Can you give > us any more details? sure, it's a unique accounting application geared toward the custom hardware industry (i.e. high-end sinks, door knobs, towel warmers, yes, towel warmers, etc.) so it's a vertical market that is in dire need of something geared for them rather then what's currently out there: hobbling legacy systems. rather then use the traditional onsite installation business model, i will be setting up as an Application Service Provider. I am writing my app with a three-tier architecture, but i haven't decided whether the mid-logic tier will sit on my servers or on the client side. (it's much more network intensive on the server side) anyway i essentially need database servers, each able to handle anywhere from 10 to approx. 300 concurrent users. i project to have a client base of 10,000 cuncurrent users split into groups ranging from 10 to 1000, each group needing to access the same database. so i may end up with an installation of 1000 units! some basic hopes for each machine: IDE ATA/100 RAID 5 with easy access to drives, power redundency, and low power consumption. today i have actually been looking at transmeta's developer board, and considering if i could throw it into my own rackmount chassis and use it! but damn its hard to find a good 2U microatx rackmount case. p.s. FYI - the plan, once this thing gets off the ground, is to hire a ruby programmer (i am dead beat of doing everything myself :-) -- ~transami
