There were no new features added in the July 8th HCX Service Update. Fixed issues are mentioned in the release note, we won’t explore those any further in this post.


The HCX R123 update from July 23 includes some preliminary changes for some upcoming features, along with another round of fixes.

One change can be seen notably in the Compute Profile creation interface, where HCX services are selected:

What is HCX Replication Assisted vMotion (RAV)? RAV combines the advantages of Bulk Migration (parallel operations, resiliency and scheduling) with the advantages of HCX vMotion (zero downtime state compatible migration) as one operation.

What is the OS Assisted Migration service (OSAM)? OSAM can be used to bring openstack workloads into a vSphere environment.

What is the SRM Integration Service? HCX integration with SRM provides the ability to configure DR from VMware SRM where HCX is an extension providing optimized deduplication of Virtual Machine leveraging the HCX Interconnect.

These features will be available in the near future. Looking forward to exploring them in detail.
