Hi Guys,

We've got an article up looking at performance of CFQ, Deadline, and NOOP IO schedulers with Ceph on the SAS2208. I won't claim that these results are universally applicable to other controllers and disk setups, but they might be interesting if you've been trying to determine what scheduler to use with your setup.

Thanks,
Mark
