OMNI vCenter integration
This information describes the OMNI vCenter integration to automate vCenter PortGroup VLANs.
vCenter VSS and DVS PortGroups
When you configure PortGroups of a virtual standard switch (VSS) with VLANs and distributed virtual switch (DVS) with
VLANs on the OMNI registered vCenter, the respective active and standby physical adapter interfaces are automatically
configured by OMNI on the SmartFabric ServerInterfaces. This is shown as tasks on the registered vCenter tasks pane.
NOTE: You cannot delete PortGroups on a VSS/DVS, or delete the VSS/DSS entirely as it clears all unused networks
from the SmartFabric ServerInterfaces.
DVS provides an option to change the VLAN of uplink
PortGroups. OMNI ignores PortGroup configuration if the VLAN type
PortGroup is set to VLAN trunking or private VLAN.
We recommend keeping the DVS uplink in Trunking mode and configure the virtual PortGroups with VLANs for each network.
OMNI configures the respective VLANs on the ToRs and SmartFabric uplinks.
OMNI automates the vCenter PortGroup VLAN and manages the registered vCenter by identifying the relation between the
SmartFabric ServerInterface and the ESXi host PNIC MAC.
Identification of vCenter ESXi Host by OMNI
OMNI collects the PNIC MACs of all ESXi hosts in registered vCenters. If OMNI identifies the ServerInterface ID as a
collected PNIC MAC (Id=MAC without ':') of the host, OMNI identifies that host to belong to an OMNI registered SmartFabric
instance.

Add/update PortGroup: VLAN of VSS/DVS
● Create network of PortGroup VLAN and set Network
Originator to Auto
● Add network to SmartFabric ServerInterface
Remove PortGroup from VSS/DVS Remove unused networks from SmartFabric
ServerInterface
NOTE: OMNI automation is not designed to delete unused ServerInterfaces of SmartFabric.
SmartFabric networks consolidation by OMNI
1. Collect all networks of registered SmartFabric.
2. Collect networks of ServerInterface of registered SmartFabric.
3. Identify SmartFabric networks created by the OMNI user interface, and SmartFabric networks that are not created by the
OMNI user interface.
OMNI distinguish the origin of the network configured through vCenter or OMNI user by setting the Network
Originator parameter.
a. OMNI sets Network Originator to Manual when an user creates a network using OMNI UI.
b. OMNI sets Network Originator to Auto when OMNI vCenter PortGroup automation creates a network.
