When preparing for a patch installation, it is critical to verify the hardware compatibility. Before initiating a download or install, check the VMware Compatibility Guide to ensure your server hardware and storage controllers are supported by the specific patch level. Additionally, always perform a backup of the vCenter Server configuration and ensure that your virtual machine backups are current. In a production cluster, verify that Distributed Resource Scheduler (DRS) is active so that VMs can be automatically migrated to other hosts, allowing for zero-downtime maintenance as each host enters maintenance mode to apply the updates. vmware vsphere patch download
The VMware Patch Portal remains the centralized hub for manual downloads. To access it, users must navigate to the Broadcom Support Portal, which now houses all VMware product downloads and patches following the acquisition. Once logged in, you can filter by product, such as ESXi or vCenter Server, and select the specific version and build number required. This is particularly useful for environments with "dark sites" or those without direct internet access, as it allows for the offline acquisition of offline bundles in .zip format.
