This is the limit on the number of migrations active at one time. You should start at LOW to see what the impact is, then up the rate until it impacts performance.

Hi All;  I am having some trouble finding a best practice for how many migrations can occur simultaneously, I will frame my question by showing what I am planning to do:  I am moving 8 1TB LUNS from a storage pool to 8 1TB LUNS in a Raid Group.  The 8 LUNS are evenly spread (4 each) across the SP's.  Is it possible to run all 8 at once (and set the priority to low) or is there a best practice?  The array will not be busy when I am doing this on Saturday, will be very quiet actually.   Thanks for your replies in advance.
