摘要： A digitally signed file system in which data, metadata and files are objects, each object having a globally unique and content-derived fingerprint and wherein object references are mapped by the fingerprints; the file system has a root object comprising a mapping of all object fingerprints in the file system, such that a change to the file system results in a change in the root object, and tracking changes in the root object provides a history of file system activity.

摘要： Method and apparatus for replicating data structures over a network in which each data structure is assigned an owner node among a plurality of networked peer nodes. Preferably that owner can be ascertained through information in the data structure. When an update to the data structure is desired by a non-owner, a request to modify the data structure is sent out on the network and when received by the owner, the owner performs the modification. The owner node can then notify the other nodes regarding the update. The method, implemented through a single-writer, multiple-reader paradigm, insures availability, partition tolerance and eventual consistency; it avoids the high overhead costs and single point of failure drawbacks of the prior art centralized management and locking protocols. Administrators can connect to any peer node in the network to manage, monitor and request modifications to a data structure.
摘要翻译：用于通过网络复制数据结构的方法和装置，其中每个数据结构在多个联网的对等节点之间分配所有者节点。优选地，可以通过数据结构中的信息来确定所有者。当非所有者希望对数据结构进行更新时，在网络上发送修改数据结构的请求，当所有者收到时，所有者执行修改。所有者节点可以通知其他节点有关更新。该方法通过单写入器多读取器范例实现，确保可用性，分区容限和最终一致性; 它避免了现有技术的集中管理和锁定协议的高开销成本和单点故障缺点。管理员可以连接到网络中的任何对等节点来管理，监视和请求修改数据结构。

摘要： Method and apparatus for constructing an index that scales to a large number of records and provides a high transaction rate. New data structures and methods are provided to ensure that an indexing algorithm performs in a way that is natural (efficient) to the algorithm, while a non-uniform access memory device sees IO (input/output) traffic that is efficient for the memory device. One data structure, a translation table, is created that maps logical buckets as viewed by the indexing algorithm to physical buckets on the memory device. This mapping is such that write performance to non-uniform access SSD and flash devices is enhanced. Another data structure, an associative cache is used to collect buckets and write them out sequentially to the memory device as large sequential writes. Methods are used to populate the cache with buckets (of records) that are required by the indexing algorithm. Additional buckets may be read from the memory device to cache during a demand read, or by a scavenging process, to facilitate the generation of free erase blocks.

摘要： Methods and systems are provided for tracking object instances stored on a plurality of network nodes, which tracking enables a global determination of when an object has no references across the networked nodes and can be safely de-allocated. According to one aspect of the invention, each node has a local object store for tracking and optionally storing objects on the node, and the local object stores collectively share the locally stored instances of the objects across the network. One or more applications, e.g., a file system and/or a storage system, use the local object stores for storing all persistent data of the application as objects.

摘要： Method and apparatus for storing records in non-uniform access memory. In various embodiments, the placement of records is localized in one or more regions of the memory. This can be accomplished utilizing different ordered lists of hash functions to preferentially map records to different regions of the memory to achieve one or more performance characteristics or to account for differences in the underlying memory technologies. For example, one ordered list of hash functions may localize the data for more rapid access. Another list of hash functions may localize the data that is expected to have a relatively short lifetime. Localizing such data may significantly improve the erasure performance and/or memory lifetime, e.g., by concentrating the obsolete data elements in one location. Thus, the two or more lists of ordered hash functions may improve one or more of access latency, memory lifetime, and/or operation rate.
