Have you considered trying StorageXpert from Quest?

All,

We are tuning a new vital process on our data warehouse, and it is IO intensive - lots of parallel direct reads and writes. During our testing we are driving IO wait to ~60% (per top).

questions:

is top a valid measure of IO wait?
Is a high io wait an issue to be concerned about?
how else can it be accurately measured?
How can I link IO wait to what is happening inside the database?

Thanks,

Jack
