Thank you Howie, We're planning on using something like this on all 3 servers: ProLiant DL580 R02 Xeon MP 2.8GHz-2MB, 2xCPU 2GB MEM with 15krpm SCSII disks. This server can be upgraded to 4xCPU and 16GB Mem
Overkill? What about disk space reqs and bandwidth reqs for this number of users - is there any good formulas to find the numbers?

For applications that read/write a lot of files (a mail server is a good example of this) you don't usually want the overhead of RAID-5 (although some newer RADI-5 systems are much faster than older RAID-5 setups). I would also choose a RAID card with a good amount of read/write cache. As for memory/cpu I would recommend dual CPUs and 1GB RAM (RAM is relatively cheap nowadays). - Software A single iMS Enterprise server should be sufficient for a long time. However, later on you can always utilize redundant servers for mail sending/receiving. We will also be making improvments to iMS in regards to the outbound queue and possibly better load balancing capabilities which will make things even better for a setup like yours.

I'm currently in the process of specifying a server setup for a potential customer. This setup is a bit new to me and I hope to get valuable advice from you - I guess my needs is not very uncommon for some of you - In Norway this is a LARGE setup... (the biggest company in Norway has around 30 000 employees - and there is only a handful with above 20 000 employees) The customer needs a system that grows over time - and I need some hints on what hardware / licenses to start with - so that the upgrade to more users is as easy and cost effective as possible. The setup will be: Dedicated iMS server with ColdFusion professional (pop3/smtp, antivirus and different filters, lists, autoresponders etc) Dedicated MSSQL 2000 server Dedicated CFMX/IIS web server(s) with CMS / portal including web mail (there will be lots of additional modules on this portal - and it will work towards the same DB as iMS) Starting with 10Mbps internet access (shared with our other systems - average usage today is below 1Mbps) iMS Enterprise with PrismAV (to be purchased after customer accept on offer (hint :-)) The email accts need pricing and sufficient hardware/software in the following steps: <500 accounts 500-1500 accounts 1500-5000 accounts 5000-10000 accounts >10000 accounts (I guess we'll reach 5000+ accounts after about 2 years) So - is there any "golden rule" on how to determine the needs for processing power / storage space / DB power? Growing from <500 - <10000 accounts is probably not a thing to do on the same hardware - but what power should we start with - where would we need to upgrade to better servers - and how much storage and processing power is needed with say 15 000 email accounts.
