We found lots of SAS Controller Reset and errors to SSD on our servers
(OpenSolaris 2008.05 and 2009.06 with third-party JBOD and X25-E). Whenever
there is an error, the MySQL insert takes more than 4 seconds. It was quite
scary.
Eventually our engineer disabled the Fault Management SMART Pooli
We finally resolved this issue by change LSI driver. For details, please refer
