The one thing, and you have no real control over it, that I've noted is the
use of the 'find' command. Obviously this can randomly work the processors
hard. If you think there's a risk of heavy use of that then chuck in
processing (and memory - it's so cheap). Likely though you can't as you'll
be at the hardware limit on processors.

Subject: RE: Server memory?


It really depends on how your users are using it, how heavily do they use
it, any forms or scripting, attachment traffic etc. etc.  But for the amount
of users you talk about you should be just fine.

We use Compaq ML570s with quad PIII700s with 2GB of RAM as dedicated mailbox
servers and I was able to load up to 2500 users on one without any issues
(although we try to keep it around 1400 users normally).

On another note, the "M$" joke is so old, so lame, and so boring.

Subject: Server memory?


Does anyone have an idea of miminum memory requirements for exchange servers
based on number of mailboxes etc? I have read the paper from M$ on this and
can only find reference to monitoring swapfile usage. 
I only have one server now (5.5 sp4 on win2K) but we have just taken over
another company thus giving me an extra 200 mailboxes. My server is a HP
dual Xeon 700, 1 gig of RAM and plenty of disk (90 gig on raid 5) SHould
this cope OK with 6 or 7 hunderd users or should I get another server to
remove some of the load? Ideally, if I can make this one box do it all
(except IMS which is relayed from an IIS machine in the DMZ) I would prefer
this option even if it means adding memory. Is there a "rule of thumb
amount" of memory per mailbox i should be looking to have? Thanks Dominic.
