    Abstract: Examples described herein include systems and methods for backing up and recovering a software-defined data center (“SDDC”). In one example, entities of the SDDC, such as virtual machines, hosts, and clusters, can coexist with corresponding entity stores. The entity stores can store current state information for each SDDC entity. For example, an identifier or name of a virtual machine can be stored in that virtual machine's corresponding entity store. When recovery of a controller is needed, the controller can rebuild state information that has changed after the controller was backed up, by retrieving state information from entity stores of the various SDDC entities.

    Abstract: A method of upgrading virtual machine (VM) management software from a first version to a second version, wherein the first version of the VM management software executes in a plurality of workloads of a plurality of host computers, the plurality of workloads including a first active workload executing on a first host computer, a first passive workload executing on a second host computer, and a first witness workload executing on a third host computer, and the method comprising: creating and powering on a second active workload that is configured to execute the second version of the VM management software; copying state information from the first active workload to the second active workload and continuing execution of the VM management software in the second active workload; and creating and powering on a second passive workload and creating and powering on a second witness workload.

    Abstract: A method for reconciling host membership information in a data center. The method generally includes querying, by a remote management device configured to manage one or more host clusters in the data center, one or more cluster stores to retrieve first host membership information for each of the one or more host clusters, each cluster store being associated with a host cluster of the one or more host clusters, comparing second host membership information stored at the remote management device for the one or more host clusters to the first host membership information to identify one or more discrepancies between the second host membership information and the first host membership information, and updating the second host membership information such that the second host membership information is consistent with the first host membership information.

    Abstract: A method for maintaining fault tolerance in a storage cluster is provided. Embodiments include receiving, by a management component associated with a distributed data store on a cluster of host machines, a request to place a first host machine of the cluster of host machines in a maintenance mode, wherein the first host machine stores given data of the distributed data store. Embodiments include determining whether a second host machine that does not currently store any data of the distributed data store exists in the cluster of host machines. Embodiments include determining, based on whether the second host machine exists in the cluster of host machines, whether to transfer the given data of the distributed data store from the first host machine to the second host machine. Embodiments include initiating the maintenance mode on the first host machine.
