摘要： One embodiment retrieves a first portion of a plurality of stored objects from at least one storage device. The embodiment further performs a base type deduplication estimation process on the first portion of stored objects. The embodiment still further categorizes the first portion of the plurality of stored objects into deduplication sets based on a deduplication relationship of each object of the plurality of stored objects with each of the estimated first plurality of deduplication chunk portions. The embodiment further combines deduplication sets into broad classes based on deduplication characteristics of the objects in the deduplication sets. The embodiment still further classifies a second portion of the plurality of stored objects into broad classes using classifiers. The embodiment further selects an appropriate deduplication approach for each categorized class.

摘要： A system and associated method for optimizing power consumption of a data center by dynamic workload adjustment. A current workload distribution of the data center is shifted to an optimal workload solution that provides acceptable level of service with the least amount of power consumption. The sum of power cost and migration cost that corresponds to the optimal workload solution is the lowest among all sums that correspond to respective candidate workload solutions. The power cost is determined by a maximum temperature of the data center and accompanying cooling cost for each candidate workload solution. The migration cost is determined by performance degradation that occurs during shifting a workload distribution of the data center from the current workload distribution to each candidate workload solution.

摘要： A system and associated method for replicating data based on capacity optimization. A local node receives the data associated with a key. The local node within a local domain communicates with nodes of remote domains in a system through a communication network. Each domain has its own distributed hash table that partitions key space and assigns a certain key range to an owner node within the domain. For new data, the local node queries owner nodes of domains in the system progressively from the local domain to remote domains for a duplicate of the new data. Depending on a result returned by owner nodes and factors for replication strategies, the local node determines a replication strategy and records the new data in the local node pursuant to the replication strategy.

摘要： Embodiments of the present invention provide an approach that utilizes discrete event simulation to quantitatively analyze the reliability of a modeled de-duplication system in a computer storage environment. In addition, the approach described herein can perform such an analysis on systems having heterogeneous data stored on heterogeneous storage systems in the presence of primary faults and their secondary effects due to de-duplication. In a typical embodiment, data de-duplication parameters and a hardware configuration are received in a computer storage medium. A data de-duplication model is then applied to a set of data and to the data de-duplication parameters, and a hardware reliability model is applied to the hardware configuration. Then a set (at least one) of discrete events is simulated based on the data de-duplication model as applied to the set of data and the data de-duplication parameters, and the hardware reliability model as applied to the hardware configuration. Based on the simulation, a set of data reliability and availability estimations/estimates can be generated (e.g., and outputted/provided).

摘要： A system and associated method for continuously optimizing data archive management scheduling. A job scheduler receives, from an archive management system, inputs of task information, replica placement data, infrastructure topology data, and resource performance data. The job scheduler models a flow network that represents data content, software programs, physical devices, and communication capacity of the archive management system in various levels of vertices according to the received inputs. An optimal path in the modeled flow network is computed as an initial schedule, and the archive management system performs tasks according to the initial schedule. The operations of scheduled tasks are monitored and the job scheduler produces a new schedule based on feedbacks of the monitored operations and predefined heuristics.
