vSphere 8 vMotion Improvements

vSphere 8 was announced at VMware Explore 2022 in San Francisco. Part of this new major release are vMotion updates. vMotion is extensively developed to support new workloads and is one of the key enablers for VMware’s multi-cloud approach. Whenever a workload is live-migrated between vSphere and/or VMware Cloud infrastructures, vMotion logic is involved.

vMotion In-App Notifications

With the release of vSphere 7, the vMotion logic was updated to greatly reduce the performance impact on applications during live migrations. Significant work was done to minimize the stun-time, aka the switch-over time, where the last memory pages and checkpoint info are transferred from source to destination. (more…)

vSphere 6: vMotion enhancements

Don’t we all remember when we witnessed our first vMotion and realized which awesome things this made possible in virtualization?! ┬áIn vSphere 6 vMotion even got better!

vMotion version history

First I’d like to give a short overview about what was already achieved in previous versions of vSphere.

vSphere 5.0:

  • Multi-NIC vMotion
    Migration time reduced by making Multi-NIC vMotion possible.
  • Stun During Page Send
    Stunned source machine if needed to progress pre-copy phase of vMotion, so the memory modification rate stays below the precopy transfer rate and the pre-copy will eventually succeed.

vSphere 5.1

  • vMotion without shared storage
    Allows for moving the VM simultaneously to another computing & storage resource at the same time.
