The IOMeter documentation says that by monitoring an application's usage of resources in performance monitor, one can then enter them in IOMeter and replicate the system load.
That's fine for settings such as Disk Transfer Bytes, Percentage R/W etc. However, I can't find out how to determine the '# of Outstanding I/Os' to specify in the IOMeter test. This figure apparently makes a big difference to the results seen in IOMeter.
So for example, say I want to replicate a SAS application's load on the system using IOMeter, where/how do I find out the '# of Outstanding I/Os' setting to specify in IOMeter.
Trawling the web I have seen various numbers used in people's tests but nothing that says how they came to that figure.
Any advice appreciated. Thanks
