I recently fixed a problem for a customer whereby their DPM2010 server was very slow to do anything. Even opening up the GUI was taking a long time.
The server in question was a HP Proliant DL380G5.
So to fix it I needed to do 2 things.
- Update the storage controller's firmware and driver.
- As per the image above , login to the msdpm2010 instance and change the value in the red circle to 300 and reboot server.
Problem solved :)
