Abstract: A system for updating firmware comprises an interface and a firmware update determiner. The interface is for receiving a firmware update bundle, wherein the firmware update bundle comprises a pre-instruction and one or more firmware updates, and for receiving configuration information describing a network cluster. The firmware update determiner is for determining an indication to update a set of nodes of the cluster based at least in part on the configuration information, wherein the indication includes the pre-instruction(s) and the one or more firmware updates. The interface is further for providing the indication to update the set of nodes of the cluster and receiving a summary from each node of the set of nodes of the cluster.

Abstract: A system for a cluster application manager includes an input interface, a command determiner, and a node determiner. The input interface is for receiving a first management request for a management function for a first application of a set of different applications. The command determiner is for determining a first management base command for the first management request. A second management base command is the same as the first management base command for a second management request for the management function for a second application of the set of different applications that is different from the first application of the set of different applications. The command determiner is for determining a management command, wherein the management command is based at least in part on the first management base command and the first application. The node determiner is for determining a node of a cluster to send the management command.

Abstract: Systems, methods, and other embodiments associated with content invalidation are described. One example method includes parsing a response to identify an invalidation directive. Then if identified, invalidating cached content from a cache memory that corresponds to the content identified by an invalidation directive.

Abstract: Asynchronous namespace maintenance in a distributed replicated data storage system is disclosed. An access device/program serving as a front end to the distributed replicated data storage system updates a batch of updated meta data about stored data items when data items are stored in the distributed replicated data storage system. When the elapsed time since the last batch of data item meta data was stored exceeds a first threshold value or the current batch size exceeds a second threshold value, the access device/program stores the current batch of updated meta data as an object in the distributed replicated data storage system, receiving a batch object identifier for the stored batch of updated meta data, and distributes the batch object identifier to other access devices and/or access programs which retrieve the batch of updated meta data and update their namespaces.

Abstract: In a multi-tier data server system, data from the first tier is cached in a mid-tier cache of the middle tier. Access control information from the first tier for the data is also cached within the mid-tier cache. Caching the security information in the middle tier allows the middle tier to make access control decisions regarding requests for data made by clients in the outer tier.
