Hardware requirements IIS

[Mare]

I'm having difficulties planning hardware requirements for IIS 5 running on
WIN 2000.

There will be 400 active users using the sistem (intranet / transactional
sistem). I don't know how many hits per second this is?

Processor ?? MHz ??
How many Mb of RAM?
Disk space?

I'm, familiar with the minimuim requirements for IIS, but have no idea about
the performance with this number of users.

The application logic and a database will be on a separate server.

Thank you for any comments ...

There's the key, the number of transactions hitting the box. You
could have ten thousand users who never hit the box or a dozen who hog
all the resources.

Then all you really need is bandwidth processing, if what you say is
actually correct.

That said, for a professional use box, there's no reason not to do
dual processors in the 1 GHz and up range, RAID5 with at least 5 18GB
Drives and maxing the RAM (2 GB +). Make sure you have adequate
backup, and high bandwidth networking wouldn't hurt. For true
redundancy, a cluster might be in order, but it's unlikely you'll
experience any performance issues that would require one.
