摘要： Cohorts may be created on storage nodes in an object-redundant storage system that uses replication and/or a redundant encoding technique. In a cohort with N nodes, M data elements (replicas or shards) of an object are stored to M of the nodes that are selected from the N nodes. Metadata for locating other data elements for an object in the cohort may be stored with one or more of the data elements in the cohort. To reconcile the nodes, common object lists are generated on each node for at least one other node from the metadata, hashes of the lists may be exchanged among the nodes, and the hashes are compared. If the hashes for two nodes differ, specific differences are determined, and a reconciliation process performs reconciliation based on the determined differences.

摘要： Systems and methods are described for rotating keys in a trust store to be used by a group of peer devices for secure communications between the peers in the group. In some examples, a service, such as an identify authority service, may make a determination that a set of peers that individually trust at least one public key from a group of public keys satisfies a set of conditions. As a result of the determination, the service may update the plurality of public keys by at least removing at least one public key from the group of public keys and indicate the updated plurality of public keys to at least one of the peers in the group. The service may remove the at least one public key from the group upon determining that less than a threshold number of peers in the group use the at least one public key.

摘要： A switching device is implemented in a network-attachable data transfer device to provide data storage access to other such devices. In some embodiments, network-attachable data transfer devices are arranged in a clustered configuration to provide various computational and storage services. When one or more devices of the cluster fails, various implementations associated with the switching device, via an external data interface, provide operational mitigation, optimized data recovery, and efficient reinstatement of normal operation of the cluster.

摘要： A data center may include a tape library rack module along with rack computer systems. The rack computer systems may be configured to provide computing capacity within a data center environment. In some embodiments, the tape library rack module may include an enclosure encompassing an interior of the tape library rack module, a rack within the interior, and a tape library unit mounted on the rack. The tape library rack unit may include tape cartridges configured to store data within a tape environment that is different than the data center environment. The tape library rack unit may be within a portion of the interior that is enclosed such that it is environmentally isolated from the data center environment. In some examples, the tape library rack module may include a cooling unit and/or a humidifier unit, which may provide the tape environment to the environmentally isolated portion of the interior of the tape library rack module.

摘要： Techniques described and suggested herein include systems and methods for storing, indexing, and retrieving original data of data archives on data storage systems using redundancy coding techniques. For example, redundancy codes, such as erasure codes, may be applied to archives (such as those received from a customer of a computing resource service provider) so as allow the storage of original data of the individual archives available on a minimum of volumes, such as those of a data storage system, while retaining availability, durability, and other guarantees imparted by the application of the redundancy code. Sparse indexing techniques may be implemented so as to reduce the footprint of indexes used to locate the original data, once stored.
