Abstract: A file server manager disclosed herein accesses information regarding a selected share of a source distributed file server for replication, where the selected share stores at least a portion of a namespace of storage items and is hosted by a first file server virtual machine of the source distributed file server. The file server manager accesses a mapping between virtual machines of the source distributed file server and virtual machines of the destination distributed file server and replicates the selected share to a second file server virtual machine of the destination distributed file server based on the mapping. The file server manager directs a request to read a first storage item to the destination distributed file server and directs a request to write to a second storage item to the source distributed file server while the destination distributed file server services the request to read the first storage item.

Abstract: Clustered computing system monitoring, fault prediction and remediation. The disclosed techniques are used for predicting an impending occurrence of a fault. Prediction techniques involve gathering historical data pertaining to storage I/O operations performed in a clustered computing system. Ongoing storage I/O operations that are performed when a first node accesses data in local storage device as well as ongoing storage I/O operations that are performed when the first node accesses data in a remote storage device of a second node are monitored over time. On an ongoing basis, the monitored storage I/O operations are analyzed to identify impending remediable events. Before recurrence of a predicted impending remediable event, conditions that are known to have been present at the time of a historical fault are ameliorated. In some embodiments, avoidance of an impending remediable event is accomplished by moving data stored at a remote storage device to a local storage device.

Abstract: A scalable multi-cluster resource sharing facility. A global witness process runs on a first computing platform that communicates over one or more networks to any number of nodes situated over two or more clusters. The global witness process listens on the network for occurrences of leadership and/or resource requests from nodes of different clusters. The global witness processes a request by retrieving a resource request and a respective last known state value, comparing the last known state value to a global stored state value, then storing a new state value when the respective last known state value is equal to the stored state value. Any number of contemporaneous requests can be processed by the global witness process, however only one request can be granted. The other requestors each receive a rejection of their resource request when their proffered last known state value is not equal to the stored state value.

Abstract: A dynamically-managed microservices platform. The microservices platform is configured to selectively accept admission of microservices and to selectively throttle microservices based on a continually-trained machine learning model. The system is configured to implement multiple microservice lifecycle strategies, where individual ones of the multiple microservice lifecycle strategies use a prediction model having long-term and short term demand predictions. One or another of the multiple microservice lifecycle strategies are invoked at different times under different conditions. Under a first set of conditions, a prediction model is used to select a first strategy to admit or throttle a microservice based upon long-term or short-term demand predictions. Under a second set of conditions, the prediction model is used to select a different strategy to admit or throttle a microservice.

Abstract: A unified namespace technique provides coherent access to unstructured data across different data access protocols having different logical constructs that are stored and managed on a storage system. A control plane infrastructure operates in connection with storage services to provide support for a vast array of storage platforms including file servers of a file system and object storage servers of an object store. Metadata associated with a data access transaction is processed separately and natively by a protocol stack of a particular storage service according to a particular data access protocol. The processed metadata is stored native to the access protocol in a metadata store associated with the particular storage service and is made available to the protocol stacks of the other storage services. Processed metadata is made available to the protocol stacks via an event notification logging service implemented as a message bus.

The VFS may be configured to receive a request for storage system information from a user and generate and send a response to the request, wherein the response is customized according to configuration information of the VFS that is specific to the user. The storage system information requested may include a total size of storage available to the user, and the user may have an associated storage quota limit.

Abstract: A method for indexing virtual machine version snapshots in a virtualization environment commences upon receiving a request (e.g., from an administrator or agent) to initiate a virtual machine version snapshot operation on a subject virtual machine. Processes within or controlled by the subject virtual machine are requested to temporarily suspend transactions and file I/O. When the processes that have been requested to temporarily suspend transactions and file I/O acknowledge quiescence, the method continues by generating a virtual machine version snapshot data structure. An entry in an index is formed from the virtual machine version snapshot data structure. Multiple instances of virtual machine version snapshot data structures can be stored in the index, and the index can be queried to determine the state that a virtual machine had at any of the snapshotted moments in time.

Abstract: One embodiment of the present invention provides a system that can manage access to a service from a cluster of computing nodes. An instance of the system can operate on a respective computing node. During operation, the system instance can identify an Internet Protocol (IP) address, which provides access to the service from the cluster of computing nodes to a client device at a client site. The system instance can select the computing node for hosting the IP address in the cluster of computing nodes based on a set of selection criteria. The selection is performed independently at the computing node. The system instance can then assign the IP address to the computing node. The assignment allows a request for the service to be directed to the computing node. Subsequently, the system instance can facilitate the service from the cluster of computing nodes based on the request.
