Abstract: A DRM system is provided wherein when a protected content unit is provided to an access device, the access information associated with the protected content unit is retrieved from the DRM server and provided to the access device in the same transaction in which the protected content unit is provided. Therefore, when the user seeks to access the protected content unit, the access request can be handled locally without the need to rely upon potentially constrained connectivity to the DRM server. The techniques described herein enable an access device to access content protected by a DRM system. When a protected content unit and access information is received at the access device, in one transaction, the protected content unit can be decrypted on the access device using the access information, and/or the access information can be used to enforce a DRM policy associated with the protected content unit.

Abstract: Inter-zone network traffic generated during deletion of a data chunk that has been replicated by employing geographically distributed (GEO) erasure coding is reduced. In one aspect, if a data chunk is to be deleted, partial coding chunks are generated by a source zone and provided to destination zones that store complete coding chunks for updating the complete coding chunks based on combining them with the received partial coding chunks. In another aspect, if a first data chunk is to be deleted and a second data chunk is to be replicated, partial coding chunks are generated by the source zone for each data chunk. Further, the partial coding chunks created for different data chunks can be combined to generate transforming chunks, which can then be transferred to the destination zones. The destination zones can then update the complete coding chunks based on combining them with the received transforming chunks.

Abstract: Parallel storage systems are provided with a burst buffer appliance for storage of a partitioned key-value store across a plurality of storage tiers. The burst buffer appliance is configured to store key-value data on first and second storage tiers comprising respective disjoint subsets of storage. One or more servers in the partitioned key-value store provide (i) an interface between one or more local key-value stores and one or more additional storage architectures, and/or (ii) a key value interface that provides access to at least one hardware key-value store. The local key-values are optionally sorted both locally by the local store and globally by the overall MDHIM framework. The local and global sorting can be leveraged to provide batch input/output (IO) operations that aggregate multiple requests into batch operations on one or more sorted ranges.
