An HCX Service Mesh is the effective HCX service configuration for a paired source and a destination site. You can add a Service Mesh to a Site Pair with a valid Compute Profile created on both sites.
Adding a Service Mesh initiates the deployment of HCX Interconnect virtual appliances on both sites. A Service Mesh is always created at the source site.
Prerequisites:
Creating a Service Mesh requires:
A connected Site Pair.
A valid compute profile at the HCX Source HCX destination site.
For each switch in the Compute Profile at both the source and the destination sites, the switch must span all hosts in at least one of the compute clusters. If the switch does not span all hosts in the compute cluster, then it is possible that the Network Extension appliance is deployed on a different host in a compute cluster and spans across a different switch. In this case, the Service Mesh deployment can fail.
Procedure:
Log in to the HCX Manager: https://hcx-ip-or-fqdn
From the HCX Console, navigate to Interconnect > Multi-Site Service Mesh > Service Mesh. Created Service Mesh configurations are listed.
Click Create Service Mesh:
Select Sites:
Click each drop-down and select a source and a destination site. Only connected Site Pairs are displayed.
Click Continue.
Select Compute Profiles:
Click the Select Source Compute Profile drop-down and select a Compute Profile.
Click the Select Remote Compute Profile drop-down and select a Compute Profile.
Click Continue.
Select the services to be activated, and click Continue.
The HCX services available for activation are based on your selections in the source and remote site Compute Profiles, and based on the service entitlements for each site. In cases where the source and remote sites have been activated with different entitlements, the Service Mesh can inherit entitlements from either site.
(Optional) Override the default Uplink Network Profile:
By default, the HCX interconnect uses Uplink Network Profiles defined in the Compute Profile for the source and the destination sites. You can override the default.
As an example, an override can be useful in Cloud Director-based deployments where an uplink network that deviates from a common configuration is created for an Organization to consume during the Service Mesh creation.
Click the Select Source Uplink Network Profile drop-down.
Select one or more networks. Click Close.
The HCX Service Mesh can use up to three HCX Uplinks, adding network path failover and improving overall resiliency for HCX services. Multiple HCX Uplinks are not aggregated for increased throughput capacity.
The following specific behaviors apply:
HCX attempts to load balance traffic on the Network Extension (HCX-NE) appliance based on the characteristics of the flow and the performance of the uplinks.
HCX does not load balance migration traffic on the Interconnect (HCX-IX) appliance. Additional uplinks might or might not be used.
Click Continue.
Optionally, repeat these steps for the destination site.
Configure the Network Extension appliances deployed per switch or Transport Zone
In Advanced Configuration - Network Extension Appliance Scale Out, review the default Extension appliances per Network Container.
For each entry, set the number of Network Extension appliances that HCX deploys when it activates the Service Mesh configuration.
Extended network service can be carried by a single (standalone) Network Extension appliance at each site, or an HA group that consists of two Network Extension appliances at each site. For example, to create two standalone Network Extension appliances and one HA group for a container entry, set the scale-out number to 4 (2 + 1 x 2 = 4) in the Service Mesh.
The default setting is 1. This setting restricts the Service Mesh to deploying one Network Extension appliance.

Ready to Complete:
To view a summary of the Service Mesh selections, click the here link.
Name the Service Mesh.
The Service Mesh name has a limit of 50 characters.
To create the service mesh, click Finish.
After the Service Mesh configuration is complete, verify under Service Mesh you can see the service mesh that you have created.
