I have a PD10000 for the firewall/server and haven't noticed a problem like that. I am planning to use an SP13000 for the CCTV machine in good time, but I don't like the sound of that reboot problem, are you running the latest BIOS etc?

I have configured software RAID too, is there any way to see if it's working without removing the server from the rack to disconnect the drive(s)?

Cheers

Cris.
