This is probably a long shot, but is it possible to cheaply turn an old server into a NAS used for VM backups?
I'm assuming the road map would be to buy the drives, install OpenNAS or some other NAS operating system and go from there. Problem is, i've only found guides geared towards home users converting their PC's.
I need the ability to create iScsi targets on this NAS to do backups from VMware. So that makes it a little more complicated. I know that's not a problem for modern proper NAS, but for a roll-you-own NAS?
Has anybody done this? Is it economical and flexible enough for business use, and something like VMware backups using iScsi?
