What dictates the # of device streams setting for a storage policy?
Our maglibs mount paths allocation policy are all set to 'maximum allowed writers'
From CV's documentation below, can someone clarify 'sum of drives available and/or the sum of writers...'? Is it the physical # of hard drives that make up the LUN? Is it the total # of mount paths for all libraries (used as alternate data paths)? Also, we just changed the device streams on our storage policies for file system from 5 to 10 to see how it goes (as a lot of the jobs were queued over the weekend as the storage policy could only handle 5 streams). How will the system behave if, let's say, we bumped it up to 20, or even 30, device streams?
From CV's documentation below:
"If alternate data paths are added, it is recommended that the number of streams must be equal to the sum of drives available in all the libraries and/or the sum of writers in all the magnetic library/mount paths associated with all the data paths."
