>>16365 that's nothing!
I took some vitamin C earlier. I've been drinking tea all day, and now wine, for that 1-2 punch.
It's not really a server thing; just a computer thing. It uses mechanical disk drives because SSDs will write themselves to death in servers. In the 0+1 configuration, 4 nearly identical drives are split into 2 sets of 2, and each half of the set of 2 gets half the data, so they write and read twice as fast, and the pair is mirrored so the whole thing has a backup if any one drive fails.
they actually paid me for all the other stuff I did. took them a while. had to go back and forth with them half a dozen times, and then they lost the paperwork, but eventually it got straightened out. and now I have new stuff to work on for them.
