I've had a very good experience using UltraMonkey to run a HA and LB web farm. They just came out with a new version that no longer requires custom kernels for modern linux distros. www.ultramonkey.org.
I store all the web content on a NetApp and NFS mount it to the web servers. httpd configs are generated and rsynced from a master server to each web server using Makefiles. --[Lance] -- Celebrate The Circle: http://www.celebratethecircle.org/ Carolina Spirit Quest: http://www.carolinaspiritquest.org/ My LiveJournal: http://www.livejournal.com/users/labrown/ GPG Fingerprint: 409B A409 A38D 92BF 15D9 6EEE 9A82 F2AC 69AC 07B9 -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
