VMware has released a new web site ports.vmware.com that conveniently contains all used ports per product. Not all products are covered yet but let's hope that's a matter of time. Here is an example of ports for NSX for vSphere with a filter that shows the ports used when ESXi is the source. This allows you to conveniently find the used ports per component.

A customer asked if it is possible to allow AD users to manage an existing virtual machine through an HTML connection. In this short video I am showing this setup with two VMs (each in their own pool) that can be accessed by two individual users that are members of an AD Group. To accomplish this you would have to create a Manual Floating pool with 1 VM per pool that can be accessed by multiple users (not simultaneously). Use a manual pool to make sure VMs are not deleted or otherwise managed by Horizon.

When you study how vSAN works then you will read about how objects are backed by one or more components. This is dependent on the fault tolerance level and what you would also read is that a tie-breaker witness will be created. This is to make sure that when a network partition occurs, servers in a network partition can decide whether or not they together hold more than 50% of the necessary components and/or witnesses.
