Most large sites use clusters of systems rather than a small number of = overpowered servers. If I recall correctly, most of Yahoo's systems = are P-II class workstation boards. If you're looking to build higher-end servers, I can recommend systems based on the Intel AD450NX and SC450NX chassis or their descendants and replacements. If you want to build a small cluster of high-powered nodes, you should look closely at the AMD K7/700 and the Compaq Alpha-based systems such as the single-processor DS20. -- = \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
