10 Gb Fiber switchport config/dissimilar members

Thanks for any help :)

We are planning to add a 4100 using 10 Gb fiber to an existing group with a 4000 that uses 1 Gb copper

1. While we don't plan to span a volume across these two members, is this type of group configuration supported?

2. The switchport configs for the ISCSI copper is below. Do we want to do a similiar type of switchport configuration for the fiber? 

interface GigabitEthernet2/3/39
 description SAN iSCSI
 switchport
 switchport access vlan 8
 switchport mode access
 mtu 9216
 flowcontrol receive desired
