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： 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： This invention is a system and a method for operating a storage server to provide read or write access to a data in a data network using a new architecture. The method of creating virtual block mapping pointer in response to a request by a client of the storage server to de-duplicate the file system data block or to allow compression of one or more file system data blocks into one or more physical data blocks. Further, the method relocates one or more file system data blocks from one part of the file system address space to another by using one or more virtual block mapping pointers that provides the mapping information for the one or more file system data blocks that are being relocated. The virtual block mapping pointer allows relocating of file system data blocks by same number of metadata operations regardless of number of files sharing the block that are being relocated and the state of those blocks (compressed or not).

摘要： A snapshot copy facility maintains information indicating block ownership and sharing between successive versions by delegating block reference counts to parent-child relationships between the file system blocks, as indicated by block pointers in inodes and indirect blocks. When a child block becomes shared between a parent block of the production file and a parent block of a snapshot copy, the delegated reference count is split among the parent blocks. This method is compatible with a conventional data de-duplication facility, and avoids a need to update block reference counts in block metadata of child blocks of a shared indirect block upon splitting the shared indirect block when writing to a production file.

摘要： A method is used in managing global data caches for file systems. Space is allocated in a volatile memory of a data storage system to a global data cache that is configured to store a set of data objects for a plurality of different file systems. The set of data objects is accessed by the plurality of different file systems. Contents of a file of a file system are stored in a data object in the global data cache upon receiving a write I/O request for the file. A copy of the data object and information for the data object are stored in a persistent journal that is stored in a non-volatile memory of the data storage system. Contents of the file are updated on a storage device based on the data object stored in the global data cache and information stored in the persistent journal.
