I noticed that StackExchange/ServerFault is using a Dell R710 with PERC H700 controller and Intel X25-E SSDs for a database server. We're trying to do the same thing!
We're currently running the most current PERC firmware, version 12.10.1 (which unfortunately is several releases behind the equivalent LSI firmware). The Intel X25-E SSDs run beautifully in all respects--configuration, performance, etc.
What we're seeing is two effects--about two minutes after a reboot, the disk status lights permanently turn from green to blinking amber, and at the same time, the hardware management log gets a non-critical error with "A non-Dell supplied disk drive has been detected". These seem to be more of a nuisance than anything else.
At this point I'm about ready to get some tape and cover the lights. So my question to the StackExchange/ServerFault folks (or anybody else) is whether they ran into anything similar.
