摘要： Methods, apparatus, and computer-accessible storage media for optimizing block storage I/O operations in a storage gateway. A write log may be implemented in a block store as a one-dimensional queue. A read cache may also be implemented in the block store. When non-ordered writes are received, sequential writes may be performed to the write log and the data may be written to contiguous locations on the storage. A metadata store may store metadata for the write log and the read cache. Reads may be satisfied from the write log if possible, or from the read cache or backend store if not. If blocks are read from the read cache or backend store to satisfy a read, the blocks may be mutated with data from the write log before being sent to the requesting process. The mutated blocks may be stored to the read cache.

摘要： Techniques for implementing a data management scheme for optimizing data storage are described herein. A deletion quantity or other metric relating to deletions of data within a first storage zone are tracked. Upon detection that the tracked deletion metric meets certain criteria, the data within the first storage zone are moved to a second storage zone. A verification of the data to be moved is also performed, and if such verification indicates that at least a portion of the data is corrupted, routines repairing and/or restoring at least the corrupted portion are initiated.

摘要： A device is described for assisting network technicians and other users with network cabling. The device can be provided to a technician, where the technician plugs a loose cable end into the device, and if the other end of the cable is attached to a switch (e.g. Euclid switch), the device indicates to the technician via a display where on the network the cable should be plugged in (which port on which switch). When the device is connected to a switch via a cable, the switch can make available its information to the device. The device can also consult a data store to determine where the other end should be attached. The information that is used to determine where the cable should be attached can include the number of layers in the network; the number of switches in each layer; and the number of ports on the switches.

摘要： A distributed, web-services based storage system. A system may include a web services interface configured to receive, according to a web services protocol, a given client request for access to a given data object, the request including a key value corresponding to the object. The system may also include storage nodes configured to store replicas of the objects, where each replica is accessible via a respective unique locator value, and a keymap instance configured to store a respective keymap entry for each object. For the given object, the respective keymap entry includes the key value and each locator value corresponding to replicas of the object. A coordinator may receive the given client request from the web services interface, responsively access the keymap instance to identify locator values corresponding to the key value and, for a particular locator value, retrieve a corresponding replica from a corresponding storage node.

摘要： Methods and apparatus for receiving uploaded data from a sender at a receiver. A data deduplication technique is described that may reduce the bandwidth used in uploading data from the sender to the receiver. In the technique, the receiver, rather than the sender, maintains a fingerprint dictionary for previously uploaded data. When a sender has additional data to be uploaded, the sender extracts fingerprints for units of the data and sends the fingerprints to the receiver. The receiver checks its fingerprint dictionary to determine the data units to be uploaded and notifies the sender of the identified units, which then sends the identified units of data to the receiver. The technique may, for example, be applied in virtualized data store systems to reduce bandwidth usage in uploading data.

摘要： Systems and methods for managing mapping information for objects maintained in a distributed storage system are provided. The distributed storage system can include a keymap subsystem that manages the mapping information according to object keys. Requests for specific object mapping information are directed to specific keymap coordinators within the keymap subsystem. Each keymap coordinator can maintain a cache for caching mapping information maintained at various information sources. To manage the cache, the keymap system can utilize generation identifiers that identify the component within the distributed storage system that last updated information sources. Each keymap coordinator can determine whether cached version of keymap information is valid based on an analysis of generation identifiers.

Requests for specific object mapping information are directed to specific keymap coordinators within the keymap subsystem.

摘要： Dynamic object replication in distributed storage systems. A system may implement a web services interface, storage nodes, storage node selection logic and a coordinator. The web services interface may be configured to receive, according to a web services protocol, client requests to store data objects including a given client request to store a given one of the data objects. The storage nodes may be configured to store replicas of the data objects. The storage node selection logic may be configured to dynamically determine a write plan for storing replicas of the given data object to corresponding storage nodes, where the write plan is dynamically determined according to current state information of the storage nodes. The coordinator may be configured to receive the client requests from the web services interface, and for the given client request, to store the replicas of the given data object to the corresponding storage nodes according to the write plan.
