I have Norco-4220 right now with 20Hdd's in it. I want to expand my raid array (currently two arrays on one 1880 right now, 12 drive and 8 drive both raid 6). At the same time I want to ditch the crappy 2U case my HTPC uses. I was thinking about the Norco 4116 for the HTPC and using 12 of the hot swap bays for my 12 drive array, but connected back to the 4220. I know I can do this using my SAS expander and external ports, my issue is how could I power the drives if they are in another chassis? I want them to come off and on with the server, not with the HTPC.

Ideally my server PSU would power the 12 drives in the 4116, but unless there are special accessories for this trying to fish power wires between two sharp edged metal cases seems like a bad idea.

Any thoughts?
 
See the DIY JBOD Storage Chassis post.

You probably want to power the second chassis using a second power supply because running that many drives form one PSU is scary, and external power connections for that many drives can be rough. Plus you need to power the SAS expander anyway.

pjkenned: did you ever solve the problem of remote-triggering the storage server PSU in the 2nd chassis? The last time this showed up in a thread here on [H] there was talk of a relay-based trigger method. Did you ever try anything like that?
 
No real progress on this front. I basically realized that the main server was up 90 days at a time, then patched, then back online. It became easier to just leave the box on 24x7. No logic is running, and everything is hot-swap capable (now that it has a redundant PSU) so there is no reason to take the thing down, especially now that it runs off two UPSes.
 
So how would I do dual PSU's in one case and if so how do I use the 2nd PSU without a mobo, switch, pwr switch.
