Hotspare vs. Hotswap

What is the difference between hotspare and hotswap?

Hotswap is the capability to replace a failed part with a spare without having to shut down the system. To resolve a problem, somebody still has to bring the spare part and do the actual work replacing it.

Hot spare is the spare part that is placed into the system at build time, in anticipation that something will eventually fail. The hot spare ties the part which could be otherwise used, but instead sits idly waiting for something to fail. On the bright side, when something fails, there is no need for a human intervention because the spare part is already there and ready.
