Our recovery interval is still set to zero, so I am unclear if we even have Indirect checkpoints working.

Increasing the recovery time will have what kind of impact? At this point its far more important to us to maximize throughput, than recovery time, but I suspect we may be having the 833 issues because of occasional I/O spikes (Occasional spurts of lots of updates being issued between checkpoints). Would using Indirect checkpoints “smooth out” the I/O?. Form what I’m seeing, changing the recovery from zero to some other number would cause less checkpoints. and greater I/O spikes during the checkpoints.

The SAN people are insisting it must be SQL server, because the dont see anything about the SAN or network having issues, but we believe its a SAN issue not being able to handle the spikes (possibly duirng checkpoints) I dont particularly care what is to blame, I am simply looking for a way to stop the 833′s – Would issuing more frequent, and therefore smaller checkpoints smooth out the I/O?

Would be interested to know case studies/projects where this would be used.

However, in the systems I work on, I don’t quite have a use-case where I see myself setting the “Target recovery time” value to anything other than the default (i.e. 0).

I would be interested to know of any case study or a hypothetical scenario where this can be useful. Also, @Pinal: I am looking forward to reading about the results of your workload oriented tests.

Thank-you!
