Working with the Rolling System Update function

Rolling System Update (RSU) provides a nondisruptive approach to firmware updates. RSU fully manages firmware by orchestrating "rolling" updates, leveraging dynamic virtual machine movement within a defined VMware cluster, completing the whole update process, including ESXi host restart automatically, without any interruption to application services running on the host.

Users can update the firmware by using the Rolling System Update function if the vSphere Lifecycle Manager cannot be used in some scenarios. For example, the cluster is not managed by a single image, or users are intended to upgrade some firmware not in the firmware packages for vLCM.

For more information about updating firmware through vLCM, refer to Working with the vSphere Lifecycle Manager function.
