About update levels and build numbers (VMware)

You are working on a project, e.g. installing the latest VMware Horizon View on a vSphere 5.5 Platform. The VMware Product Interoperability Matrixes can help you determine which versions of ESXi are compatible with View.

This is not the best example, as this version of View runs on almost all version of ESXi, you might see the issue, as ESXi presents no update levels, just build numbers. So how do you match Update levels to Build numbers?

Implementing CA signed SSL certificates with vSphere 5.x – Part 5– ESXi and Automation

25/05/2015

In the previous posts, we discussed the need for certificates, how to obtain certificates, implementing certificates on a vCenter Server Appliance, vCenter Update Manager server and finally a vCenter Orchestrator Appliance. Although there are more vSphere components, we conclude with the implementation of certificates for ESXi hosts.

ESXi hosts

The configuration of CA certificates is explained in KB “Configuring CA signed certificates for ESXi 5.x hosts (2015499)”. Most important remark in this KB; “Each server must be unique to the component as it ties to the fully qualified domain name of the server. As such you cannot just take a single certificate and apply it to all hosts. Wildcard certificates are currently not supported, but even if they were, it is much more secure to have a proper certificate for each host.”

To create a certificate request for multiple ESXi servers, you can follow the procedure as describes in KB “Configuring OpenSSL for installation and configuration of CA signed certificates in the vSphere environment (2015387)”.
