, using a
file for swapping. I think that would be a bad idea. Or one could use lots
of partitions as I do, which I think would be a terrible idea for most people.
One of my machines is like this (the other has far fewer partitions):

Why do you not try:
A swap partition -- often twice the size of your real RAM.
A / partition
A /home partition
A /var partition
A /tmp partition
A /srv partition where you will put sub directories for those servers
Depending on load, you may wish to use multiple SCSI drives so as to reduce
seek contention. No to replies to your query will give you the same layout.
