From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What is the largest file transfer you have ever done? (startrek.website)

I'm writing a program that wraps around dd to try and warn you if you are doing anything stupid. I have thus been giving the man page a good read. While doing this, I noticed that dd supported all the way up to Quettabytes, a unit orders of magnitude larger than all the data on the entire internet.

This has caused me to wonder what the largest storage operation you guys have done. I've taken a couple images of hard drives that were a single terabyte large, but I was wondering if the sysadmins among you have had to do something with e.g a giant RAID 10 array.

I work in cinema content so hysterical laughter

Interesting! Could you give some numbers? And what do you use to move the files? If you can disclose obvs

A small dcp is around 500gb. But that's like basic film shizz, 2d, 5.1 audio. For comparison, the 3D deadpool 2 teaser was 10gb.

Aspera's commonly used for transmission due to the way it multiplexes. It's the same protocolling behind Netflix and other streamers, although we don't have to worry about preloading chunks.

My laughter is mostly because we're transmitting to a couple thousand clients at once, so even with a small dcp thats around a PB dropped without blinking

Eh, what's a dcp?

Digital Cinema Package; basically the movie file you're watching when you're in a movie theater.

Digital Cinema Package. Films come out in a buncha files that rather resemble a dvd rip. You got your video files (still called reels!) and your audio files, maybe some subtitle files and other bits and pieces and your assetmap (list of files) all in a big fat folder collectively called a DCP

That article was a weird mix of insider info and wild inaccuracies
