Patent number: 8418159Abstract: An apparatus for optimizing a transaction comprising an initial sequence of computer operations, the apparatus includes a processing unit which identifies one or more idempotent operations comprised within the initial sequence, and which reorders the initial sequence to form a reordered sequence comprising a first sub-sequence of the computer operations followed by a second sub-sequence of the computer operations, the second sub-sequence comprising only the one or more idempotent operations.Type: GrantFiled: November 29, 2009Date of Patent: April 9, 2013Assignee: SAP AGInventors: Eitan Farchi, Shachar Fienblit, Amiram Hayardeny, Rivka Matosevich, Ifat Nuriel, Sheli Rahav, Dalit Tzafrir

Patent number: 8095755Abstract: Generating a consistent point in time copy of data in a source volume and a target volume is achieved responsively to a first data modification request by writing a first altered version of the data onto a single source volume, asynchronously transferring the first altered version from the first storage site to a target volume located at a remote second storage site, while avoiding copying the first altered version onto other volumes at the first storage site. While asynchronously transferring the first altered version de-queuing a second modification request, and responsively to the second modification request synchronously transferring the first altered version from the first storage site to the target volume. Then a second altered version of the data is written to the single source volume and a copy transferred to the target volume in like manner.Type: GrantFiled: April 27, 2009Date of Patent: January 10, 2012Assignee: International Business Machines CorporationInventors: Gal Ashour, Kenneth Wayne Boyd, Michael Factor, Shachar Fienblit, Olympia Gluck, Amiram Hayardeny, Eli Malul, Ifat Nuriel, Noa Privman-Horesh, Dalit Tzafrir, Sam Clark Werner

Patent number: 8005800Abstract: Techniques are provided for performing a copy operation. A fast reverse restore command indicating a new source and a new target is received, wherein the new source is an original target and the new target is an original source. A synchronous scan is performed on the new target. A new target structure associated with the new target is updated using a new source structure associated with the new source. Techniques are also provided for performing a copy operation in which a fast reverse restore command is received after an instant virtual copy has been performed from a new target to a new source and wherein the fast reverse restore command is performed before a background copy has been performed by the instant virtual copy.Type: GrantFiled: October 29, 2010Date of Patent: August 23, 2011Assignee: International Business Machines CorporationInventors: Gail Andrea Spear, Michael E. Factor, Rivka Mayraz Matsoevich, Shachar Fienblit, Sheli Rahav, Robert Francis Bartfai, Dalit Tzafir, Ifat Nuriel

Patent number: 7904684Abstract: Provided are a system and article of manufacture for copying storage. Copy operations are performed on source storage units to copy to target storage units, wherein the copy operations create a consistent copy of the source storage units in the target storage units. While performing a copy operation to copy from one source storage unit to one target storage unit, a write operation is restricted from being performed on the one source storage unit, until the copy operations have been performed on the source storage units.Type: GrantFiled: November 19, 2008Date of Patent: March 8, 2011Assignee: International Business Machines CorporationInventors: Sam Clark Werner, William Frank Micka, Sivan Tal, Ifat Nuriel, Sheli Rahav, Gail Andrea Spear, Warren K.

Patent number: 7650476Abstract: A method for generating a consistent point in time copy of data, the method includes: selecting at least one selected data block to be copied from a source volume to a target volume in response to a request to generate a consistent point in time copy of multiple data blocks; waiting until the source volume is ready to send the at least one selected data block to a remote volume while queuing at least one data block modify request; de-queuing the at least one queued modify requests while copying the at least one selected data block from the source volume to the target volume; wherein the copying includes utilizing a first copying mechanism to copy a first selected data block if a request to modify the first selected block is de-queued before the first selected data block is copied to the target volume; else, the copying includes using a second copying mechanism that is slower than the first copying mechanism.Type: GrantFiled: October 18, 2006Date of Patent: January 19, 2010Assignee: International Business Machines CorporationInventors: Gal Ashour, Kenneth Wayne Boyd, Michael Factor, Shachar Fienblit, Olympia Gluck, Amiram Hayardeny, Eli Malul, Ifat Nuriel, Noa Privman-Horesh, Dalit Tzafrir, Sam Clark Werner

Patent number: 7000145Abstract: Disclosed is a technique for applying changes back to an original copy of data to reduce an amount of data transferred. A first indicator is maintained for each block of data in a first storage to indicate whether the block of data has been updated in the first storage since the block of data was last transferred to a second storage. A second indicator is maintained for each block of data in the second storage to indicate whether the block of data has been updated in the second storage since the block of data in the second storage was overwritten by a corresponding block of data in the first storage.Type: GrantFiled: June 18, 2003Date of Patent: February 14, 2006Assignee: International Business Machines CorporationInventors: Sam Clark Werner, William Frank Micka, Dalit Tzafrir, Matthew Sanchez, Sivan Tal, Ifat Nuriel, Sheli Rahav, Gail Andrea Spear, Warren K.
