Configure Oracle Cloud VMware Solution HCX Components

Oracle Cloud VMware Solution deployment is one-click fully automated and ready to use. As part of the automation, the following network settings are configured by default.

VLANs	Network Security Groups (NSGs)	Route Tables
VLAN-S-vSphere VLAN-S-NSX VTEP VLAN-S-vSAN VLAN-S-vMotion VLAN-S-NSX Edge Uplink 1 VLAN-S-NSX Edge Uplink 2 VLAN-S-NSX Edge VTEP VLAN-S-HCX	NSG for VLAN-S-vMotion NSG for VLAN-S-vSphere NSG for VLAN-S-vSAN NSG for VLAN-S-NSX Edge Uplink 1 NSG for VLAN-S-NSX VTEP NSG for VLAN-S-NSX Edge VTEP NSG for VLAN-S-HCX	Route table for VLAN-V-vMotion Route table for VLAN-V-vSphere Route table for VLAN-V-NSX Edge Uplink 2 Route table for VLAN-V-NSX Edge Uplink 1 Route table for Subnet-V Default route table for VMware-SDDC-VCN Route table for VLAN-V-HCX

Subnet-V is the default subnet that’s created as part of the Oracle Cloud VMware Solution network setup. It is used to host the VMware ESXi hosts. A separate security list called Security List for Subnet-V is created for Subnet-V.

You need three separate port groups/VLANs for HCX implementation. However, you can also choose to have the same VLAN-S-vSphere port group for HCX-Management, HCX-vMotion, and HCX-Replication, and as an uplink interface. You can’t use existing ESXi Management or ESXi vMotion networks because the IP addresses are reserved from these VLANs for VMware SDDC cluster expansion.

If you plan to use segregated networking for this implementation, you must create the following VLANs and associated NSGs and route tables. The decision to use an existing VLAN-S-vSphere for all networks or to create separate VLANs for each depends solely on your architectural requirement.

VLANs	NSGs	Route Tables
VLAN-S-HCX-vMotion VLAN-S-HCX-Replication	NSG for VLAN-S-HCX-vMotion NSG for VLAN-S-HCX-Replication	Route table for VLAN-V-HCX-vMotion Route table for VLAN-V-HCX-Replication

Access and Management

Ensure that the required permissions are available to perform VMware HCX operations on premises and in Oracle Cloud VMware Solution. The default vCenter administrator can perform the HCX operations.

Network Connection Between Sites

For information about network connectivity between on-premises VMware environment and Oracle Cloud VMware Solution over FastConnect, see the FastConnect documentation.

DNS Configuration

To ensure that both sites can communicate with each other using FQDN, ensure that both the primary and destination DNS servers have all the forward and reverse lookup entries for both sites’ VMware components that are part of the HCX implementation, such as vCenter, HCX , NSX, and Platform Services Controller (if it’s external). See the Configure DNS for Oracle Cloud VMware Solution section.
