System and method for retrieving and using block fingerprints for data deduplication
Ling Zheng,Yinfung Fong +1 more
TL;DR: In this paper, a system and method for calculating and storing block fingerprints for data deduplication is presented, where a fingerprint extraction layer generates a fingerprint of a predefined size, e.g., 64 bits, for each data block stored by a storage system.
Patent
System and method for bandwidth optimization in a network storage environment
Paul Jardetzky,Steven R. Kleiman,Roger Keith Stager,Don Alvin Trimmer,Ling Zheng,Yuval Frandzel +5 more
TL;DR: In this paper, a network cache intercepts data requested by a client from a remote server interconnected with the cache through one or more wide area network (WAN) links (e.g., for Wide Area File Services, or “WAFS”).
Patent

Jason Lango,Brian Mederic Quirion,Ling Zheng,Robert Lieh-Yuan Tsai,Matthew Amdur,Ram Kesavan,David Grunwald,Kartik Ayyar,Robert M. English,J. Christopher Wagner,Paul Eastham,Emmanuel Ackaouy,Ashish Prakash +12 more
TL;DR: In this article, a file-level protocol for coherency checking for use in retrieving data stored on a backing store remote from a storage system is presented. But the file level protocol is limited to sparse volumes.
Patent
System and method for sampling based elimination of duplicate data
TL;DR: In this paper, a technique for eliminating duplicate data is provided, in which one or more anchor points are identified within the data set and a bit-by-bit data comparison is performed of the region surrounding the anchor point in the received data set with the regions surrounding an anchor point stored within a pattern database to identify forward/backward delta values.
Patent
Single-system configuration for backing-up and restoring a clustered storage system
Ling Zheng,Ajith Balachandran +1 more
TL;DR: In this article, the authors propose a method to back-up and restore a clustered storage system using a virtual volume and a physical backup device connected with one of the plurality of storage servers.
