vmax 40k fastvp pool rebalancing

Hi,

In pool with ~200 data devices, with ~80% used capacity, I've added ~50 devices with same capacity.

I have

     Rebalance Variance               :   1%

and if I start rebalancing used capacity will try to be in this 1% variance on all disks. I don't know if there is some parameter which can set the speed of rebalancing, I don't want to hammer this pool, and degrade performance.

Or I need to set rebalance veriance to very high value ( 79 % ) and start rebalancing, and when it's done lover rebalance variance again?

Regards
