Some things to consider: - Hardware
I prefer fast SCSI disks with RAID-1 redundancy. 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.
