Does anyone have any experience with striping data on Informix raw devices. We are running HPUX 10.20 on K420's. Informix reads and writes in 2K pages. I have tried the stripesize of 4, which is the minimum HP allows, and performance has not been any better than non-striped data. I have the data striped across four disks. Anyone else using a diff stripesize? I am not sure if I need to take into account the Informix Read-Ahead configuration. Any suggestions welcome. Please send responses to email.
