Does anyone have any suggestions for a NAS RAID that automatically turns on when power is restored following a power failure? Looking for 2+ TB, and rack mount is probably best, but desktop is fine if it meets this one sticky item. We have systems in the field that often see power failures well in excess of UPS capabilities, so we need something that will turn itself on. Not sure how to handle the soft shutdown part either to ensure no data loss, so if anyone has ideas there as well I would appreciate it.

Thanks,

Hm normal computers have a BIOS setting that controls what the system does after a power failure, either it will power up again or keep powered down until you press the button. On a retail NAS it would totally depend on its features and design. So as an alternative, a small pc would be able to power up, and could be made from commonly available hardware.

The shutdown part is triggered by the UPS. Once the UPS is getting into critical battery range, a signal to the PC will order it to shutdown. For this to work, often driver-software from the UPS manufacturer is necessary, or linux/unix which have built-in drivers for a limited range of models. Normally a USB cable would act as data interface between UPS and PC, old systems use a serial cable (with 9 pins; or RS-232).

A dedicated computer would work, but I really need a simple as possible COTS solution. Building something isn't an option in the environment in which I work. I know the COTS NAS arrays are generally just embedded Linux or XP type boxes, so somehow I would suspect there must be some that could support such a setup, but maybe I am dreaming.
