Abstract: 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.

Abstract: Techniques and systems for storing and retrieving data storage devices of a data storage system are disclosed. In some embodiments, inventory holders are used to store data storage devices used by a data storage system. When data is to be transacted with the data storage devices, mobile drive units locate appropriate inventory holders and transport them to a device reading station, where an appropriate device retrieval unit transacts the data. In some embodiments, each inventory holder includes a plurality of trays that are independently accessible to the device retrieval unit. After the data has been transacted, the data storage devices are returned to the appropriate inventory holders, and the inventory holders are placed by the mobile drive units in locations where they may be accessed in response to further data transactions.

Abstract: Techniques for exploiting variable media sizes to create new redundancy encoded data storage systems are described herein. A set of storage devices is selected based at least in part on each storage device having an available capacity and, using the set of storage devices, a set of shards for a redundancy encoded data storage system is generated such that each shard of the set of shards has a storage capacity corresponding to the minimum available capacity of the set of storage devices.

Abstract: If none of the fragments of an erasure-coded data file have become corrupted then the original data file can be readily reconstructed. If one or more fragments of an erasure-coded data file have become corrupted it may still be possible to find a combination of fragments that reconstruct the original data file, but the number of possible combinations may be impracticably large. If an attempt with a first set of fragments fails, an efficient approach is to use an independent set of fragments for the second attempt. Then, for further attempts, the results of a current attempt are compared with previous results. If a match is found then the original data file has been reconstructed. An original data file may also be reconstructed by separately recovering each data block of the data file from corresponding fragment blocks and assembling the data file from the recovered data blocks.
Abstract translation: 如果擦除编码的数据文件的片段都没有被破坏，则可以容易地重构原始数据文件。 如果擦除编码的数据文件的一个或多个片段已经被破坏，则仍然可能找到重建原始数据文件的片段的组合，但是可能的组合的数量可能是不切实际的。 如果尝试使用第一组片段失败，则有效的方法是使用独立的片段来进行第二次尝试。 然后，为了进一步尝试，将当前尝试的结果与先前的结果进行比较。 如果发现匹配，则原始数据文件已被重构。 原始数据文件也可以通过从相应的分段块单独地恢复数据文件的每个数据块并从恢复的数据块组装数据文件来重建。

Abstract: Aspects of a data environment, such as the creation, provisioning, and management of data stores and instances, are managed using a separate control environment. A user can call into an externally-facing interface of the control environment, the call being analyzed to determine actions to be performed in the data environment. A monitoring component of the control plane also can periodically communicate with the data environment to determine any necessary actions to be performed, such as to recover from faults or events in the data environment. A workflow can be instantiated that includes tasks necessary to perform the action. For each task, state information can be passed to a component in the data environment operable to perform the task, until all tasks for an action are completed. Data in the data environment can be accessed directly using an externally-facing interface of the data environment, without accessing the control plane.
Abstract translation: 使用单独的控制环境来管理诸如数据存储和实例的创建，配置和管理等数据环境的各个方面。 用户可以调用控制环境的面向外部的接口，分析呼叫以确定要在数据环境中执行的动作。 控制平面的监视组件还可以周期性地与数据环境进行通信，以确定要执行的任何必要的动作，例如从数据环境中的故障或事件中恢复。 可以实例化工作流，其中包括执行操作所需的任务。 对于每个任务，可以将状态信息传递到可操作以执行任务的数据环境中的组件，直到完成操作的所有任务。 数据环境中的数据可以直接使用数据环境的面向外部的接口进行访问，而无需访问控制平面。

Abstract: A data storage service stores a dataset on a set of storage nodes in accordance with a first encoding. A set of shards constituting quorum, and one or more additional shards, are stored on the storage nodes. The data storage system determines to store the dataset according to a second encoding, in which the second encoding has fewer total shards. The data storage system reconfigures the storage of the dataset in accordance with the second encoding, such that the reconfigured storage comprises subsets of shards from the first encoding that were not re-encoded in forming the second encoding.

Abstract: 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 randomly (or otherwise) 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 retrieve an object from a cohort, a subset of the nodes may be queried; the subset may be randomly or otherwise selected. If enough data elements are retrieved for the object from the queried nodes, the object is provided to the requester. Otherwise, additional data elements may be retrieved according to the metadata returned with a data element or by querying additional nodes.
