Hardware Configuration - Need Advice

We have a web app currently being hosted on a RAID 5 with four disks, 2 GB
RAM, Xenon 3.2 processor. Also running Windows 2003 Server Standard Ed. and
SQL Server 2000 Standard Edition. Our database is about 4GB and at most we
have 10 concurrent users hitting our server, with a mix of read and write
operations. Both the OS and our DB are on the same machine. I am aware tha
t
having both IIS and SQL Server on the same box is not the ideal
configuration, but it has suited our needs given the load.
We are looking to private license our software to one other company, which
would entail the licensee having their own seperate db, but running in the
same instance of SQL Server. At a minimum, I'm thinking we would move SQL
Server onto its own dedicated machine, keeping the current RAID 5 config.
Perhaps this would not be sufficient?
What I'm looking for is some indication as to whether or not the proposed
platform could handle an increased user load, say 20 times what is now (200
concurrent users). This is primarily an OLTP db used for ACH processing,
with several reporting features. I'm fully aware that the application desig
n
itself, along with query tuning, indexing, etc is equally important as the
hardware, but need some guidance on the hardware itself.
What I'm looking for are some general guidelines to follow given this
scenario. Thanks in advance.Eric there is no way to answer that without knowing a lot more of what your
current system is doing and how the hardware is holding up now. Do you do 1
transaction per second or 1 thousand? What are the disk Queues, processor
queues etc. like now?
