First, I attempt to not recommend single products. You are the purchaser. You are the one who will foot the bill and must be satisfied with the results. You are also the one who is supposed to be most informed on your circumstances and requirements.

Instead I attempt to point out alternatives or correct misunderstandings and oversights in thinking. Along these lines, let me apologize in advance if some of my comments seem harsh. They are not meant to be unkind, but rather are intended to get you thinking on the correct plane.

The best starting place is always the beginning. I have followed several of your posts and it is unclear to me whether you have established and researched the basic premises of your system.

What exactly is your budget? What is the system's primary use? Will the system be used for other tasks? How much of your budget will be for HW and how much for SW? The one thing you appear sure of is that you will be running some kind of trading program. What are the resource requirements of this program?

After determining your budget, this is the next thing you must research thoroughly. You are foolish attempting to select system components without a complete understanding of these requirements. I also have no knowledge of this type of application.

For instance: what is the preferred OS for this app? Does it usually require use of multiple Virtual Machines (VM)? How much memory is required by the app? How much HD space?

I infer that you are getting some kind of stock data as input to your app. How is this input? Is it via a modem link? If so, does a very slow modem link require expensive SCSI HDs and even more expensive SCSI RAID? Or are you using and can afford a dedicated high speed link?

In this process you also need to check out various manufacturer and HW sites for yourself. They contain some excellent material and your informed decisions are much better than acting solely on someone else's opinions. It would take too much space to echo this material in a post.

However, once you have communicated the basic parameters of your requirements, I would be happy to post some links that might assist informing you on specific areas.

I will hold off on replying on the specifics of your two posts until we have a better understanding of the above.
