The following context is from the movie "Mission Impossible Rogue Nation"

This is a link to an excerpt from that movie. The phrase I've got problems with starts at 05:20 Simon Pegg says "All security data is stored in a liquid-cooled array"


These are 3 definitions I found for "array" on thefreedictionary that I think might be relevant here:

  1. An orderly, often imposing arrangement: an array of royal jewels.

  2. An impressively large number, as of persons or objects: an array of heavily armed

  3. An arrangement of usually identical devices, often sensors, that function as a unit: an array of solar panels.

    A liquid-cooled array is a physical structure. Searching for "array in computing" will lead you down the wrong path. Aug 1, 2022 at 15:48

    @Lambie - in computing an 'array' alone (not of some things like hard disks) is a data structure used in coding; like an integer, floating-point number, alphanumeric string [of characters] etc. I don't think the computing term is necessarily helpful. Tech talk in movies is notoriously rubbish. Aug 1, 2022 at 15:50

    It's probably a reference to RAID (redundant array of independent disks) storage. Sloppy though, since although processors might be "liquid cooled", RAID hard drives (or SSD's) wouldn't normally be treated like that. It's just a movie, so technical accuracy isn't important anyway.

    Look at the clip. You can "see it".

Your third definition is correct. As @FumbleFingers mentioned, it's almost certainly a reference to a RAID or RAID-like setup. While the hard drives in a RAID setup do not have to be arranged in any specific physical configuration, they are strictly arranged in a logical configuration. There are several RAID configurations, but one configuration is multiple storage units (hard drives, for example), each one being an exact duplicate of the others. If one hard drive fails completely, no data is lost. This makes some sense because if the information is so valuable that it requires the complicated security system surrounding it, it also makes sense that the owner of the information would like to provide redundancy in case a single storage module fails. This is also a mild example of "technobabble", which is common in science fiction (such as the "flux capacitor" in Back to The Future).

  • +1 for "technobabble." Google returns 38 matches for "liquid-cooled array" (not 378 as it first indicates) and many of them lead back to Mission Impossible. So it's kind of a thing, but not really. Aug 1, 2022 at 16:47
