    Abstract: Scheduling operations such as asynchronous file system operations in a network storage system is accomplished by applying a bid-price online auction methodology, in which bid (willingness-to-pay) values and price (cost) values are dynamically set by storage clients and a storage server, respectively, based on utilization of computing resources. The system provides a framework for adaptively scheduling asynchronous file system operations, managing multiple key resources of the distributed file system, including network bandwidth, server I/O, server CPU, and client and server memory utilization. The system can accelerate, defer, or cancel asynchronous requests to improve application-perceived performance. Congestion pricing via online auctions can be employed to coordinate the use of system resources by clients, so clients can detect shortages and adapt their resource usage.

    Abstract: A live non-volatile (NV) replay technique enables a partner node to efficiently takeover a failed node of a high-availability pair in a multi-node storage cluster by dynamically replaying operations synchronously logged in a non-volatile random access memory (NVRAM) of the partner node, while also providing high performance during normal operation. Dynamic live replay may be effected through interpretation of metadata describing the logged operations. The metadata may specify a location and type of each logged operation within a partner portion of the NVRAM, as well as any dependency among the logged operation and any other logged operations that would impose an ordering constraint. During normal operation, the partner node may consult the metadata to identify dependent logged operations and dynamically replay those operations to satisfy one or more requests. Upon failure of the node, the partner node may replay, in parallel, those logged operations having no imposed ordering constraint, thereby reducing time needed to complete takeover of the failed node.

    Abstract: The present invention provides a system and a method for utilizing a parity protection module to back up data on striped aggregates. Specifically, the system computes party data for data stored at a particular location of each of a plurality of constituent aggregates, and stores the parity on one of the constituent aggregates that is a parity owner for that particular location of data. In the event one of the constituent aggregates fails, new data may still be accessed by the system (the striped aggregates), both to write new data, and to read data stored on the failed aggregate. In particular, the parity protection module allows clients to read data from a failed aggregate by running a reverse parity computation, which may also be used to restore the data to the failed aggregate.

    Abstract: A network-accessible memory (NAM) element comprises a substrate, a memory mounted to the substrate, network interface circuitry and logic circuitry. The network interface circuitry implements a network physical layer and is mounted to the substrate. The logic circuitry is mounted to the substrate and is coupled to the network interface circuitry and the memory, and is configured to operate as a memory controller to control access to the memory by a host processor which is external to the NAM element through the network interface circuitry. The NAM element can be interconnected with other NAM elements to form a larger NAM storage device.
