Hi,
I've been thrown well and truly in the deep end at my work. I work at
an academy with about 300 employees and 500-600 students, and am about
to become the IT Manager (and I have no experience of a job of this
magnitude).

Anyhow here is what I am looking at providing with a linux solution.
There will be at most 300 employees logging on to the system and the
students wont have access, except where noted below.

* Primary Domain Server (SAMBA for Windows XP Pro clients)
* NFS (SAMBA again. I estimate serving a max of 5GB, not anticipating
huge amounts of transfers)
* Mail (IMAP preferred)
* Web Proxy (may also include access for cadets perhaps through 50
terminals)
* Address Book (LDAP)
* Printers Server (SAMBA again I'm guessing)
* Web Server (the most significant component is an online database for
cadets (already in existence using LAMP, and examination system using
Moodle)

* Application Server (not sure about this one, looking at it for virus
scanner update)

So what I am thinking is three servers.
One as NFS/PDS
One as Mail, Address Book, Printer (and backup of the above)
One as Web Proxy, Web Server, firewall

How does this look as far as distributing load. I was considering
putting PDS and NFS on different boxes as I think these might be the
two highest demands....

I wont have access to, or a budget for, high end server boxes.
Instead I will be looking at buying more or less standard intel boxes,
heaps of RAM and RAID 0+1 setups. What system specs should I
realistically be looking at to achieve my goals? How would you
implement this if it were you?

Many thanks,
Damo
