If you have several Dell servers (or even just one server) then I would highly recommend downloading the Systems Management Dell DVD. Inserting this DVD in the server drive will then show you a list of all the firmware, drivers and software that needs to be updated on the server. This is a great tool for ensuring that your Dell server is up to date and you don't need to download all the patches each time on the server or even worry about where they are located on the Dell website. I find it really difficult to work out which files are needed and this DVD is really helpful. Included on the DVD is the OpenManage 5.3 suite of software that came out fairly recently. Note that if you install it then you will want to go back to the alerts page as there maybe new alert categories.
I know IBM do a similar service as I used to use it when installing Netfinity servers and I assume HP does too.
Incidentally I found out about this by subscribing to the Dell Technical Update Subscriptions
