I have a 2850 with a perc 4e/di,,,by default I notice that the "write policy" by default is set to "write back". However Netware's paramater "enable hardware write back" by default is set to OFF. So basically to use Writeback I need to set the netware parameter to ON. Correct?

I assume this will increase performance---but at what cost? More chance of corrupt data?

Also I notice the PERC "cache policy" is set default to "direct io". Should that change?

Maybe someone can explain these for me a bit as well. Thanks!
