Volume and lun sizes

Dear Experts,


I have few queries related to volume and lun size best practices. in 7-mode we have volume limitation to 500 so people may prefer bigger volume with more no of luns.

What is the best practice to follow whether to go with small size luns are big  size luns and the corresponding volume sizes. As there is volume limitation is 7-mode usually will go with bigger volumes with multiple luns is that a good practice to get max performance.
