How can i find the cause of high disk IOs?
To identfiy the cause of the disk IO peak i want to accomplish the following tasks:

-Where can i find the max. connections of a user, if a connections using a script that opens multiple connection to files on the share?

-Where can i find a process/thread which may cause the high disk IOs?

-Does anyone know any steps to gather this information or have any suggestions what can be the cause of it?
