Im of the opinion that you best get this out sourced. The fact that you asking hardware questions, and the tone and way you describe it, tells me, you already knee deep in the s%^t, and you lack the experience. Theres a lot more than just picking hardware and what software you gonna use. Lets use raid as an example and some questions : Will it be hardware or software raid (hopefully hardware, and will add to the price). How does the OS work with the raid? What filesystem will work or best suited on the raid Do you know how to work with the raid? It you talking clusters. How well do you know CARP (FreeBSD) or use heartbeat and all the other technologies. What about catering for redundancy (in its other various forms), something silly as a power supply. It all depends on how serious you are about this, and what your real requirements (and there generally is more than you actually realise), its not a case of just buy a machine that was specced by one of the other list users and away you go. Im sorry to tell you this, but it looks like you tasked with learning on the job, and it could backfire. As said, best get / hire some reputable company or person to do this for you. The fact that you talking '1000 concurrent connections' and its a for a business, means the company can and / or should pay for it to be done right. Im not saying you cant do the work, but are you able to fully support it. HTH and good luck in what ever way you choose.
