Patent number: 10606715Abstract: For efficient high availability for a multi-node cluster using a processor device in a computing environment, using duplicate, standby host-bus adaptors (HBAs) for alternate nodes with respect to a node with the duplicate, standby HBAs using duplicate credentials of active HBAs of the node for shutting down the node, taking an active HBA of the node offline, and/or activating one of the alternate nodes. A failed node is shut down by an active one of the plurality of alternate nodes using a fence device, and all jobs of the failed node are taken over by the active node using a shared data structure including SCSI device assignments, SCSI reservations, and required host notifications.Type: GrantFiled: November 16, 2017Date of Patent: March 31, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H. Akirav, Oren Bar, Roman Barsky, Itay Maoz

Patent number: 10289563Abstract: For efficient reclamation of pre-allocated direct memory access (DMA) memory in a computing environment, hot-add random access memory (RAM) is emulated for a general purpose use by reclamation of pre-allocated DMA memory reserved at boot time by notifying a non-kernel use device user that the non-kernel use device has a smaller window, stopping and remapping to the smaller window, and notifying a kernel that new memory has been added, wherein the new memory is a region left after the remap. The hot-add RAM is split into at least two continuous parts.Type: GrantFiled: January 17, 2017Date of Patent: May 14, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H. Akirav, Oren Bar, Roman Barsky, Itay Maoz

Patent number: 9720757Abstract: In a computer storage system, crash dump files are secured without power fencing in a cluster of a plurality of nodes connected to a storage system. Upon an occurrence of a panic of a crashing node and prior to receiving a panic message of the crashing node by a surviving node loading, in the cluster, a capturing node to become active, prior to a totem token being declared lost by the surviving node, for capturing the crash dump files of the crashing node.Type: GrantFiled: June 20, 2016Date of Patent: August 1, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay Akirav, Roman Barsky, Rafael Buchbinder, Dan Melamed

Publication number: 20170123998Abstract: For efficient reclamation of pre-allocated direct memory access (DMA) memory in a computing environment, hot-add random access memory (RAM) is emulated for a general purpose use by reclamation of pre-allocated DMA memory reserved at boot time by notifying a non-kernel use device user that the non-kernel use device has a smaller window, stopping and remapping to the smaller window, and notifying a kernel that new memory has been added, wherein the new memory is a region left after the remap. The hot-add RAM is split into at least two continuous parts.Type: ApplicationFiled: January 17, 2017Publication date: May 4, 2017Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay H.
