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.
My Chia crypto farm at its peak had about 1.5 PB of plots, each plot was I think about 100ish gigs? I’d plot them on a dedicated machine and then move them to storage for farming. I think I’d move around 10TB per night.
It was done with a combination of powershell and bash scripts on Windows, Linux, and the built in Windows Services for Linux.
