Riverbed Assigned Two Patents

Virtualized data storage system optimizations
Riverbed Technology, Inc., San Francisco, CA, has been assigned a patent (9,348,842) developed by Wu, David Tze-Si, San Francisco, CA, Nguyen, Huy, Cupertino, CA, Kini, Adityashankar, San Carlos, CA, Uppugandla, Dilip Kumar, and Manjunath, Chinmaya, Sunnyvale, CA, for a “virtualized data storage system optimizations.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Virtual storage arrays consolidate branch data storage at data centers connected via wide area networks. Virtual storage arrays appear to storage clients as local data storage, however, virtual storage arrays actually store data at the data center. Virtual storage arrays overcome bandwidth and latency limitations of the wide area network by predicting and prefetching storage blocks, which are then cached at the branch location. Virtual storage arrays leverage an understanding of the semantics and structure of high-level data structures associated with storage blocks to predict which storage blocks are likely to be requested by a storage client. Virtual storage arrays may use proximity-based, heuristic-based, and access time-based prefetching to predict high-level data structure entities that are likely to be accessed by the storage client. Virtual storage arrays then identify and prefetch storage blocks corresponding with the predicted high-level data structure entities.“

The patent application was filed on March 23, 2010 (12/730,198).

Single-ended deduplication using cloud storage protocol
Riverbed Technology, Inc., San Francisco, CA, has been assigned a patent (9,317,377) developed by Wu, David Tze-Si, Fremont, CA, and Cho, John S., Dublin, CA, for a “single-ended deduplication using cloud storage protocol.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A single-ended optimized storage protocol enables storage clients or other devices to direct a remote data storage to copy data. In response to commands via the protocol, a remote data storage can copy portions of a data stream at the remote data storage to destination storage locations within the same or a different data stream. The protocol may be utilized for optimized transfer of data via a network to a remote data storage. An initial data stream is divided into segments. Redundant segments are removed from the data stream to form an optimized data stream, which is transferred to the remote data storage. Commands are issued to the remote data storage using the protocol to direct the remote data storage to reconstruct the initial data stream at the remote data storage using the optimized data stream and optionally segments from other data streams previously transferred to the remote data storage.“
