Patent number: 9594924Abstract: Various embodiments are provided for managing a global cache coherency in a distributed shared caching for a clustered file system (CFS). The CFS manages access permissions to an entire space of data segments by using the DSM module. In response to receiving a request to access one of the data segments, a calculation operation is performed for obtaining most recent contents of one of the data segments. The calculation operation performs one of providing the most recent contents via communication with a remote DSM module which obtains the one of the data segments from an associated external cache memory, instructing by the DSM module to read from storage the one of the data segments, and determining that any existing contents of the one of the data segments in the local external cache are the most recent contents.Type: GrantFiled: January 19, 2016Date of Patent: March 14, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lior Aronovich, Yair Toaff, Gil Paz, Ron Asher

Patent number: 9536104Abstract: Various embodiments are provided for managing a global cache coherency in a distributed shared caching for a clustered file system (CFS). The CFS manages access permissions to an entire space of data segments by using the DSM module. In response to receiving a request to access one of the data segments, a calculation operation is performed for obtaining most recent contents of one of the data segments. Most recent contents are determined if ownership of the one of the data segments is possessed by a remote DSM module and the request to access one of the data segments is for shared permission and exists in the local external cache. The most recent contents are transported within the response if the response is in a remote external cache and has a valid permission for the one of the data segments otherwise reading from the one of the data segments.Type: GrantFiled: December 3, 2015Date of Patent: January 3, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lior Aronovich, Yair Toaff, Gil Paz, Ron Asher

Patent number: 8788547Abstract: Systems. Methods, and Computer Program Products are provided managing global cache coherency and reducing contention and messaging traffic in a distributed shared caching for a clustered file systems (CFS). The CFS manages access to data segment space of the data segments shared between a cluster of nodes by using the file access component.

Patent number: 8738671Abstract: Systems. Methods, and Computer Program Products are provided managing a global cache coherency and reducing messaging traffic for coordination of access permissions in a distributed shared caching for a clustered file systems (CFS). The CFS manages access permissions to an entire space of the data segments by using the DSM module. In response to processing a request message from a remote DSM module to access one of the data segments, including in a response message permission to access the one of the data segments, and deciding if one of a transfer of ownership, and most recent contents of the one of the data segments should be included in the response message for the permission to access the one of the data segments. The last two components of the response message depend upon availability of the one of the data segments that is requested in a local external cache.Type: GrantFiled: January 3, 2013Date of Patent: May 27, 2014Assignee: International Business Machines CorporationInventors: Lior Aronovich, Yair Toaff, Gil Paz, Ron Asher

Patent number: 8560581Abstract: Systems. Methods, and Computer Program Products are provided for recovering transactions of failed nodes using a recovery procedure in a clustered file system (CFS). A data segment is determined that the data segment should be copied to a final storage location by validating that an ownership of the data segment is not associated with any other operational node, via a distributed shared memory (DSM) agent. The ownership of the data segment is set to a local DSM agent.Type: GrantFiled: August 6, 2012Date of Patent: October 15, 2013Assignee: International Business Machines CorporationInventors: Lior Aronovich, Yair Toaff, Gil Paz, Ron Asher

Patent number: 8516020Abstract: Systems, Methods, and Computer Program Products are provided for performing concurrent checkpoints from file system agents residing on different nodes within in a clustered file system (CFS). Responsibility to checkpoint a modified and a committed data segment to a final storage location is assigned to one of the file system agents. One of the file system agents, which is assigned, is the file system agent whose associated distributed shared memory (DSM) agent is an owner of the data segment.Type: GrantFiled: August 6, 2012Date of Patent: August 20, 2013Assignee: International Business Machines CorporationInventors: Lior Aronovich, Yair Toaff, Gil Paz, Ron Asher
