MJ, your description is a little unclear but what you want to do is estimate how many IO per second you need to handle and then spec the hardware especially the disk farm to be able to handle the load. The number of concurrent sessions is very important for determining the server specifications: number cpu and memory.
Being that I work for HP I will recommend that you look over our offerings. If you want Intel base X86 processors we have the DL380 line which is pretty good and we also have Itanium based product. We also offer storage solutions and network switches. We can provide the complete package which can make our solutions very cost effective. Just visit our web site.
But to get truely useful sizing help you need to determine your IO requirements and concurrent user load. You will also need your total storage requirements. With this you can make informed decisions. Without decent estimates you might as well just buy as much hardware as you can afford. Once you have this information you can contact various vendors and ask them to submit bids with appropriate equipment to meet your performance specifications.
