Dice Pool Limit This is the limit of how many dice you can roll for a single action. Dice Pool limit is always set to 20 unless raised by an ability or effect. You may however, split your dice pool or absorb penalties if your dice pool is greater than 20. For instance, if your dice pool for accuracy is 30, you may split it and make 2 attacks at 15 each, or if you have multiple penalties you can absorb such penalties with the 30 dice, but must roll no more than 20 even if you have some remaining. Whenever you spend edge on a roll you may break the dice pool limits. DV and Soak are never affected by dice pool limits, but generally all other rolls are.
DV DV is the number of damage dice that need to be rolled. For instance, DV 15 means you will roll 15 dice and count the hits as damage. DV is not limited by a dice pool limit.
