I have had recent issues with Visual Foxpro 9 apps running on server 2008 and beyond that have a raid 5 configuration. We have found that running RAID 5 configuration causes indexes to become corrupted so our company doesn't recommend RAID 5 configuration. I was asked today by a large firm how many disk I/O arrays would need to be set to allow RAID 50 to be a functional option to run the application. I was stumped by his question. Does anyone know about VFP 9 and RAID configurations using a 40+ user server/client application.
