Luca,
In my testing I have had better throughput with RAID 10 (at least with
XFS). I have not worried about the log files so much, so you might want
to investigate that some. I would love to see benchmarks of your SAS
array though. If you have a blog you should publish them if at all
possible. I used iozone for raw throughput testing and then the
querybench program (http://www.paragon-cs.com/queryprogs) to perform
testing with production data against the server.
Hope that helps.

Hi,
I have to install a mysql server for managing several database, from small to
quite big (tables with about 2M rows). I've got a SAS disk array and I was
wondering what the best configuration could be:
1) raid 10
2) raid 5
3) a combination (e.g., raid10 for the data and raid 5 for the logs).
Any suggestion or link?
Thanks,
Luca
