- Support for Custom ISO Images: vSphere 7 Lifecycle Manager provides support for custom ISO images, making it easy to upgrade ESXi hosts using your own custom ISO images.
Baselines vs Images:
vSphere 7 Lifecycle Manager uses baselines and images to manage the lifecycle of vSphere components.
Baselines:
A baseline is a collection of patches, extensions, or updates that are grouped together and treated as a single unit in vSphere 7 Lifecycle Manager. Baselines can be either predefined by VMware or custom-created by the administrator. There are two types of baselines:
- Host Baseline: A host baseline is a collection of patches and updates for ESXi hosts.
- Content Baseline: A content baseline is a collection of patches and updates for vCenter Server and other vSphere components such as NSX-T.
Images:
An image is a complete set of binary files that represent a specific version of ESXi. vSphere 7 Lifecycle Manager uses images to upgrade ESXi hosts. Images can be either predefined by VMware or custom-created by the administrator. There are two types of images:
- ISO Images: ISO images are complete binary files that represent a specific version of ESXi. ISO images can be used to perform fresh installations or upgrades of ESXi hosts.
- Offline Bundle Images: Offline bundle images are packages that contain the required binary files to upgrade an ESXi host. Offline bundle images can be used to upgrade ESXi hosts without the need for a network connection.
To upgrade an ESXi host using vSphere 7 Lifecycle Manager, you need to select an appropriate baseline or image for the upgrade. Baselines and images are selected based on the current version of the vSphere component and the desired target version.
In conclusion, Baselines are collections of patches and updates for vSphere components, while Images are complete sets of binary files that represent a specific version of ESXi. vSphere 7 Lifecycle Manager uses baselines and images to manage the lifecycle of vSphere components and to perform upgrades.
Conclusion:
vSphere 7 Lifecycle Manager is a new feature introduced in vSphere 7 that provides a centralized, automated and simplified way to manage and upgrade the lifecycle of vSphere infrastructure components such as vCenter Server, ESXi hosts, and NSX-T. With its key features such as centralized management, automated upgrade, compliance management, rollback capabilities
