Create the 802.1q VLAN ID (assume already done), each port for that storage VLAN must be set [U]ntagged for that VLAN only, and the same ID must be used as PVID. That's it.
The reason why you can't ping the other devices with their static IP config is that the incoming ICMP ping might go to the wrong PVID - this is defining where incoming untagged frames are associated to (which VLAN).
