摘要： A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes taking a snapshot of a physical volume with a native snapshot program, determining which blocks have changed since a previous snapshot with a change block tracker, creating a child virtual container, populating the child virtual container with the changed blocks, and linking the child virtual container with a parent virtual container.

摘要： Dynamically adjusting a block size in a data transfer operation is disclosed. An indication that a data transfer operation has commenced is received. A first portion of data is read using a first read block size. A first throughput associated with the first read block size is determined. A second portion of data that is different from the first portion of data is read using a second block size that is different from the first read block size. One of the first and second read block sizes is used to complete the data transfer operation based on a comparison of the first throughput and a throughput of the second read block size. This process can be repeated several times as necessary.

摘要： A method and system for providing shared access to a target storage device by multiple clients through one or more network storage nodes. A network server includes control interfaces to the one or more storage nodes and executes logic processes that control the node processes. The logic processes contain definitions of the storage nodes, maps of which storage nodes have access to the desired target storage, and assigns the preferred storage nodes to the client upon request. Each storage node implements a dynamic volume sharing process that replaces existing monolithic daemon processes and allows for scalability of backup/restore operations and concurrent execution of different storage access operations and different types of storage access operations.
摘要翻译：一种用于通过一个或多个网络存储节点向多个客户机提供对目标存储设备的共享访问的方法和系统。网络服务器包括到一个或多个存储节点的控制接口，并执行控制节点进程的逻辑进程。逻辑过程包含存储节点的定义，哪些存储节点可以访问所需目标存储的映射，并根据请求将优先存储节点分配给客户机。每个存储节点都实现动态卷共享过程，可以替代现有的单片进程进程，并允许备份/恢复操作的可扩展性以及不同存储访问操作和不同类型的存储访问操作的并发执行。

摘要： Methods and systems are directed to a hybrid multi-thread/multi-process model to service a large number of network requests in network storage applications and systems. The process utilizes defined parameters of target session number, maximum session number, and maximum process number to determine an optimum load balance for read/write operations of a disk access session on a single storage node. This helps to achieve higher performance when using the single node to read or write a large number of separate and parallel data streams, and represents a marked improvement over current methods that multiplex the multiple data streams or use multiple I/O processes to write each data stream.
