摘要： Methods and systems for conveying or transmitting to any given user in an OFDMA-MU-MIMO system scheduling information of other co-scheduled users to permit the user to perform error-correction on received data and/or interference reduction on its received signals. The scheduling information can include resource block assignment, modulation constellations employed, coding rates employed, power levels utilized and precoder matrix indices used. Further, the scheduling information can be conveyed in part through dedicated reference symbol layers or pilot streams. Moreover, a base station may transmit a preliminary estimate of the total number of users the base station expects to schedule, or an upper-bound on the total number of users, to the MU-MIMO users to permit the MU-MIMO users to determine preferred precoder matrix indices and indications of channel quality indices.

摘要： A system and method for prioritizing alerts includes extracting invariants to determine a stable set of models for determining relationships among monitored system data. Equivalent thresholds for a plurality of rules are computed using an invariant network developed by extracting the invariants. For a given time window, a set of alerts are received from a system being monitored. A measurement value of the alerts is compared with a vector of equivalent thresholds, and the set of alerts is ranked.

摘要： Data is stored in a distributed data storage system comprising a plurality of disks. When a disk fails, system reliability is restored by executing a set of reconstructions according to a schedule. System reliability is characterized by a dynamic Normalcy Deviation Score. The schedule for executing the set of reconstructions is determined by a minimum intersection policy. A set of reconstructions is received and divided into a set of queues rank-ordered by redundancy level ranging from a lowest redundancy level to a highest redundancy level. For reconstructions in each queue, an intersection matrix is calculated. Diskscores for each disk are calculated. The schedule for the set of reconstructions is based at least in part on the intersection matrices, the Normal Deviation Scores, and the diskscores.

摘要： Information, such as files received from a client, etc. is stored in a storage system, such as a content addressable storage system. A file server receives data from a client and chunks the data into blocks of data. The file server also generates metadata for use in forming a data structure. The blocks of data are stored in a block store and a copy of the data blocks and the metadata are locally cached at the file server. A commit server retrieves the metadata. In at least one embodiment, the metadata is retrieved from an update log shared between the file server and the commit server. Based on the retrieved metadata, the commit server generates a version of a data structure. The data structure is then stored at the block store.

摘要： In accordance with exemplary embodiments of the present invention, a content addressable data structure system may include directed acyclic graphs (DAGs) of data content that are addressed using both a user-defined search key and content of data blocks. Internal keys of retention roots of the DAGs may be derived from the user-defined search key while the remaining blocks may be content addressed. As opposed to using a content address, the user may provide the search key when retrieving and deleting DAGs retaining the data content. In addition, the internal keys may be implemented using internal content addressable storage operations, such as applying a hash function and employing a distributed hash table.
