Revive old home server
After replacing the failing home server with a decent Synology NAS I got my hands on a HP Storageworks Data Vault X510.
Turns out it’s not too difficult.
-place the harddisk to install it on in a standard PC and use that to install the i386 version of Debian (in this case it was Jessie)
-add a fixed IP address for eth0 in /etc/networking/interfaces (the Realtek r8168 (seen as r8169) couldn’t get a DHCP address for some reason)
-place the disk in the X510 and boot
-login with SSH (you did install it, didn’t you?)
-have fun with it
