Our organization has come up against a couple of problems when encrypting production servers. Using TruCrypt (our current favorite) we lose the ability to do remote reboots, absent a DRAC or iLO2, as well as the ability to do any automated, middle-of-the-night reboots for updates, etc. Also, the processing overhead for the constant encrypt-decrypt cycles is taking a toll. Is encrypting these servers worthwhile? If so, what's the best strategy to mitigate these problems?
