Receives VMs and networks extended from its VCF Operations HCX partner. Because pairing works in one direction, any operation (service mesh, network extension, migration, or even moving VMs back) is initiated at the source end.

Terms in this definition
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- VCF Operations HCX
Add-on licensed for moving workloads inside and between VCF private clouds and linking those environments, offering bulk or live migration plus network extension so IP addresses can stay the same.
- Pairing
Deployment pipelines link an item in one stage to its counterpart in the next. Deploying overwrites a linked item, but an unlinked item that just shares its name gets copied across as a duplicate.
- Service mesh
In HCX, the object that links a source compute profile to a destination one (together with their network profiles) and deploys paired service appliances, such as Interconnect and Network Extension, at both sites. Moving where appliances sit requires a resync, and adding further meshes scales out migration capacity.
- Network Extension
Migrated VMs keep their IP and MAC addresses because this VCF Operations HCX service bridges their networks (VLAN-tagged distributed port groups, NSX segments or NSX VPC subnets) to the remote site through a pair of appliances. Unless Mobility Optimized Networking is used, the default gateway stays at the source.
Related terms
- Mobility Optimized Networking
Avoids tromboning on networks extended by HCX: migrated VMs route via the destination site instead of back through the gateway at the source. This Network Extension option applies automatically to VMs moved by Bulk migration, whereas vMotion and RAV leave VMs on the source gateway until someone reconfigures them.
- Source site
HCX term for the end of a site pair holding, in its vCenter, the VMs to be moved. Migrations (reverse ones too, in a unidirectional pair), service mesh and network extension are all initiated from there; its counterpart is the destination site.
