planning

can anyone give me a hint about how to plan for the future with an informix database, i work on applications that are on the web doing user authentication and soon to be accessed anywhere from 50-250 million times a day. i'm running on a sun enterprise 4000 with 8 cpus (though informix is affinity'd to 6) with a gig of memory, the database itself is only about 4 gig. management wants to know if this machine will last us for the next few years. i don't know where to start! tia! -- _^..^_ _^..^_ =\\ "/= =\\ "/= email - kadkins@gte.net / | | / | | / )| || / )| || _ ( __\\...) _( __\\...) \\ \\ (_) homepage - http://www.geocities.com/~kkitten
