Top-of-rack definition?

    I have been doing some reading on blade servers and cloud computing and
    I continually come across the term top-of-rack. The term tends to use in
    conjunction with, what seem to be - to me anyway, monster equipment.

    Whilst I tend to have some form of self-defined placement in my racks
    for my core equipment and boundary equipment and so forth, I am kinda
    mystified by the top-of-rack term.

    For example, my main servers may sit in one rack and are usually
    arranged in some logical fashion according to utility. My routers may
    sit in another smaller rack. My switches may sit in yet another rack -
    with core switches in slots above distribution switches which are in
    turn above boundary switches, etc etc.

    I think I know what top-of-rack means but I am curious as to how others
    would define the term top-of-rack.

    My apologies for such a lame post from someone who probably should know
    better but then I never really went to computa skoool. The one day I did
    go, the teacher didn't turn up. :)

    Thanks Fred :) For a moment there, I thought the phrase was simply some
    clever marketing term designed to sound impressive :)

    Conceptually, it is as Parko's link suggest - it's a monster switch
    typically found at the top of the rack although Hedlund suggests that it
    could really sit anywhere in the rack.

    Again thanks for a good link :)
