摘要： Automatic network configuration of cluster paths to access data within a cluster is described. Each node of the cluster presents to clients an image of the cluster as a single system. Each node also stores information regarding what node has particular data, as well as information about network addresses and corresponding network capabilities for the various network addresses for each node. When a node receives a request for data, the node determines a node where the request data can be accessed, determines network addresses and network capabilities for each network address of the node, and selects a path to access the node based on the determined information. The receiving node may select the path based on network type and capability, as well as load and performance of the network.

摘要： Systems and methods for efficiently using solid-state devices are provided. Some embodiments provide for a data processing system that uses a non-volatile solid-state device as a circular log, with the goal of aligning data access patterns to the underlying, hidden device implementation, in order to maximize performance. In addition, metadata can be interspersed with data in order to align data access patterns to the underlying device implementation. Multiple input/output (I/O) buffers can also be used to pipeline insertions of metadata and data into a linear log. The observed queuing behavior of the multiple I/O buffers can be used to determine when the utilization of the storage device is approaching saturation (e.g., in order to predict excessively-long response times). Then, the I/O load on the storage device may be shed when utilization approaches saturation. As a result, the overall response time of the system is improved.

摘要： A persistent cache is implemented in a flash memory that includes a journal section that stores metadata and a low frequency section and a high frequency section that store data entries. Writing new metadata to the persistent cache includes sequentially advancing to a next sector containing an invalid metadata entry, saving a working copy of the sector in RAM, writing metadata corresponding to one or more new data entries in the working copy, and overwriting the sector in the flash memory containing the invalid entry with the working copy. Writes to the low frequency and high frequency sections occur sequentially in the current locations of a low frequency section pointer and a high frequency section pointer, respectively. In a persistent cache, the reconstruction of a non-persistent cache utilizes the metadata entry that has the most recent timestamp.

摘要： One or more techniques and/or systems are provided for performing host side deduplication. Host side deduplication may be performed upon writeable data within a write request received at a host computing device configured to access data stored by a storage server. The host side deduplication may be performed at the host computing device to determine whether the writeable data is already stored by the storage server based upon querying a host side cache comprising data stored by a storage server and/or a data structure comprising unique signatures of data stored by the storage server. If the writeable data is stored by the storage server, then a deduplication notification excluding the writeable data may be sent to the storage server, otherwise a write command comprising the writeable data may be sent. Accordingly, unnecessary network traffic of redundant data already stored by the storage server may be reduced.
摘要翻译：提供一个或多个技术和/或系统用于执行主机端重复数据删除。主机重复数据删除可以在被配置为访问由存储服务器存储的数据的主计算设备接收的写请求内的可写数据上执行。可以在主机计算设备处执行主机重复数据删除，以基于查询包含由存储服务器存储的数据的主机侧缓存器和/或包括唯一的数据签名的数据结构来确定存储服务器是否已经存储了可写数据由存储服务器存储。如果存储服务器存储可写数据，则可以向存储服务器发送排除可写数据的重复数据消除通知，否则可以发送包含可写数据的写命令。因此，可以减少由存储服务器已经存储的冗余数据的不必要的网络流量。

摘要翻译：提供了有效使用固态器件的系统和方法。一些实施例提供了使用非易失性固态设备作为循环日志的数据处理系统，其目的是将数据访问模式对准底层的隐藏设备实现，以便最大化性能。此外，元数据可以散布数据，以便将数据访问模式与底层设备实现对齐。多个输入/输出（I / O）缓冲区也可用于将元数据和数据流插入线性日志。可以使用多个I / O缓冲器观察到的排队行为来确定存储设备的利用率何时接近饱和（例如，为了预测过长的响应时间）。然后，当利用率接近饱和时，存储设备上的I / O负载可能会流失。结果，系统的整体响应时间得到改善。
