Prerequisites for Integrating V Series Nodes with NSX-T

The following are the prerequisites for integrating V Series nodes with NSX-T:

  • VMware vCenter Standard Version must be 7.0 with the required privileges. Refer to Required VMware Virtual Center Privileges for more information on vCenter privileges.
  • Before deploying V Series nodes through GigaVUE-FM, Service segment must be created in the NSX-T manager.
  • NSX-T version must be 3.2.0 or 4.0.0.
  • ESXi hosts must have the minimum vCPU and memory resources.
  • GigaVUE-FM version must be 5.10.01 or later.
  • V Series 2 device OVA image file.
  • Port number 8889 must be available for GigaVUE-FM to access V Series nodes.

Note:   Service insertion is not supported when the VMware NSX-T manager in federation mode.

Note:  You cannot have both GigaVUE-VM and GigaVUE V Series Node visibility solutions deployed on the same vCenter.

The V Series 2 Node OVA image files can be downloaded from Gigamon Customer Portal.

Recommended Form Factor (Instance Types)

The form factor (instance type) size of the GigaVUE V Series Node is configured on the OVF file and packaged as part of the OVA image file. The following table lists the available form factors and sizes based on memory and the number of vCPUs for a single V series node. Instances sizes can be different for GigaVUE V Series Nodes in different ESXi hosts and the default size is Small.
