Server+ terminology question. 2

[Ebizguy]

Can anyone explain the difference between the terms "Hot Plug" and "Hot Swap"?

Hot Swap means that you can remove the drive and replace it with another drive without significant interruption to the system

Hot Plug means that you can add a new drive easily, but you cannot do so without taking some sort of outage

I'm going to say the difference in the two is who you talk to:

http://en.wikipedia.org/wiki/Hot_swapping

and

Are perfect examples of what I mean. 2 different authors have 2 different meanings. glister may know what Comptia is looking for as far as the differences....

You'll typically see the term "hot swap" used in reference to SCSI systems - refers to the ability to remove a failed member of a redundant disk array and replace it with a good drive without bringing down the server or interrupting transactions that involve other devices. Most modern hot-swap methods rely on a specialized connector with staggered pins. Most staggered pin designs have the ground pins longer than all the other pins. This ensures that any sensitive circuitry is never connected before there is a reliable system ground. The SCA-80 SCSI Connector is one such connector.

You'll see "hot plug" refered to USB devices - The ability to add and remove devices to a computer while the computer is running and have the operating system automatically recognize the change. Two new external bus standards -- Universal Serial Bus (USB ) and IEEE 1394 -- support hot plugging. This is also a feature of PCMCIA.

You will sometimes hear the terms used interchagably.
