摘要： This invention is a system and a method for operating a storage server that provides read or write access to a data in a data network using a new architecture. The method of processing I/Os in response to a request by a client of the storage server executes one or more services communicated by a policy engine. The I/Os received from the application are tagged and catalogued to create co-related I/O patterns. The policy engine is then updated with the results of processing the I/Os after executing services on those I/Os.

摘要： Based on a count of the number of dirty pages in a cache memory, the dirty pages are written from the cache memory to a storage array at a rate having a component proportional to the rate of change in the number of dirty pages in the cache memory. For example, a desired flush rate is computed by adding a first term to a second term. The first term is proportional to the rate of change in the number of dirty pages in the cache memory, and the second term is proportional to the number of dirty pages in the cache memory. The rate component has a smoothing effect on incoming I/O bursts and permits cache flushing to occur at a higher rate closer to the maximum storage array throughput without a significant detrimental impact on client application performance.
摘要翻译：基于高速缓冲存储器中脏页数的计数，脏页以高速缓冲存储器中的脏页数的变化率成比例的速率从高速缓冲存储器写入存储阵列。例如，通过将第一项添加到第二项来计算所需的刷新速率。第一项与高速缓冲存储器中脏页数的变化率成比例，第二项与高速缓冲存储器中的脏页数成比例。速率组件对传入的I / O突发具有平滑效果，并允许高速缓存刷新以更高的速率发生，更接近最大存储阵列吞吐量，而不会对客户端应用程序性能造成重大的不利影响。

摘要： Interrupts and code threads are assigned in a particular way to the core CPUs of a network file server in order to reduce latency for processing client requests for file access. Threads of the network stack are incorporated into real time threads that are scheduled by a real-time scheduler and executed exclusively by a plurality of the core CPUs that are not interrupted by disk adapter interrupts so that the disk adapter interrupts do not interrupt execution of the network stack. Instances of a storage access driver are hard affinity threads, and soft affinity threads include a multitude of instances of a thread of the file system stack for file access request processing so that file access request processing for a multitude of concurrent file access requests is load balanced over the core CPUs.

摘要： A file server system having solid-state drive primary storage and magnetic disk drive secondary storage aggressively moves newly created files from the primary storage to selected file systems in the secondary storage to match expected access patterns upon the files to different configurations of the file systems and for load balancing upon the file systems in the secondary storage. Upon read access to a file that has been moved to the secondary storage, or upon migration of a newly created file that was read in primary storage after creation, a corresponding stub file containing file mapping metadata is created in the primary storage. The file mapping metadata in the stub file maps the extent of the file to logical storage addresses in the secondary storage.

摘要： Interactive requests are processed from users of log-in nodes. A metadata server node is provided for use in a file system shared by one or more interactive nodes and one or more batch nodes. The interactive nodes comprise interactive clients to execute interactive tasks and the batch nodes execute batch jobs for one or more batch clients. The metadata server node comprises a virtual machine monitor; an interactive client proxy to store metadata requests from the interactive clients in an interactive client queue; a batch client proxy to store metadata requests from the batch clients in a batch client queue; and a metadata server to store the metadata requests from the interactive client queue and the batch client queue in a metadata queue based on an allocation of resources by the virtual machine monitor. The metadata requests can be prioritized, for example, based on one or more of a predefined policy and predefined rules.

摘要： A file server includes active storage containing frequently accessed files, and active/inactive disk drives for containing infrequently accessed files. Groups of the files having become inactive in the active storage are successively migrated to respective evacuated active/inactive disk drives so that each active/inactive disk drive is loaded with files having a similar probability of access when access to the active/inactive disk drive reaches an inactivity threshold for powering down the active/inactive disk drive. Storage of the active/inactive disk drives is reclaimed when an oldest group of the files is archived or when an active/inactive disk drive is evacuated by migrating files from the active/inactive disk drive to storage having been released in other disk drives by promotion of files for client access to the promoted files. Therefore, recovery of storage can be planned and scheduled in advance and performed efficiently in a background process.

摘要： Embodiments of the present invention are directed to techniques for selecting a data path over which to exchange information between a client device and a storage system by making a selection between a file system server (NAS) data path type (a first data path type) and a direct (SAN) data path type (a second data path type) based on one or more adjustable path selection factors and/or information regarding components of the computer system. For example, a data path may be selected based on one or more performance characteristics of a computer system in which a path selection module is acting and/or any other suitable path selection factor.
