I have hibernated UV on linux and also suspended a VM running UV/linux and even hibernated the VM server running the client running UV with no issues - but this is a single user dev system. I would be very cautious of putting a production system to something not explicitly supported by Rocket - but by necessity it may be worth looking into. It may solve your situation nicely and if you do a properly managed clean reboot the next morning you'd probably be in pretty good shape.
You could do a simple smoke test - download a copy of the PE edition of UV to a PC, run up a few sessions (up to 2 or 10 with device licencing on PE?) running a program doing logged read/writes (I'd try a few different types of R/W readu, readv, sequential, transaction bounded etc) and hibernate and wake it and see if you get any issues. Let us know how you go.

Does it work and resume locally logged on sessions properly when the server is brought back up again? Obviously all network sessions will be aborted, but I'm not concerned about that. For background: We're running Universe 10.2.10 on Windows 2003 Enterprise X64 Server. Every night we have backups, a lot of batch update jobs and reporting that runs on the UV server. During this time period, there are no users connected to the system; only administrators can connect. Last week one night we had a power failure that outlasted the 4 hours run-time we have on our UPS, resulting in the server going down without a proper shutdown; fortunately not while in the middle of doing updates. I am concerned that something similar might happen while the system is processing; during the day it is OK as there are IT staff on-site that can make sure that user sessions are terminated as normally as possible and the server brought down gracefully during long-running outages. Why I'm asking about the hibernation: If there are local UV processes running, and the server is suspended to disk, will such processes carry on from where they left off when the server is brought up again ? - this could save us a lot of recovery time in such cases - rare as they are. Currently we have to look at at what point of the nightly jobs the server went down; if it was during backups no processing would be done; if it was during processing, we have to restore the backup to get the server back to a "known" state and so on.
