System And Method For Creating Deduplicated Copies Of Data Storing Non-Lossy Encodings Of Data Directly In A Content Addressable Store

US Patent:
8299944, Oct 30, 2012
Filed:
Nov 16, 2010
Appl. No.:
12/947438
Inventors:
Christopher A. Provenzano - Somerville MA, US
Assignee:
Actifio, Inc. - Waltham MA
International Classification:
H03M 7/00
US Classification:
341 50, 341 59, 707101
Abstract:
Systems and methods are disclosed for storing deduplicated images in which a portion of the image is stored in encoded form directly in a hash table, the method comprising: organizing unique content of each data object as a plurality of content segments and storing the content segments in a data store; receiving content to be included in the deduplicated image of the data object; determining if the received content may be encoded using a predefined non-lossy encoding technique and in which the encoded value would fit within the field for containing a hash signature; if so, placing the encoding in the field and marking the hash structure to indicate that the field contains encoded content; otherwise, generating a hash signature for the received content and placing the hash signature in the field and placing the received content in a corresponding content segment if it is unique.

System And Method For Improved Garbage Collection Operations In A Deduplicated Store By Tracking Temporal Relationships Among Copies

US Patent:
8396905, Mar 12, 2013
Filed:
Nov 16, 2010
Appl. No.:
12/947383
Inventors:
Christopher A. Provenzano - Somerville MA, US
Assignee:
Actifio, Inc. - Waltham MA
International Classification:
G06F 7/00
US Classification:
707813, 711162, 711216, 711118
Abstract:
Systems and methods are disclosed for performing garbage collection to identify content segments no longer referenced in a deduplicating storage system in which redundant mark operations in a mark-and-sweep technique are avoided. An organized arrangement of hash structures is created for each data object, wherein each structure includes a hash signature for a corresponding content segment and is associated with a reference to the corresponding content segment, and the logical organization of the arrangement represents the logical organization of the content segments as they are represented within the data object. Additionally, for each data object, temporal states are maintained over time. Garbage collection iterates over the temporal structures and, for each temporal structure, marks the garbage collection state for the associated content segments for only the content segments that have changed relative to an immediately prior temporal state of the data object.

System And Method For Creating Deduplicated Copies Of Data By Tracking Temporal Relationships Among Copies And By Ingesting Difference Data

US Patent:
8402004, Mar 19, 2013
Filed:
Nov 16, 2010
Appl. No.:
12/947418
Inventors:
Christopher A. Provenzano - Somerville MA, US
Mark A. Roman - Arlington MA, US
Assignee:
Actifio, Inc. - Waltham MA
International Classification:
G06F 7/00
US Classification:
707692, 711162, 711118, 711216
Abstract:
Systems and methods are disclosed for forming deduplicated images of a data object that changes over time using difference information between temporal states of the data object. The method includes organizing the content of the data object for a first temporal state as a plurality of content segments and storing the content segments in a data store; creating an organized arrangement of hash structures to represent the data object in its first temporal state; receiving difference information for the data object; forming at least one hash signature for the changed content; and storing the changed content that is unique in the data store as content segments, whereby a deduplicated image of the data object for a second temporal state is stored without requiring reception of a complete image of the data object for the second temporal state.

System And Method For Creating Deduplicated Copies Of Data By Sending Difference Data Between Near-Neighbor Temporal States

US Patent:
8417674, Apr 9, 2013
Filed:
Nov 16, 2010
Appl. No.:
12/947513
Inventors:
Christopher A. Provenzano - Somerville MA, US
Assignee:
Actifio, Inc. - Waltham MA
International Classification:
G06F 7/00
US Classification:
707692, 711162, 711216, 711118
Abstract:
Systems and methods are disclosed for using a first deduplicating store to update a second deduplicating store with information representing how data objects change over time, said method comprising: at a first and a second deduplicating store, for each data object, maintaining an organized arrangement of temporal structures to represent a corresponding data object over time, wherein each structure is associated with a temporal state of the data object and wherein the logical arrangement of structures is indicative of the changing temporal states of the data object; finding a temporal state that is common to and in temporal proximity to the current state of the first and second deduplicating stores; and compiling and sending a set of hash signatures for the content that has changed from the common state to the current temporal state of the first deduplicating store.

Systems And Methods For Efficient Memory Allocation For Streaming Of Multimedia Files

US Patent:
2002016, Oct 31, 2002
Filed:
Apr 19, 2002
Appl. No.:
10/126460
Inventors:
Thomas Pinckney - Cambridge MA, US
Garry Kessler - Westboro MA, US
Christopher Provenzano - Somerville MA, US
Benjamin Thomas - Bedford MA, US
International Classification:
G06F015/16
US Classification:
709/231000
Abstract:
Systems and methods for streaming of multimedia files over a network are described. A streaming delivery accelerator (SDA) receives content from a content provider, caches at least part of the content, forming a cache file, and streams the cache file to a user. The described systems and methods are directed to separate (shred) the content into contiguous cache files suitable for streaming. The shredded cache files may have different transmission bit rates and/or different content, such as audio, text, etc. Checksums can migrate from the content file to the shredded cache files and between different network protocols without the need for recomputing the checksums.

Systems And Methods For Efficient Cache Management In Streaming Applications

US Patent:
2002016, Nov 14, 2002
Filed:
Apr 19, 2002
Appl. No.:
10/126986
Inventors:
Thomas Pinckney - Cambridge MA, US
Joshua Cates - Cambridge MA, US
Russell Hunt - Willow Springs NC, US
Christopher Provenzano - Somerville MA, US
Benjamin Thomas - Bedford MA, US
Douglas Wyatt - Somerville MA, US
International Classification:
G06F013/28
G06F013/00
G06F012/16
G06F012/14
G06F012/00
US Classification:
711/118000
Abstract:
Systems and methods for streaming of multimedia files over a network are described. A streaming delivery accelerator (SDA) caches content from a content provider and streams the cached content to a user. Cached content is incrementally added to the cache memory, and the SDA is disconnected from the content provider when sufficient content for a predetermined time of play has been received. The caching process can be iterative, with only content not previously retained in the cache requested from the content provider. A method for cache eviction of content no longer of interest to users is also described.
