Question about dataServiceEndPoint setting in csi

[gxglls]

Suppose I have three AHV hosts, each host has two network cards, one 1Gbit network card is used as a management network (192.168.10.0/20) , and a 10Git network card used as a storage network (10.0.10.0/24).

My VMs only allocates a network card with the management network 192.168.10.0/20 by default. I hope that dataServiceEndPoint is set on the storage network to avoid IO traffic going to the management network card. Assuming the dataServiceEndPoint is 10.0.0.100, does the vm need to add another network card for the storage network to access the dataServiceEndPoint? If it needs to be added, is there a risk that the broadcast domain will be too large to affect the services of the storage network when the number of VMs is too large?

On the other hand, fileHost only supports the configuration of one ip address, but fileserver does not have VIP. How to ensure high availability?

very thankful！
