What’s New in HCX 4.3.2 (Maintenance Release)

VMware HCX 4.3.2 has published! In our maintenance releases, we emphasize bug fixes and security patches and any changes that improve serviceability or overall stability. This release is no exception. Read the release note here: VMware HCX 4.3.2 Release Note.

Extras Released along with HCX 4.3.2:

Product Maximums

There are two key changes in the HCX 4.3.2 configmax update:

  1. Maximum concurrent HCX Bulk migrations: 250

    This new 250 limit is the HCX Manager limit, across all deployed service meshes.

    The previous limit of 200 is still applicable to a single service mesh.
  2. Maximum Parallel Replications (RAV/Bulk) & Maximum Delta Transfer

    These new entries provide tiered guidance for what is achievable and supported on a single HCX Service Mesh according to measured network underlay characteristics.

    Limits are provided in the following Network Underlay increments
    all increments assume < 100 ms latency & < 0.1 % packet loss
100 Mbps: 10 parallel | CHURN 60GB per RPO cycle
200 Mbps: 20 parallel | CHURN 120GB per RPO cycle
500 Mbps: 50 parallel | CHURN 300 GB per RPO cycle 
 1 Gbps: 100 parallel | CHURN 600 GB per RPO cycle 
 2 Gbps: 200 parallel | CHURN 1200 GB per RPO cycle

This information is explored in greater detail in the Network Underlay Characterization and HCX Performance Outcomes paper, it’s published in VMware Communities.

VMware Ports & Protocols

Entries added for the Network Extension High Availability HA Group connections in ports.vmware.com.

NE HA diagram was also added. You can view it download it in full resolution in the Network Diagrams portion of the Ports & Protocols portal.

Additional Information for Resolved Security Issues & Feature Bugs

Security related fixes are not provided in detail in the release note, but I can say there are a substantial amount of security fixes in this maintenance release. If running the latest security patches is a critical objective, for that reason I would recommend upgrading to this maintenance release.

There are also a handful of fixes not reflected in the published release note. I very strongly recommend 4.3.2 for any deployments using the Mobility Optimized Networking, OS Assisted Migration and HCX Bulk Migrations.
