摘要： Improved logging techniques that produce transaction logs are disclosed. The logging techniques are able to consolidate multiple related partial operations performed on a server device into a single log entry in a transaction log. Accordingly, the logging techniques are well suited for logging operations of protocols in which transactions are often completed over multiple operations. The logging techniques are particularly well suited for logging access to NFS file and/or directory resources with respect to a NFS server, even when the NFS operations are performed via Remote Procedure Calls (RPCs) to the NFS server.

摘要： A system and method for coordinating a point-in-time copy (PITC) of a file or set of data distributed (e.g., striped) across multiple data providers (e.g., filers, file servers, storage arrays). A service coordinator receives a PITC request for a parent file, initializes the PITC's metadata and instructs the data providers to generate PITC subcomponents for the portions (e.g., sub-mirrors) of the file that they store. A scoreboard is created to track the status of the PITC, and includes an entry for each PITC subcomponent. Quality of service characteristics for the PITC may be copied from the parent and/or received with the request. If those characteristics cannot be attained, the PITC may be aborted. As PITC subcomponents are completed, they are returned to the service coordinator for assembly of the PITC.

摘要： A frame-address matching function of a network controller is enhanced. In a full power-on mode, the controller performs conventional functions. In the low-power mode, the controller includes frame-address and frame-data matching, as well as pre-determined and programmable autonomous response to network protocol. If a match occurs with respect to the frame destination address or frame data, the system associated with the controller is placed in a wake-up state. If the controller is programmed to perform pattern matching inside the frame data area, upon such match in the frame data area the controller will generate and transmit on the network a simple response packet automatically. Conversely, if a match is not detected, no action is taken. The frame-data patterns are programmable with the capability to mask out certain data fields as desired which are protocol dependent and are substantially protocol dependent.

摘要： A file is striped across multiple filers, file servers or other devices, to create a sparsely striped multi-component file. Each filer stores one sparse component. In particular, each component physically stores only those stripes allocated to that component. The other stripes are represented as holes. Thus, instead of contiguously packing each component's stripes at the block level, each component is a file having the same logical structure. A component of a sparsely striped multi-component file can be easily converted to a mirror by filling in its holes. Similarly, a mirror can be easily converted to one component of a sparsely striped multi-component file by removing or ignoring it unallocated stripes. In either case, the layout or logical of the component does not need to be reconfigured.

摘要： A system and method for decreasing the protocol processing incurred by an NFS (Network File System) client, and the network bandwidth consumed, when multiple NFS requests are issued close in time to each other. Requests received close in time to each other within one NFS client are aggregated into a single communication packet, even if they are from different NFS users, processes or applications. The per-request overhead of the NFS requests is thus avoided, and multiple streams of requests may be merged into one. When a first request is received by the client, it may be delayed for a short time to determine whether any other requests can be sent at the same time. NFS requests may be aggregated on an NFS client from multiple applications, processes, users or other entities. An NFS client may include an aggregator or other mechanism for performing the aggregation.
摘要翻译： 当多个NFS请求在时间上相互发出时，减少由NFS（网络文件系统）客户端引起的协议处理以及消耗的网络带宽的系统和方法。 一个NFS客户端内的时间接近的请求被聚合成单个通信包，即使它们来自不同的NFS用户，进程或应用程序。 因此避免了NFS请求的每请求开销，并且可以将多个请求流合并成一个。 当客户端收到第一个请求时，可能会延迟很短的时间，以确定是否可以同时发送其他请求。 NFS请求可以在多个应用程序，进程，用户或其他实体的NFS客户端上聚合。 NFS客户端可以包括用于执行聚合的聚合器或其他机制。

摘要： A system and method for emulating the input/output performance of an application. A workload description language is used to produce a small but accurate model of the application, which is flexible enough to emulate the application's performance with varying underlying system configurations or operating parameters. The model describes I/O operations performed by the application, and reflects any dependencies that exist between different application threads or processes. The model is then executed or interpreted with a particular system configuration, and various parameters of the I/O operations may be set at the model's run-time. During execution, the input/output operations described in the model are generated according to the specified parameters, and are performed. The system configuration and/or I/O operation parameters may be altered and the model may be re-run.
