Dell's OpenManage Server Administrator is a powerful tool for keeping track of your server's health and making sure everything is running as it should. Unfortunately, Dell only released packages for RedHat and SuSE, so installing the software on Ubuntu can be tricky, at best.
There is some information on the Internet about getting the package to install on exotic distributions, but I never found anything definitive. This tutorial will guide you through installing the software and getting the web access up and running.
My setup is: Dell 2950 with 1 Intel 2.2GHz Processor, 2GB RAM, PERC 5/i SCSI Raid Controller with 2 73GB 15K RPM SAS disks running Ubuntu 8.04.2 LTS 64-bit.
