Abstract: An object management system comprises a computer system configured to store an object (72), which may be a file. The computer system is configured to divide the object (72) into partitions (70), select partitions, and provide the selected partitions to a storage device (14) for storage. The partitions are selected by determining which partitions need to be migrated device, based on whether the partitions have been modified. The system determines this by examining a data object associated with the object. The computer system may be configured to retrieve a selected partition from the storage device.

Abstract: In one example, a method may include performance of a hash function on a digital sequence so as to generate a hash value that corresponds to the digital sequence. Next, the digital sequence may be broken into data pieces, and each data piece hashed to produce a corresponding hash value for each data piece. Then, a recipe may be produced that includes instructions which, when executed, may generate the digital sequence from the data pieces referenced by their corresponding hash values included in the recipe. Among other things, the hash values may enable reutilization of redundant data sequences by serving as pointers to the data pieces that the hash values respectively represent.

According to one aspect, the subject matter described herein includes a method for dynamic, policy-based allocation of system resources. The method includes specifying a plurality of system resource collections for representing sets of like system resources and their dependencies. An order in which the collections are to be evaluated during selection of a resource is also specified. A policy for determining the best resource within each collection is also specified. Statistics about the system resources in the collections are maintained. A request for a resource is received. In response to receiving the request, the collections are evaluated in the specified order. The best resource is selected from each collection based on the dependencies, prior selections, and statistics to implement the policy.

Abstract: The operation of a data storage system is controlled by determining dimensions of a situational state space characterizing operating conditions of the data storage system, associating policy sets with respective states of the state space, monitoring system operation in the state space, selecting a particular one of the policy sets based on an identified current state in the state space, and controlling the operation of the system in accordance with the selected policy set. These operations are performed by a processing device incorporated in or otherwise associated with the system, with the processing device implementing a situational analysis framework comprising a learning module coupled to a production module. The situational analysis framework may be part of a policy engine. The dimensions of the situational state space in an illustrative embodiment may comprise two or more dimensions selected from one or more dimension categories such as load, performance, time and event state.

The first user may provide the voucher code to a second user, responsive to a request by the second user for the first user to vouch for the second user, to thereby allow the second user to be authenticated. The authentication server receives the voucher code from the second user, and authenticates the second user based on the voucher code. The authenticated second user may be provided with a temporary password or other type of code utilizable for at least one additional authentication.

Abstract: Discovering environment objects for information management in a networked environment. Information management provides services such as data protection, backup, retention, compliance, etc., by classifying the objects and/or infrastructure of an entity according to its value to the entity. Information management begins by discovering the data in a network and by discovering the servers and services operating in a network. The servers and services are discovered using adapters that can collect information regarding the environment objects. This information can then by used by information management systems to assign or orchestrate various services.

Abstract: A transaction system combats malware and phishing-based MitM attacks on transaction processing systems by using digital signatures to integrity-protect the user-verified transaction data. With this system, a user submits a transaction from a client device (e.g., desktop web browser) over a communications channel to a server device, such as a transaction server. Before accepting the transaction, the transaction server securely delivers all relevant transaction data to a second device (e.g., the signing device), such as a smart phone, in the possession of the user. The signing device has its own distinct communication channel with the server device. The user verifies the data and the signing device creates a digital signature value for the transaction. The user submits the signature to the transaction server to confirm the transaction with the transaction server.

A command from the client device may be passed among first processors and peer processors of the multiple storage processor systems until the correct destination processor for the command is reached, and data packets may be passed from a source processor of a storage processor system through processors of other storage processor systems until the client device is reached.

Abstract: Storage requirements of one or more applications may be serviced by a mix of different disk technologies across one or more storage tiers. According to the system described herein, desirable or optimal mixes of the different disks may be determined and used in the efficient and cost-effective modification or upgrade of storage arrays. For example, whereas SATA drives may be the most cost effective per gigabyte of storage, some applications may not be able to operate based on SATA performance characteristics. On the other hand, flash drives, which may have high performance characteristics, may be too expensive to be used exclusively in a storage array. The system described herein provides a tool that allows for optimal planning of storage resources in a multi-tier storage environment responsive to workload data of a storage array and based on performance characteristics and costs of the storage resources.

Abstract: Described are techniques for processing a data operation in a data storage system. A front-end component receives the data operation to read a data portion. In response to receiving the data operation, the front-end component performs first processing. The first processing includes determining whether the data operation is a read operation resulting in a cache hit to a prefetched data portion of a sequential stream, and if said determining determines that said data operation results in a cache hit to a prefetched data portion, performing processing in connection with prefetching additional data for said sequential stream. The processing includes determining whether to prefetch additional data for said sequential stream and, if so, an amount of additional data to prefetch. The processing uses one or more criteria to determine one or more of an amount of data to prefetch in a single prefetch request and a track ahead parameter.
