We've got the "AMP" part of LAMP down pretty good, and are now looking to colocate our own server running Linux. We are looking for a Linux distro that can scale well for multiple server growth (future), is rock solid, and configures well with memcache, load balancer, firewall etc. A free distro would be ideal, but if the Slashdot community recommends a Linux distro that is not free, that is fine as well, since our minds are open to grow with the right distro. I've done some searching on linux, but that is not yielding the fruit I am looking for. Our first goal would be to run it (learn it) as a localhost and configure it with Plesk or similar, to get ready for the real thing."
