Hycu is able to fully function in a multi-network environment by having two network adapters assigned to different vlans.
This can be particularly useful when you have a dedicated storage used for backups, which resides on a network different then Hycu. For example:
- Hycu could be located on 10.0.0.0/16 vlan
- Storage machine could be located on 192.168.0.0/24 vlan
Note that even if you configure two vlan's on Hycu VM, Nutanix currently supports only one physical network adapter, so complete physical separation of backup traffic will not be achievable until Nutanix addresses this limitation.
Follow these steps to setup and configure Hycu controller with multiple vlans:
1. Perform clean installation of Hycu as described in Hycu deployment, and finish it's initial setup. After successful deployment, go to Nutanix Prism and edit Hycu VM settings. Add second NIC adapter and select required vlan.
2. Depending how vlan is setup, network configuration can be done in two ways:
a. If vlan has enabled IP address management you can assign the IP address directly from Nutanix Prism.
b. If vlan on which new NIC will be added does not have enabled IP address management, then you can configure network manually by connecting to the Hycu VM using SSH (or launching the console from Prism) and triggering command “sudo nmtui”.
3. Once new network adapter is properly configured your Hycu is ready for adding a target located on another vlan.
Note: If second vlan has enabled IP address management (you configured second vlan using option 2a.) no actions will be needed after upgrade. However, if you manually configured the network on the second vlan (2b.), upgrade process will not preserve the network settings and you will need to reconfigure the vlan after upgrade.
