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.
