Patent number: 8443000Abstract: In one example, a method may include performance of a hash function on a digital sequence so as to generate a hash value that corresponds to the digital sequence. Next, the digital sequence may be broken into data pieces, and each data piece hashed to produce a corresponding hash value for each data piece. Then, a recipe may be produced that includes instructions which, when executed, may generate the digital sequence from the data pieces referenced by their corresponding hash values included in the recipe. Among other things, the hash values may enable reutilization of redundant data sequences by serving as pointers to the data pieces that the hash values respectively represent.Type: GrantFiled: May 8, 2012Date of Patent: May 14, 2013Assignee: EMC CorporationInventors: Scott C. Auchmoody, Eric W. Olsen

Patent number: 8402063Abstract: In one example, a method of restoring data backed up in a content addressed storage system may include retrieving a recipe and appended storage addresses from a first storage node of content addressed storage, where the recipe may include instructions for generating a data structure from two or more data pieces, and the two or more data pieces may be resident in locations identified by the appended storage addresses. The example method may further include populating a cache with the appended storage addresses for the two or more data pieces. As well the method may further include retrieving, and populating the cache with, the two or more data pieces without looking up a storage address for any of the two or more data pieces in an index, and restoring the data structure using the retrieved two or more data pieces in the cache.Type: GrantFiled: April 30, 2012Date of Patent: March 19, 2013Assignee: EMC CorporationInventors: Scott C.

Patent number: 8386521Abstract: In one example, a system that is operable to back up and restore data may include a high efficiency storage application configured to back up a chunk of data of a client system to a content addressed storage system by generating a recipe that includes instructions for generating the chunk of data from a plurality of data pieces. The system may further include a backup server communicably connected to the high efficiency storage application and configured to, among other things, in response to receipt of a restore request, recover the chunk of data by retrieving the recipe and appended storage addresses in one index seek without separately looking up a storage address for any of the plurality of data pieces in an index.Type: GrantFiled: April 30, 2012Date of Patent: February 26, 2013Assignee: EMC CorporationInventors: Scott C.

Publication number: 20120237386Abstract: A method of making a composite sintered powder metal article includes providing a first powder comprising hard particles and a powdered binder in a first region of a mold. Providing a second powder comprising a metal or metal alloy powder in a second region of the mold, wherein the second powder contacts the first powder and comprises at least one of a metal powder and a metallic alloy powder. The first powder and the second powder are consolidated in the mold to provide a green compact. The green compact is sintered to provide a composite sintered powder metal article comprising a cemented hard particle region formed from the first powder and metallurgically bonded to a metallic second region formed from the second powder.Type: ApplicationFiled: June 4, 2012Publication date: September 20, 2012Applicant: TDY INDUSTRIES, LLCInventors: Prakash K.

Patent number: 8221517Abstract: A macroscopic composite sintered powder metal article including a first region including cemented hard particles, for example, cemented carbide. The article includes a second region including one of a metal and a metallic alloy selected from the group consisting of a steel, nickel, a nickel alloy, titanium, a titanium alloy, molybdenum, a molybdenum alloy, cobalt, a cobalt alloy, tungsten, and a tungsten alloy. The first region is metallurgically bonded to the second region, and the second region has a thickness of greater than 100 microns. A method of making a macroscopic composite sintered powder metal article is also disclosed, herein. The method includes co-press and sintering a first metal powder including hard particles and a powder binder and a second metal powder including the metal or metal alloy.Type: GrantFiled: June 2, 2009Date of Patent: July 17, 2012Assignee: TDY Industries, LLCInventors: Prakash K.

Patent number: 7788220Abstract: Seek operations required to perform backup and/or restore processes at an HFS server are reduced by localizing storage of data referenced by hash values included in a recipe near the recipe. In a typical embodiment, an HFS server receives a recipe and new underlying data for entry into a hash file system. The HFS server identifies a first storage node for the recipe, contiguously stores the new data in the first storage node, and indexes hash values and storage addresses of the new data in storage nodes selected based on the hash values of the new data. Storage addresses for the new data (and other data referenced by the recipe) are appended to the recipe. Later during a restore process, retrieval of the recipe also retrieves the storage addresses. Data pieces stored contiguously can then be collectively retrieved in one seek rather than in separate individual seeks.Type: GrantFiled: December 31, 2007Date of Patent: August 31, 2010Assignee: EMC CorporationInventors: Scott C.
