I just got an HP Proliant DL380 G5 server (it's actually Cisco branded, but I don't think that matters), without the rack rails. I'm trying to learn some server architecture and use it as a basic server. I am looking for some rails to mount it in my rack.
What are the differences of the rails between generations? I see a lot of G6 rails with the cable management arm for sale; is it backward compatible with the G5? Or, do I need to seek out a G5 rail specifically?
If the differences are minor enough, could I simply mod the rails? (e.g. drill my own holes).
