Configuration of VLAN/Subnets for Storage Spaces Direct (S2D) Cluster
Configuration of VLAN/Subnets for the Troubleshooting Series, Part 1-3
Shows the steps for the Part 1, how to change from 1x VLAN to 2x VLANs.
Configuration of System Center Virtual Machine Manager (SCVMM)





Demo Part #1 - Demo with two vlan/subnets.

The demo shows a Windows Server 2019 cluster that has been configured with two vlan/subnets. The subnet only exist in one physical switch, if the vNIC (SMB vNIC) has to move to the second physical NIC it will not have connectivity. The Failover Cluster will "know" that the network connectivity is down...

SET Switch, created from SCVMM
  • vNIC "MGMT"
  • vNIC "SMB11" - vlan 211 > Team Mapping to pNIC1
  • vNIC "SMB12" - vlan 212 > Team Mapping to pNIC2



Demo Part #2 - Demo with two vlan/subnets but the vlans is present in both ToR Switches


The demo shows a Windows Server 2019 Storage Spaces Direct (S2D) Cluster that has been configured with two VLAN/Subnets. The subnet exist in both physical Switches, if the vNIC (SMB vNIC) has to move to the second physical NIC it will have Ethernet connectivity.


SET Switch, created from SCVMM
  • vNIC "MGMT"
  • vNIC "SMB01" - vlan 201 > Team Mapping to pNIC1
  • vNIC "SMB02" - vlan 202 > Team Mapping to pNIC2



Demo Part #3 - Demo with one vlan/subnets


The demo shows a Windows Server 2019 cluster that has been configured with one vlan/subnet. The subnet exist in all physical switchs, if the vNIC (SMB vNIC) has to move to the second physical NIC it will have connectivity.


SET Switch, created from SCVMM
  • vNIC "MGMT"
  • vNIC "SMB01" - vlan 18 > Team Mapping to pNIC1
  • vNIC "SMB02" - vlan 18 > Team Mapping to pNIC2
