Patent number: 9495377Abstract: Methods, systems, and computer program products are provided for performing a secure delete operation in a wide area network (WAN) including a cache site and a home site. A method includes identifying a file for deletion at the cache site, determining whether the file has a copy stored at the home site, detecting a location of the copy at the home site prior to a disconnection event of the cache site from the home site, deleting the file from the cache site during the disconnection event, and performing a secure deletion of the copy at the home site immediately after a reconnection event of the cache site to the home site.Type: GrantFiled: September 12, 2012Date of Patent: November 15, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lawrence Carter Blount, Deepak Rambahu Ghuge, Shah Mohammad Rezaul Islam, Sandeep Ramesh Patil, Riyazahamad Moulasab Shiraguppi, Renu Tewari

Patent number: 9152325Abstract: One method includes assigning a pointer from multiple logical blocks to the same original physical block if the multiple logical blocks include the same data. The method further includes receiving a command to write data to the first logical block and determining if the first logical block is a frequently accessed logical block. If the first logical block is a frequently accessed logical block, ownership of the original physical block is assigned to the first logical block. If ownership is established, the method includes copying any data stored in the original physical block to a new physical block, assigning a pointer from a second logical block to the new physical block, and performing the write command on the original physical block. A system includes a processor for performing the above method. One computer program product includes computer code for performing the method described above.Type: GrantFiled: July 26, 2012Date of Patent: October 6, 2015Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Rezaul Shah Mohammad Islam, Sandeep Ramesh Patil, Riyazahamad Moulasab Shiraguppi, Gandhi Sivakumar

Patent number: 9009434Abstract: Systems and computer program products are provided for optimizing selection of files for eviction from a first storage pool to free up a predetermined amount of space in the first storage pool. A method includes analyzing an effective space occupied by each file of a plurality of files in the first storage pool, identifying, from the plurality of files, one or more data blocks making up a file to free up the predetermined amount of space based on the analysis of the effective space of each file of the plurality of files, selecting one or more of the plurality of files as one or more candidate files for eviction, based on the identified one or more data blocks, and evicting the one or more candidate files for eviction from the first storage pool to a second storage pool.Type: GrantFiled: August 13, 2012Date of Patent: April 14, 2015Assignee: International Business Machines CorporationInventors: Duane Mark Baldwin, Sandeep Ramesh Patil, Riyazahamad Moulasab Shiraguppi, Prashant Sodhiya

Patent number: 8805797Abstract: Methods, systems, and physical computer-readable storage medium are provided to optimize WAN traffic on cloud networking sites. In an embodiment, by way of example only, a method includes fetching deduplication information from a home site to build a repository comprising duplicate peer file sets, one or more of the duplicate peer file sets including one or more peer files, referring to the repository to determine whether a target file corresponds with a cache copy of a peer file of the one or more peer files included in the duplicate peer file sets, and creating a local copy of the peer file of the one or more peer files, if a determination is made that the target file corresponds with the cache copy of the peer file of the one or more peer files included in the duplicate peer file sets.Type: GrantFiled: February 22, 2012Date of Patent: August 12, 2014Assignee: International Business Machines CorporationInventors: Kalyan Chakravarthy Gunda, Shah Mohammad Rezaul Islam, Sandeep Ramesh Patil, Riyazahamad Moulasab Shiraguppi
