FalconStor and Oracle performance

I have a potential consulting gig involving a system that includes a FalconStor storage virtualization component. I'm not (yet) familiar with this company or its technology.

The database servers are RedHat Linux. RAID is supplied by a StorageTek array, and a FalconStor IPStor storage consolidation/virtualization box sits atop the StorageTek array. Apparently the StorageTek configures the disks as RAID 5, which we all know is a Bad Thing for database performance. However, the thing that puzzles me is a gradual deterioration in performance that can be corrected temporarily by rebooting the FalconStor box.

The application involves imaging, and the bulk of the activity is high-volume data loading (which makes the RAID 5 configuration an even worse choice).

I will, of course, be recording and analyzing wait events and statistics, but I'd also be grateful for comments from anyone who's worked with FalconStor or similar products and can suggest other things to investigate.

TIA, Paul Baumgartel
