The SAN/Legacy storage array is connected to the Fibre Channel (FC) switches. A dual port FC channels adapter is installed on the HCI nodes and is connected to the same Fibre Channel switches that the SAN/Legacy storage array is connected to.
The zoning is configured using the SAN management console to ensure that the FC adapters are visible to the storage array for mounting/presenting volumes from the SAN/Legacy storage array.
The VM that is hosted on the PowerFlex HCI system is configured to access the FC adapters on the HCI Nodes as a Direct IO device. The volume that is presented is visible only to the VM and to the HCI Nodes.
