摘要： Deduplication of data on disk devices based on a threshold number (THN) of sequential blocks is described herein, the threshold number being two or greater. Deduplication may be performed when a series of THN or more received blocks (THN series) match a sequence of THN or more stored blocks (THN sequence), whereby a sequence comprises blocks stored on the same track of a disk device. Deduplication may be performed using a block-comparison mechanism comprising metadata entries of stored blocks and a mapping mechanism containing mappings of deduplicated blocks to their matching blocks. The mapping mechanism may be used to perform later read requests received for the deduplicated blocks. The deduplication described herein may reduce the read latency as the number of seeks between tracks may be reduced. Also, when a seek to a different track is performed, the seek time cost is spread over THN or more blocks.

摘要： A system efficiently and proactively assesses the impact of user's actions on a network storage system. The system generally operates on a storage area network that includes a database represented by states and policies, before the user action is executed. The system comprises a storage monitor that captures a snapshot of the database states. An impact analysis module of the system then applies a user action to the snapshot; and further selectively applies at least some of the policies to the snapshot. The impact analysis module simulates the user action on the snapshot without applying actually changes to the database, and further analyzes whether the simulated user action violates at least one applied policy. The system takes the appropriate action based on the result of the analysis.

摘要： A distributed object store in a network storage system uses location-independent global object identifiers (IDs) for stored data objects. The global object ID enables a data object to be seamlessly moved from one location to another without affecting clients of the storage system, i.e., “transparent migration”. The global object ID can be part of a multilevel object handle, which also can include a location ID indicating the specific location at which the data object is stored, and a policy ID identifying a set of data management policies associated with the data object. The policy ID may be associated with the data object by a client of the storage system, for example when the client creates the object, thus allowing “inline” policy management. An object location subsystem (OLS) can be used to locate an object when a client request does not contain a valid location ID for the object.
摘要翻译： 网络存储系统中的分布式对象存储使用与存储的数据对象的位置无关的全局对象标识符（ID）。 全局对象ID使数据对象无缝地从一个位置移动到另一个位置，而不会影响存储系统的客户端，即“透明迁移”。 全局对象ID可以是多级对象句柄的一部分，其还可以包括指示存储数据对象的特定位置的位置ID，以及标识与数据对象相关联的一组数据管理策略的策略ID。 策略ID可以由存储系统的客户端与数据对象相关联，例如当客户端创建对象时，从而允许“内联”策略管理。 当客户机请求不包含对象的有效位置ID时，可以使用对象位置子系统（OLS）来定位对象。

摘要： Described herein is a system and method for dynamically managing service-level objectives (SLOs) for workloads of a cluster storage system. Proposed states/solutions of the cluster may be produced and evaluated to select one that achieves the SLOs for each workload. A planner engine may produce a state tree comprising nodes, each node representing a proposed state/solution. New nodes may be added to the state tree based on new solution types that are permitted, or nodes may be removed based on a received time constraint for executing a proposed solution or a client certification of a solution. The planner engine may call an evaluation engine to evaluate proposed states, the evaluation engine using an evaluation function that considers SLO, cost, and optimization goal characteristics to produce a single evaluation value for each proposed state. The planner engine may call a modeler engine that is trained using machine learning techniques.

摘要： Method and system for distributing a notification of an event occurring at a one entity to an affected entity. In one embodiment, entities are grouped into one or more groups so that an event occurring at one entity of the group is distributed to the other entities of the group (“affected entities”). If an event occurs at an entity managed by a local entity manager, a notification of the event can be routed to a remote entity manager that manages an affected entity. The local entity manager can use a distributed mapping to determine where to route the event notification. In one embodiment the mapping associates an entity to an entity manager.

摘要： Collaborative management of shared resources is implemented by a storage server receiving, from a first resource manager, notification of a violation for a service provided by the storage server or device coupled to the storage server. The storage server further receives, from each of a plurality of resource managers, an estimated cost of taking a corrective action to mitigate the violation and selects a corrective action proposed by one of the plurality of resource managers based upon the estimated cost. The storage server directs the resource manager that proposed the selected corrective action to perform the selected corrective action.

摘要： Graph transformations are used by a data management system to correct violations of service-level objectives (SLOs) in a data center. In one aspect, a process is provided to manage a data center by receiving an indication of a violation of a service-level objective associated with the data center from a server in the data center. A graph representation and a transformations data container are retrieved by the data management system from data storage accessible to the data management system. The transformations data container includes one or more transformations. The transformation is processed to create a mutated graph from a data center representation from the graph representation. An option for managing the data center is determined as a result of evaluating the mutated graphs.

摘要： A mechanism is provided to automatically retrieve zoning best practices from a centralized repository and to ensure that automatically generated zones do not violate these best practices. A user selects a set of hosts and storage controllers. The user also selects a guidance policy for creating the zone, and also selects a set of validation policies that must be enforced on the zone. If the user selects a guidance policy and a validation policy combination that is incompatible, the mechanism allows the user to change either the selected guidance policy or the set of validation policies. If the user has selected consistent-zoning as a guidance policy, then the mechanism automatically selects a guidance policy that does not violate the known validation policies.

摘要： A program storage device for managing resources in a storage system that is based on server resource usage is disclosed. The program storage device performs a method that allocates a command window to each of the servers accessing the resources, achieves an equilibrium state that balances the size of each server's command window and the amount of free resources, and maintains the equilibrium state by continually adjusting the size of each command window. The command window defines a limit on the number of outstanding storage requests that each server may maintain. The invention initially allocates a minimum sized command window.
