摘要： Snapshots that are consistent across a group of data objects are generated. The snapshots are initiated by a coordinator, which transmits a sequence of commands to each storage node hosting a data object within a group of data objects. The first command prepares a data object for a snapshot. After a data object has been successfully prepared, an acknowledgment is sent to the coordinator. Once all appropriate acknowledgments are received, the coordinator sends a command to confirm that a snapshot has been created for each data object in the respective group. After receiving this confirmation, the coordinator takes action to confirm or record the successful completion of the group-consistent snapshot.
摘要翻译：生成一组数据对象中一致的快照。快照由协调器启动，协调器将一系列命令发送到承载一组数据对象内的数据对象的每个存储节点。第一个命令准备快照的数据对象。在数据对象成功准备好之后，将向协调器发送确认。一旦接收到所有适当的确认，协调器将发送一个命令，以确认已为相应组中的每个数据对象创建快照。收到此确认后，协调员将采取行动确认或记录成功完成组一致的快照。

摘要： Consistent replicas of a data object are created using a replication protocol that includes an opportunistic replication phase followed by a consistent replication phase. During the opportunistic replication phase, dirty regions are selected from the data object included in a primary computer and copied to a data object replica included in a secondary computer according to a selection heuristic. During the consistent replication phase, an immutable image of the data object is created by the primary computer and the remaining dirty regions are copied from the immutable image of the data object to the data object replica to create a consistent replica of the data object.

摘要： Techniques are disclosed for managing a cluster of computing nodes following a division of the cluster into at least a first and second partition, where the cluster aggregates local storage resources of the nodes to provide an object store, and objects stored in the object store are divided into data components stored across the nodes. In accordance with one method, it is determined that a majority of data components comprising a first object are stored within nodes in the first partition. It is determined that a majority of data components comprising a second object are stored within nodes in the second partition. Configuration objects are permitted to be performed on the first object in the first partition while denying access to the first object from the second partition, and on the second object in the second partition while denying access to the second object from the first partition.

摘要： Embodiments presented herein techniques for balancing a multidimensional set of resources of different types within a distributed resources system. Each host computer providing the resources publishes a status on current resource usage by guest clients. Upon identifying a local imbalance, the host computer determines a source workload to migrate to or from the resources container to minimize the variance in resource usage. Additionally, when placing a new resource workload, the host computer selects a resources container that minimizes the variance to further balance resource usage.

摘要： Embodiments of the disclosure provide techniques for measuring congestion and controlling quality of service to a shared resource. A module that interfaces with the shared resource monitors the usage of the shared resource by accessing clients. Upon detecting that the rate of usage of the shared resource has exceeded a maximum rate supported by the shared resource, the module determines and transmits a congestion metric to clients that are currently attempting to access the shared resource. Clients, in turn determine a delay period based on the congestion metric prior to attempting another access of the shared resource.

摘要： Techniques are described for storing a virtual disk in an object store comprising a plurality of physical storage devices housed in a plurality of host computers. A profile is received for creation of the virtual disk wherein the profile specifies storage properties desired for an intended use of the virtual disk. A virtual disk blueprint is generated based on the profile such that that the virtual disk blueprint describes a storage organization for the virtual disk that addresses redundancy or performance requirements corresponding to the profile. A set of the physical storage devices that can store components of the virtual disk in a manner that satisfies the storage organization is then determined.

摘要： Techniques are disclosed for providing a file system interface for an object store intended to support simultaneous access to objects stored in the object store by multiple clients. In accordance with one method, an abstraction of a root directory to a hierarchical namespace for the object store is exposed to clients. The object store is backed by a plurality of physical storage devices housed in or directly attached to the plurality of host computers and internally tracks its stored objects using a flat namespace that maps unique identifiers to the stored objects. The creation of top-level objects appearing as subdirectories of the root directory is enabled, wherein each top-level object represents a separate abstraction of a storage device having a separate namespace that can be organized in accordance with any designated file system.
