I haven’t worked in a data center in years, so I don’t know the current norm for server hardware.

The Dell servers we had at the time all had slim laptop style CD trays, so no auto-close to worry about.

This command was very useful for quickly finding a server in a row of hundreds of identical servers. No need to read the labels or look up which rack it’s in. Just log in remotely, just use ‘eject’, and then walk down the row to the server that has its tray out.
