VMware HCX comprises a virtual management component at both the source and destination sites, and up to five types of VMware HCX Interconnect service appliances depending on the HCX license. VMware HCX services are configured and enabled at the source site, and then deployed as virtual appliances at the source site, with a peer appliance at the destination site.
VMware HCX Enterprise Manager and VMware HCX Cloud Manager
VMware HCX Manager platform is deployed to the management zone, adjacent to each site's vCenter Server, and provides a single plane for administering VMware HCX. The VMware HCX manager provides a sophisticated framework for deploying VMware HCX service VMs across both the local and remote sites. VMware HCX administrators are authenticated, and each task authorized through the existing vSphere SSO identity sources. VMware HCX mobility, extension, protection actions can be initiated from the VMware HCX User Interface or from within the vCenter Server Navigator screen's context menus.
In the HCX site-to-site Architecture, the HCX Managers have a Source or Destination function. HCX Enterprise Manager is always deployed as the source. HCX Cloud Manager is always deployed as the destination. Same types cannot be paired with each other.
In HCX-enabled public clouds, the cloud provider deploys VMware HCX Cloud. The public cloud tenant deploys VMware HCX Enterprise on premises.
In the NSX Hybrid Connect model (HCX for Private to Private deployments), the tenant deploys both source and destination VMware HCX Managers.
HCX-IX Interconnect Appliance
The HCX-IX service appliance provides replication and vMotion-based migration capabilities over the Internet and private lines to the target site whereas providing strong encryption, traffic engineering, and virtual machine mobility.
The VMware HCX WAN Optimization service improves performance characteristics of the private lines or Internet paths by applying WAN optimization techniques like the data de-duplication and line conditioning. It makes performance closer to a LAN environment. It accelerates on-boarding to the cloud using Internet/VPN- without waiting for Direct Connect/MPLS circuits.
HCX Network Extension Virtual Appliance
The VMware HCX Network Extension service provides a late Performance (4–6 Gbps) Layer 2 extension capability. The extension service permits keeping the same IP and MAC addresses during a Virtual Machine migration. Network Extension with Proximity Routing enabled ensures that forwarding between virtual machines connected to extended and routed networks, both on-premises and in the cloud, is symmetrical.
HCX Sentinel Gateway Appliance
Using VMware HCX OS Assisted Migration (OSAM), you can migrate guest (non-vSphere) virtual machines from on-premise data centers to the cloud. The OSAM service comprises the HCX Sentinel software installed on each virtual machine to be migrated, a Sentinel Gateway (SGW) appliance for connecting and forwarding guest workloads in the source environment, and a Sentinel Data Receiver (SDR) in the destination environment.
HCX Sentinel Data Receiver Appliance
The HCX Sentinel Data Receiver (SDR) appliance works along with the HCX Sentinel Gateway appliance to receive, manage, and monitor data replication operations at the destination environment.
