I don't think the different PSU would be an issue, The supply you've linked doesn't seem to care about linking grounds together. > or even more reliable would be a PicoPSU w/ a hack to make sure that the > power is always on. > > Has anyone tried something like this?

I hacked up a PicoPSU for robotics use (running off +24V and providing +5/+3.3); your "always-on" should be as easy as shorting the green-black wires (short Pin 14 to ground) with a little solder jumper. But wouldn't you need some type of reset trigger for when the system is reset? Or is that performed by the SATA controller? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
