Sadly, the most common configuration around here seems to be this: 64-bit Ubuntu with a 2TB SATA disk (ext4) and 4GB of RAM. When it breaks, hire the high-school kid who installed it so he can use 'google' to 'fix' it. Realize you don't have any backups. Send all employees home for 3 days. Hire ultra-expensive know-nothing IT contractor. Replace Linux server with Windows and start data re-entry project. Wait for the first 0-Day to wipe out your biz. Repeat annually. Joking aside... The most common Enterprise Linux configuration I've seen is: RHEL/CentOS, RAID 5 with SATA/SAS disks, 8GB RAM, ext3. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
