About 17-18 years ago (during my first year at university, 1989-1990) I bought a PC with a 12MHz (I think) 80286 processor, 1MB of RAM, and 40MB of HD. As of a few days ago I have this in one of the headless servers in our basement:
$ df -h /dev/md[0-9] Filesystem Size Used Avail Use% Mounted on /dev/md3 9.4G 2.9G 6.1G 33% / /dev/md2 99M 35M 60M 37% /boot /dev/md4 965M 18M 899M 2% /tmp /dev/md5 176G 158G 9.0G 95% /var /dev/md0 276G 226G 51G 82% /mnt/media /dev/md1 459G 267G 169G 62% /mnt/backup
People that have worked with Linux before will recognize the /dev/md* devices which are typically used for RAID setups. In this case they’re all RAID1 (mirrored) setups, with two 200GB, two 300GB and two 500GB disks underneath this, so 1TB of redundant storage.
That’ll keep us going for a while, I think.
