Abstract: Examples described herein may include management of a ROBO site. An example method includes detecting a first configuration of a first computing node cluster of a computing system over a first network, and detecting a second configuration of a second computing node cluster of the computing system over a second network. The example method further includes receiving a request to update a configuration of the computing system. The update includes an update of the first configuration of the first computing node cluster. The example method further includes determining whether the update of the first configuration of the first computing node cluster is compatible with the second configuration of the second computing node cluster, and in response to the update of the first configuration of the first computing node cluster being incompatible with the second configuration of the second computing node cluster, denying the request.

Abstract: An architecture for implementing a distributed metadata system in a virtualization environment comprising a plurality of servers, wherein each server may access and operate upon the entirety of the metadata in the virtualization environment. In response to a request received at a server to operate upon the metadata, existing metadata associated with the request is read by the server. The server performs one or more updates based upon the retrieved metadata, and attempts to update the corresponding stored metadata. In some embodiments, attempting to update the stored metadata comprises reading the metadata again and comparing it to the originally retrieved metadata, and performing the update only if the newly retrieved metadata matches the originally retrieved metadata.
