The 2nd time, even if RAID 5 status was optimal, it did not handle the loss of one hard-disk. We have a bunch of PowerEdge 1950/2950 running CentOS 5.6. No specific problem since the upgrade (I though about an issue with Squid, but no link with the fact that I upgraded to 5.6). If you have the LCD screen orange, this is an hardware-related issue. Some of them can be prevented/fixed by upgrading firmwares. You can easily upgrade from CentOS using Dell Server Update Utility or Dell Linux Hardware repository.
