Need help with: Hot-swappable, Hot-pluggable
Company is putting together a server and we have conflicting opinions on what these terms entail. Its no surprise since everyone and their dog is PLASTERING these buzzwords on every server product known to man without explaining how it works.
Could somebody give me a precise definition, and whether these terms are different, or are just two buzzwords that mean the same thing?
You see, Ive always been under the impression that hot-swappable devices are just that: capable of being added or removed from a device while that device is powered-on.
Example: PCMCIA and USB are hot-swappable. This to me means you can add or remove devices anytime while the bus is powered, which YOU CAN.
My co-worker, on the other hand, INSISTS that hot-swappable DRIVES means that its a REDUNDANT system which, in the case that a drive fails, it AUTOMATICALLY re-configures an extra drive to replace it. To me this sounds like utter bull, since REDUNDANCY in my book is an whole different animal from HOT-SWAPPABLE. His description sounds like Mirroring to me. Who is right?
And what about HOT-PLUGGABLE? Ive heard that used to describe anything from powersupplies to drives, so in my mind this points to some obvious overstreching of the definition of this word.
Can someone shed some light on this confusion?
