Abstract: Systems for cluster computing. A method for detection and remediation of degraded nodes in a cluster commences upon measuring operational aspects of the nodes in the cluster, then determining, based on the measurements and other factors, a suspect set of nodes comprising one or more suspect nodes from the nodes in the cluster that have measurements that are determined to be outliers with respect to remaining nodes that are determined not to be the outliers. A density-based spatial clustering analysis is performed over the suspect set and remediation actions are initiated when results of the density-based spatial clustering analysis identifies a suspect node as being a degraded node.

Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to map a plurality of objects to a region and map the region to a plurality of vdisks. The plurality of objects are stored in the plurality of vdisks. The processor has programmed instructions to, responsive to mapping the plurality of objects to the region, identify a policy associated with the region. The policy specifies a policy action in response to satisfying a predetermined condition. The processor has programmed instructions to, responsive to satisfying the predetermined condition, access the plurality of vdisks and perform the policy action on the plurality of objects.

Abstract: A system and method for transmitting data from a local management system of a remote office branch office site in a virtual computing system to a central management system includes assigning, by the local management system, an initial priority to each piece of data, identifying data requested by the central management system since a previous data transmission, and updating the initial priority of each piece of data to an updated priority. The data requested by the central management system is prioritized higher than other data. The system and method also include combining, by the local management system, at least a portion of the data starting with data having a highest priority, into a data packet until the data packet achieves a computed data packet size, transmitting the data packet to the central management system, and updating the initial priority with the updated priority for future data transmissions.

Abstract: A method embodiment commences upon identifying an on-premises storage area such as a file or virtual disk that is composed of a set of data blocks. A history of data access patterns over the data blocks is determined by observing accesses to the data blocks over time. When offsite storage is demanded (e.g., such as to a cloud-based storage facility), one or more storage objects are formed such that the blocks in a first one of the one or more storage objects comprise the blocks that have been measured to have the highest access rates (e.g., most recently accessed or most frequently accessed). Metadata that serves as a map is stored with the storage objects. A process or thread can access the storage objects in expectation that the most recently accessed or most frequently accessed blocks will be available in the first ones of the one or more storage objects.

Abstract: Systems and methods for migrating a plurality of virtual machines (VMs) from a private cluster to a public cloud include identifying the plurality of VMs currently residing in the private cluster to be migrated to the public cloud. A communication graph indicative of communications involving the plurality of VMs is determined. A migration sequence for the plurality of VMs based on the communication graph is generated. The plurality of VMs is migrated from the private cluster to the public cloud according to the migration sequence.

Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor and a memory. In some embodiments, the memory includes programmed instructions that, when executed by the processor, cause the apparatus to store a first object and a second object in a first region based on the first object and the second object having a first policy. In some embodiments, the memory includes programmed instructions that, when executed by the processor, cause the apparatus to store a third object in a second region based on the third object having a second policy. In some embodiments, a virtual disk includes the first region and the second region.

Abstract: Systems and methods for scheduling storage management tasks over predicted user tasks in a distributed storage system. A method commences upon receiving a set of historical stimulus records that characterize management tasks that are run in the storage system. A corresponding set of historical response records comprising system metrics associated with execution of the system tasks is also received. A learning model is formed from the stimulus records and the response records and formatted to be used as a predictor. A set of forecasted user tasks is input as new stimulus records to the predictor to determine a set of forecasted system metrics that would result from running the forecasted user tasks. Management tasks are selected so as not to impact the forecasted user tasks. Management tasks can be selected based on non-contentions resource usage between historical management task resource usage and predictions of resource usage by the user tasks.
