Evolt currently runs on CF, Linux, Apache and Oracle and did about 2.4 million hits for March. It's certainly doable to scale that up to a site such as yours. As to the question of whether you *should* switch to Intel/Linux, well that's another question. Fundamentally, I'd trust the head tech guy because he's the one that who is going to be taking care of it. If he feels that he can do a better job running Linux/Intel rather than Solaris/Sparc, then he's probably going to do a better job running Linux/Intel. Specific recommendations I'd make: Keep one of the small Solaris boxes as a mail server. Mail will happily sit there and hum along with little or no intervention for a long time. And it usually runs just fine on "legacy" hardware. Qmail (the mail server I use) will process several hundred thousand messages a day on a P-90. To keep up with expected growth, start preparing yourself for a cluster configuration. That provides you with the most robust and easily scaled system configuration. But it also means training your tech folks and probably rewriting portions of your CF code. If you wanted a cheap ease-in solution, you could buy a new Intel box and stick CF and Apache on it and keep Sybase on your dual processor Solaris box. This would lessen the load on both machines and make it so you don't have to buy a new license for Sybase (an expensive proposition). Then you can add on new CF/Apache boxes as web load increases and eventually move the DB to a new beefier machine (say a 64 bit Intel processor). I think that you would have to get a new version of Sybase if you wanted to run it under Linux and its probably best to move as few pieces at a time as you can to avoid making mistakes. Put all web/db machines on a local 100/1000Mb network and you can ease yourself into a cluster configuration one machine at a time instead of committing whole hog and replacing everything. Also, I know that the next version of Cold Fusion is in beta so I would expect a new version to be out in the not so far future. This is the version that's rewritten from the ground up in Java so big changes are likely in order. You might want to wait and take a look at system requirements and performace specs for the new CF before you make a decision on what platform and machine to go with. It could have a pretty big impact on what your perceived needs are.
