VUM is a vCenter extension that allows for centralized, automated patch and version management
VMware vSphere Update Manager (VUM) is a vCenter extension that allows for centralized, automated patch and version management for VMware vSphere. It is a utility created by VMware to help with vSphere upgrades and can update various VMware components. VUM is part of the VMware vCenter Server Appliance (VCSA) and is automatically enabled when the VCSA is deployed. It is important to note that VUM cannot upgrade the VCSA, but that process is also straightforward and outlined in VMware's guides.
VUM follows a client-server model, and its server-side components can be installed on the same computer running vCenter Server or on a dedicated computer. It integrates with the vSphere C# client, and the VMware vSphere Update Manager Extension can be downloaded and installed using Plug-in Manager. VUM is also enabled automatically when using the vSphere Web Client, requiring no user intervention.
VUM provides centralized patch and version management for ESXi hosts, virtual applications (vApps), and virtual machines (VMs). It simplifies the upgrade and patch process for ESXi hosts, allowing users to schedule updates as needed. VUM also includes an optional component called the Update Manager Download Service (UMDS), which acts as a proxy server for downloading and recalling updates on behalf of a VUM server. This can be useful for organizations with specific security policies that require decoupling the update download process from distribution.
In terms of hardware and software requirements, VUM on a different computer from the vCenter Server requires a 2GHz processor with two logical cores and 2GB of RAM. When installed on the same computer, VUM needs 8GB of RAM. Additionally, VUM needs enough database disk space and a SQL database, which can be either Oracle or Microsoft. VMware provides the VMware Interoperability Matrix to help match compatible versions.

VUM provides an optional component called the Update Manager Download Service (UMDS)
The VMware vSphere Update Manager (VUM) is a vCenter extension that allows for centralized, automated patch and version management for VMware vSphere. VUM provides an optional component called the Update Manager Download Service (UMDS). UMDS is a proxy server that downloads and recalls updates on behalf of a VUM server. It is important to note that UMDS is not responsible for installing the updates, which is still handled by VUM. UMDS is useful in scenarios where the security policies of an organization restrict internet access for the Update Manager VMs. In such cases, UMDS can be configured on a server with internet access, and the export process can be automated to transfer files from UMDS to the Update Manager server.
UMDS has been available for installation on Windows and Linux-based operating systems since its release in version 6.7. The installation procedure is straightforward, and the documentation provides detailed instructions. UMDS requires an internet connection to download patches, and it supports patch recalls and notifications. When a released patch has problems or potential issues, it is recalled, and Update Manager deletes the recalled patches and displays notifications on the Update Manager Notifications tab.
UMDS can be used as a download server, and multiple vCenter Servers can be directed to a centralized repository. This is particularly useful in large environments to consolidate the Update Manager repository. UMDS also provides the flexibility to disable patch downloads for specific versions if they are not required in the environment.
In summary, UMDS enhances the capabilities of VUM by providing a mechanism to download updates and patches for virtual appliances, patch metadata, and binaries. By separating the download process from the distribution, UMDS adheres to organizational security policies and ensures efficient patch management for vSphere environments.

VUM is enabled automatically when using the vSphere Web Client
VMware vSphere Update Manager (VUM) is a utility created by VMware to help with vSphere upgrades. It is a vCenter extension that allows for centralized, automated patch and version management for VMware vSphere. VUM provides an optional component called the Update Manager Download Service (UMDS), which acts as a proxy server to download and recall updates for a VUM server.
VUM follows a client-server model, and its client component is a plug-in that runs on the vSphere Web Client. As such, VUM is automatically enabled when using the vSphere Web Client, with no user intervention required to activate it. The Update Manager icon should be visible on the home screen.
To install VUM, you must first install the Update Manager server component on a Windows machine. After installing the Update Manager server, the Update Manager client interface becomes automatically enabled in the vSphere Web Client.
VUM is integrated into the vCenter Server Appliance (VCSA), and since vSphere 7, the VUM product has evolved and is now called Lifecycle Manager.

VUM is a utility created by VMware to help with vSphere upgrades
VMware vSphere Update Manager (VUM) is a utility created by VMware to help with vSphere upgrades. It is a vCenter extension that allows for centralized, automated patch and version management for VMware vSphere. It provides support for VM and hosts running the VMware ESXi OS. VUM is included in every commercial version of vSphere, and it is the easiest way to keep vSphere current, especially if there are multiple hosts.
VUM follows a client-server model, and the server-side components are installed on the same computer running vCenter Server or on a dedicated computer, depending on the size of the vSphere environment. VUM integrates with the vSphere C# client, and the VMware vSphere Update Manager Extension is available after the VUM server is installed. VUM is automatically enabled when using the vSphere Web Client.
VUM provides visibility into the patch and upgrade status of hosts and virtual machines for compliance to static or dynamic baselines. It also offers preflight cluster-level checklists that report on remediation readiness before deploying patches. VUM can deploy patches downloaded directly from a vendor website, including drivers, CIM, and other updates from hardware vendors for VMware vSphere hosts. It can also update Virtual Machine Hardware Compatibility, similar to physically upgrading a hardware device. VMware recommends against performing this update unless required, as it necessitates a reboot of the guest OS.
VUM provides an optional component called the Update Manager Download Service (UMDS), which acts as a proxy server to download and recall updates on behalf of a VUM server. UMDS can be placed in a DMZ (an Internet-facing perimeter network) with the VUM server on an internal network, and network traffic between them is regulated by firewall rules and policies.

VUM can be used to update Virtual Machine Hardware Compatibility
VMware vSphere Update Manager (VUM) is a vCenter extension that allows for centralized, automated patch and version management for VMware vSphere. It is a utility created by VMware to help with vSphere upgrades and can be used to update Virtual Machine Hardware Compatibility.
VUM provides an optional component called the Update Manager Download Service (UMDS), which acts as a proxy server for downloading and recalling updates on behalf of a VUM server. It can be used to update Virtual Machine Hardware Compatibility by following specific steps. Firstly, it is important to check the VMware Compatibility Guide and VMware Product Interoperability Matrix to ensure that all components of the VMware vSphere environment will remain compatible and supported.
Upgrading Virtual Machine Hardware Compatibility is similar to physically upgrading a hardware device. VMware advises against performing this upgrade unless it is required, as it necessitates a reboot of the guest OS. However, VUM allows users to schedule the update for the next time the virtual machine restarts. After ensuring compatibility, users can create a baseline for the "VM Hardware upgrade to match the host" to initiate the upgrade process.
To update VM hardware compatibility using VUM, users can follow these steps:
- Select "Cluster" or "Host" from the VUM interface.
- Navigate to "Related Objects" or "Virtual Machines" and select the desired VMs.
- Right-click on the selected VMs and choose "Upgrade VM Compatibility" or "Guest OS > Upgrade VMware Tools."
- If using a VUM pre-defined baseline, select "VMware Tools upgrade to match host."
- Review the selected baseline and verify the ESXi image.
- Specify a baseline name and review the details before clicking "Finish."
- Click "Hosts and Clusters," select the cluster, and then click "Attach."
- Attach the desired baseline to the cluster.
- Click "Check Compliance" to verify if the hosts require remediation.
- Once the compliance check is complete, click "Remediate" to apply patches to all nodes in the cluster.
It is important to note that updating VM hardware compatibility is not mandatory. VMware recommends upgrading only if specific features of the new virtual hardware version are required. Additionally, it is advisable to take a snapshot of the VM before the upgrade, allowing for a rollback option if needed.
