he's talking about dell servers, hp and others have their own flavor or remote access boards. If you have used one you know how powerful the devices are. I would like to see the device hardware lists for servers used.
Many dell servers have Dell Remote Access Controllers (iDRAC)
The iDRAC is a piece of hardware that sits on the server motherboard that allows Systems Administrators to update and manage Dell systems, even when the server is turned off.
The iDRAC also provides both a web interface and command line interface that allows administrators to perform remote management tasks. Almost all current Dell servers have the option for an iDRAC.
