The appliance that manages VCF Operations HCX. One is deployed at each end of a migration from a single OVA image (sized by default at 4 vCPUs, 12 GB of RAM and a 60 GB disk), the pair is linked through site pairing, and a service mesh then rolls out the interconnect, network extension and related service appliances.

Each book explains HCX Manager in context, with comparison tables and the common traps.
Terms in this definition
- 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.
- OVA
Open Virtual Appliance, a VM packaged as a single file; the Azure Migrate appliance for VMware is shipped this way, for example.
- RAM
Memory, whether that of a physical host or of a virtual machine.
- Site pairing
Connecting HCX at a source site to HCX at a destination. Pairs can be one-way, where the source initiates everything, or two-way, sharing a service mesh so either side starts migrations; KVM, Hyper-V and other non-vSphere sites join as pseudo-sites for OS Assisted Migration.
- 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
Fetches a column value from the lookup table, that is the one side of a many-to-one relationship, for whichever row is being evaluated. It therefore needs to run inside an iterator or a calculated column, where row context exists.
Related terms
- HCX Cloud
HCX Manager as installed on the receiving side, needing both vSphere and NSX there. Where two clouds are linked, each end runs HCX Cloud.
- HCX Connector
Legacy vSphere-to-cloud HCX deployments used this label for the source-side HCX Manager, which was matched by HCX Cloud at the other end.
- Proxy Exclusions
In HCX Manager's proxy configuration, a list of local targets (vCenter, ESX, NSX, HCX systems on the internal network) that should be contacted directly rather than through the proxy. Restart the HCX services for edits to apply.
