| 20110289350 | Restoration of an Image Backup Using Information on Other Information Handling Systems - A backup and restoration process which first attempts to recover information blocks from locally connected information handling systems executing a backup/restore service before looking to the slower access cloud store to recover data blocks. | 11-24-2011 |
| 20120030509 | MECHANISM FOR MAINTAINING CACHE SOFT REPAIRS ACROSS POWER STATE TRANSITIONS - A processor core includes one or more cache memories and a repair unit. The repair unit may repair locations in the cache memories identified as having errors during an initialization sequence. The repair unit may further cause information corresponding to the repair locations to be stored within one or more storages. In response to initiation of a power-down state of a given processor core, the given processor core may execute microcode instructions that cause the information from the one or more storages to be saved to a memory unit. During a recovery of the given processor core from the power-down state, the processor core may execute additional microcode instructions that cause the information to be retrieved from the memory unit, and saved to the one or more storages. The repair unit may restore repairs to the locations in the cache memories using the information. | 02-02-2012 |
| 20130166946 | DISASTER RECOVERY PRODUCTION TAKEOVER - Various embodiments for disaster recovery (DR) production takeover in a computing environment by a processor device are provided. If, for a designated storage system operable in the computing environment, a takeover operation may be executed, and a DR storage system has validly replaced the designated storage system using a replacement process, a withdrawal of a DR mode of operation is performed, and ownership of at least one storage device operable in the computing environment is transferred to the DR storage system. The replacement process authorizes the DR storage system to transfer the ownership while withdrawn from the DR mode of operation. | 06-27-2013 |
| 20140344617 | SELECTIVE ACTIVATION OF MEMORY TO RETRIEVE DATA IN A DISPERSED STORAGE NETWORK - A technique of selectively activating inactive distributed storage units of a dispersed storage network to retrieve a threshold number of data slices that are required to recover the original data, instead of utilizing all of the distributed storage units. | 11-20-2014 |
| 20150012776 | USING RDMA FOR FAST SYSTEM RECOVERY IN VIRTUALIZED ENVIRONMENTS - A method, system and computer program product are disclosed for recovery in a virtualized environment using remote direct memory access (RDMA). In one embodiment, the method comprises operating a virtual computer system on a physical computer system, and the virtual system maintains in a memory area a record of a state of the virtual system. In this method, when defined error conditions occur on the virtual system, RDMA is used to pull the record of the state of the virtual system from that memory area onto a standby computer. This record on the standby computer is used to re-initialize the virtual computer. Embodiments of the invention provide methods that provide a very fast recovery from a virtual machine fault or error, while requiring much fewer resources than standard approaches. In embodiments of the invention, one spare real computer system can be used for backing up several virtual systems. | 01-08-2015 |
| 20150121134 | STORAGE DEVICE FAILOVER - Techniques are disclosed relating to storage device failover. In one embodiment, a plurality of storage devices are represented as cluster resources to a cluster resource manager that manages cluster resources on a plurality of cluster nodes. An indication may be received that a failover operation is requested with respect to one of the plurality of storage devices. In response to the indication, the cluster resource manager may initiate the failover operation. In some embodiments, the failover operation includes changing a first access state of the storage device and a second access state of another storage device. In such an embodiment, the storage device and the other storage device may be associated with a logical unit number. In some embodiments, the storage device is located within a first of the plurality of cluster nodes; the other storage device is located within a second of the plurality of cluster nodes. | 04-30-2015 |
| 20150325315 | PRIORITIZED REPAIR OF DATA STORAGE FAILURES - Embodiments are directed towards managing data storage that may experience a data failure. If a repair event is associated with a data storage failure, a new repair task may be generated and added to a task list. A priority value for each repair task in the task list may be determined based in part on the mean-time-to-data-loss (MTTDL) value associated with each repair task in the task list such that a lower MTTDL may indicate a higher priority value over a lower MTTDL. One or more repair tasks may be promoted to become active repair tasks based on the priority value the repair tasks such that the promoted repair tasks have a higher priority that than other repair tasks in the task list, if any. Each active repair task may be executed to repair one or more associated the storage failures. | 11-12-2015 |
