Whats new in vSphere 6.5 Update 1?

Discontinuation of third party vSwitch program

In this release it is possible to use the third party vSwitches like Cisco Nexus 1000V, HPE or IBM DVS 5000v. Customers who are using third party vSwitches have to migrate to the VMware vSphere Distributed Switch in this release. After that release the third party switches will no longer work.

vSphere Client

The biggest improvements in the vSphere client are in management areas of Virtual Distributed Switch, datastore and host configuration. VMware now has completed 90% of general vSphere Client workflows and is pushing hard towards 100%.

Dennis Lu, Product Manager of the vSphere Clients gives some more details in his blog.


One of the new vSAN capabilities is the integration of vSAN to the vSphere Update Manager. This feature will help to find updates including firmware, drivers and vSphere software regarding vSAN. Pete Flecha wrote an interesting blog article about the integration.
