Hi vAdmins,
Following my last post about the latest release of What’s New in VMware HCX 4.8, it’s now time for an exhilarating update. VMware HCX 4.10.0, a minor update, brings forth fresh features, improved interoperability, better usability, enhanced security, as well as updates on known and resolved issues.
Interoperability Enhancements
Easy interoperability from legacy to latest (VCF 5.2 stack), including vSAN MAX.
For a full list of all the supported products, see the VMware interoperatability Matrix:
HCX Assisted vMotion
HCX provides a simple user interface for extending a Layer 2 network. Once you have extended the network, you can proceed to live-migrate one VM at a time. You also have the option to select upgrading the VM tools or VM hardware during HCX vMotion.
Introducing a fresh migration approach known as HCX Assisted vMotion, or HAV. It merges the well-established vCenter vMotion that users are accustomed to, with the monitoring and orchestrated features of HCX. With HAV, customers can streamline the migration process by automating the simultaneous vMotion of multiple VMs directly from HCX.
This swift migration operates at a remarkable line rate of 25/40/100GbE in vSphere 7.0U2 and beyond. HAV migration supports Host to Host transfers as well as Datastore Migration, including the migration of workloads with vGPU and encrypted Virtual Machines.
By using this innovative migration approach, you can seamlessly coordinate migrations between the VMware ESXi hosts linked to the source and target vCenters while leveraging native cross-vCenter vMotion migration capabilities.
Traffic Engineering Enhancements
In its default configuration, HCX ensures encryption of migration and network extension traffic. However, a recent update introduces a Service Mesh feature that allows users to enable or disable encryption for each service independently. Disabling encryption can enhance the performance of data transfers during migration and network extension operations. This option proves beneficial in secure environments where the integrity of Uplink networks is guaranteed.
When should you enable or disable Encrypted transport mode?
Encrypted transports prioritize security in HCX over public networks (default mode)
Unencrypted transports are optimized for much higher NE per-flow performance in fully private datacenter networks
Generic Receive Offload (GRO)
By activating the Generic Receive Offload (GRO) feature in the Traffic Engineering configurations of a Service Mesh, you can enhance the handling of inbound Network Extension traffic. This functionality allows HCX to consolidate incoming TCP packets into larger units, leading to a boost in application performance upon delivery to the workload applications.
And more!
And there are many more improvements.
