VMware VSphere Update Manager 5.0

VMware vsphere Update Manager eliminates the hassle of manually tracking and patching VMware vsphere hosts and virtual machines in addition to automatically managing patches. VMware vsphere Update Manager scans the status of VMware vsphere and compares it with the benchmarks set by the administrator, then applies updates and patches to enforce compliance with the prescribed patch standards. The Patch compliance dashboard allows administrators to understand the patch state of the entire virtual infrastructure environment. This feature greatly simplifies the patch management process while protecting the data center from program errors and security breaches.

VMware vSphere Update Manager reduces the risk associated with virtual machine patching by providing the option to take a snapshot of the virtual machine before patching the application and to allow snapshots to be stored within a user-defined time period, If the application of the patch has an unknown negative impact on the virtual machine workload, the virtual machine can be rolled back to a known state, reducing the risk associated with a virtual machine patching failure.

VMware vSphere Update Manager can securely patch offline virtual machines without exposing them to the network, reducing the risk of security issues for non-compliant virtual machines in production environments. Applying patches to offline virtual machines can only be done in a virtual environment, and this action enforces a higher level of patch standards than the physical environment.

VMware vSphere Update Manager also has the ability to apply patches to remote site segments, reducing network usage and allowing patches to be applied to schedules that are appropriate for remote sites.

Let's look at what isVSphere Update Manager. Update Managerto beVMware VSphereenables centralized auto-patching and versioning, and providesVMware Esx/esxisupport for hosts, virtual machines, and virtual appliances, including upgrades and patchingEsx/esxihost, install and update third-party software on the host, upgrade virtual machine hardware,VMware Toolsand virtual devices. Update Managermust be able to pass through the network andVMware VCenterServerconnected. Update Managereach installation must be associated with aVcenterserverThe instance is associated (registered). Update ManagerThe module includes aVSphere ClientThe plug-in and a server component that you run on, this component canVCenter ServerThe system is installed on the same computer, or it can be installed on a different computer. IfVCenter Serversystem isVCenterlink mode is part of a group that is already connected, and you want to use eachVCenter ServerSystem ofUpdate Manager, you must pair eachVCenter Serversystem is installed and registeredUpdate Managerinstance. Only for registeredUpdate Managerinstance ofVCenter ServerThe system uses this instance. To installUpdate Manager, you must have an installedUpdate Manager. In this case, you can use theVMware vSphere Update Manager Download Service(UMDS) to download the update metadata and update the binaries.

The first step in the Update Manager process is to download a set of information about patches, extensions, and virtual device upgrades (metadata). One or more of these patches or extensions will form a baseline for aggregation. You can add multiple datums to a datum group. A datum group is a compound object that consists of a set of non-conflicting datums. You can use datum groups to combine different types of datums and then scan and repair inventory objects as a whole. If the baseline group contains both an upgrade and a hotfix or an extension baseline, the upgrade baseline is performed first. A collection of virtual machines, virtual appliances, and esxi/esx hosts or individual inventory objects can be scanned to check for compliance with benchmarks or benchmarks and fix them later. You can start these processes either manually or through scheduled tasks.

The Update Manager server can be configured to download patches, extensions, and virtual device upgrades from the Internet or from a shared repository. You can also manually import hotfixes and extensions from a ZIP file. Configuring the Update Manager download source is an optional step. If your deployment system is connected to the Internet , you can download upgrades, patches, and extensions to the update Manager repository using the default settings and links . You can also add a URL address to download a virtual device upgrade or a third-party hotfix and extension. Third-party patches and extensions are only available for hosts running on the ESXi5.0 version.

Requirements for systems and databases

install Update manager before the server, you must create a DB instance because update Manager server and update Manager Download serveice support Oracle, Microsoft SQL Server and Microsoft SQL Server2008 R2 Express (64 updatemanager the server must be installed in the 64 bit system on the computer, But Update manager is still 32 bit applications and needs 32

used by The Update Manager database is the same as the VCenter Server database. You can also use a different database, or use an existing database cluster. For best results in a large environment, you should use a dedicated Update Manager database that is located on a different computer than the VCenter Server system database. the Update Manager Server requires administrator credentials to connect to the database. If you change the database user name and password after you install the Update Manager server or UMDS, you can reconfigure Update Manager and UMDS. Without having to reinstall them.
