This isn't the only problem that SnOracle has had with the X25s. We managed to
reproduce a problem with the SSDs as ZIL on an x4250. An I/O error of some sort
caused a retryable write error ... which brought throughput to 0 as if a PCI
bus reset had occurred.
Here's a sample of our output... you might want to check and see if you're
getting similar errors.

We were lucky to catch the problem before we went live. There were an
exceptionally large number of I/O errors
Sun has not gotten back to me with a resolution for this problem yet, but they
were able to reproduce the issue.
