Nowadays you can get a petabyte in a single machine (50 drives 20TB each).

Out of curiosity, what server cases can actually accommodate 50 drives?

  If you google "supermicro 72 drive server" it's definitely a thing that exists, but these use double-length drive trays where each tray contains two drives. Meaning that you need a "whole machine can go down" software architecture of redundancy at a very large scale to make these useful, since pulling one tray to replace a drive will take two drives offline. More realistically the normal version of the same supermicro chassis which has 1 drive per tray is 36 drives in 1 server. There are other less publicly well known things with 72 to 96 drive trays in a single 'server' which are manufactured by taiwanese OEMs for large scale operators. The supermicro is just the best visual example I can think of right now with a well laid out marketing webpage. edit: some photos https://www.servethehome.com/supermicro-ssg-6047r-e1r72l-72x-35-drive-4u-storage-server-released/ https://www.servethehome.com/supermicro-ssg-6047r-e1r72l-72x...

      You don't LEGO assemble rackmount servers. Chassis come with figurative array of jet engines with 12V/0.84A -ish fans that generate characteristic ecstatic harmony. They're designed, supposedly, to take 35C air to keep drives in front at 40C and GPUs at back <95C.

  Those are specialized NAS chassis. We have a number of them, 4U size, too heavy to move when the drives are in. edit: They look like this: https://knowledgebase.45drives.com/wp-content/uploads/2019/04/20190405_163715-1024x768.jpg https://knowledgebase.45drives.com/wp-content/uploads/2019/0...

  iStarUSA are my go-to for my whitebox server builds, and they sell a 9U 50-drive hot-swap enclosure: https://www.istarusa.com/en/istarusa/products.php?model=E9M50 https://www.istarusa.com/en/istarusa/products.php?model=E9M5...

  aic j4108 for 108 drives. Not a server per se, but you just take one 1U server and daisy chain a lot of those JBOD chassis for the needed capacity. You can have 1080 disks in a 42" rack.
