I've have had a lot of issues with the 9650SE range of cards.

Intermittent dropping the card from the machines (the card completely disappears), very weird reporting on disk spindle speed's detected etc. They haven't been a very reliable card once we had the SANS with a fair bit of load on them the 9650's just seemed to die.

We changes to LSI Megaraid cards and haven't looked back. (Both my SANS I just noticed coming up on 248 days uptime, compared to the 30-60 days before I'm very happy).

I tried to deal with 3ware, supermicro (my mainboard) and went around and around in circles, each blaming each other, but no one wanting to solve the problem. I did move to a beta firmware that seemed to hold up better, but still couldn't trust the cards after having a 60+ machine VM Cloud go down several times, the only company that stood by me and supported me trying to work through these issues was open-e.
