摘要： A system and method provides a single system image for a clustered storage network including techniques for processing data access commands between storage appliances over the cluster interconnect. The system is configured such that the cluster is assigned a single world wide nodename. Requests coming to the cluster from client initiators are directed to one or the storage appliances in the cluster, i.e. the “receiving” storage appliance. Commands received by the receiving storage appliance are examined to determine LUN value(s) in the request. If the LUN value is associated with a local storage device, the request is processed by the receiving storage appliance. If the LUN value is not associated with the receiving storage appliance, the request is conveyed over the cluster interconnect to the partner storage appliance to be processed and the appropriate data written or retrieved.

摘要： This invention provides a system and method for selecting and communicating a single disk (a “coredump disk”) for use in a coredump procedure by a failed file server (or filer). A selection method on the failed filer determines the “best candidate” coredump disk according to a predetermined set of criteria. For example, the available disks that can receive coredump data are located and ordered so as to prefer disks that best match the coredump data size requirement, are least likely to be needed for normal service by the server; and require the least preparation to receive coredump data. Appropriate attributes on the selected coredump disk are written to indicate that a coredump is in progress, and the location of the coredump data. Upon reboot of the failed filer (or takeover by a cluster partner), the coredump disk is identified and the coredump data recovered by reading back appropriate attributes.
摘要翻译：本发明提供了一种用于选择和通信由故障文件服务器（或文件管理器）在核心转储器过程中使用的单个盘（“核心转储盘”）的系统和方法。故障文件管理器上的选择方法根据预定的一组标准确定“最佳候选”核心转储盘。例如，可以接收coredump数据的可用磁盘是定位和排序的，以便更好地匹配coredump数据大小要求的磁盘，服务器的正常服务最不可能需要; 并要求最少的准备接收coredump数据。写入所选coredump磁盘上的适当属性，以指示coredump正在进行，以及coredump数据的位置。在重新启动失败的文件管理器（或由群集合作伙伴接管）时，将通过读取适当的属性来识别核心转储磁盘并恢复核心转储器数据。

摘要： A system and method for allowing more rapid takeover of a failed filer by a clustered takeover partner filer in the presence of a coredump procedure (e.g. a transfer of the failed filer's working memory) is provided. To save time, the coredump is allowed to occur contemporaneously with the takeover of the failed filer's regular, active file service disks by the partner so that the takeover need not await completion of the coredump to begin. This is accomplished, briefly stated, by the following techniques. The coredump is written to a single disk that is not involved in regular file service, so that takeover of regular file services can proceed without interference from coredump. A reliable means for both filers in a cluster to identify the coredump disk is provided, which removes takeover dependence upon unreliable communications mechanisms. A means is provided for identification during takeover of the coredump disk and SCSI-3 reservations are employed to coordinate write access to (ownership of) shared disks, so as to prevent takeover from interfering with coredump while simultaneously preventing the failed filer is from continuing to write regular file system disks being taken over by its partner.
摘要翻译：提供了一种用于在存在核心转储程序（例如，失败的文件管理器的工作存储器的传送）的情况下允许由集群接管合作伙伴文件管理器更快地接管失败的归档器的系统和方法。为了节省时间，核心转储器被允许与合作伙伴接管失败的文件管理器常规的活动文件服务磁盘同时发生，以便接管无需等待核心转储完成。这通过以下技术简要说明了。 coredump写入不涉及常规文件服务的单个磁盘，因此可以在不受coredump干扰的情况下继续执行常规文件服务。提供了集群中的两个文件管理器来识别核心转储磁盘的可靠方法，这消除了对不可靠的通信机制的接管依赖。提供了一种用于在核心转储盘接管期间进行识别的手段，并且采用SCSI-3保留来协调对共享磁盘的（所有权）的写访问，以防止接管干扰核心转储，同时防止失败的文件管理器继续编写由其合作伙伴接管的常规文件系统磁盘。

摘要： A system and method for reclaiming unused space from a thinly provisioned data container served by a storage system. A host-side agent detects blocks of the data container that may be freed and sends a novel Punch Hole command to the storage system associated with the data container. The storage system allocates the appropriate blocks in response to the Punch Hole command.

摘要： Various computing components (such as devices, operating environments, and processes) may communicate by exchanging instances of a data collection, such as a class or data structure. However, the definition of the data collection may evolve to specify different numbers, types, properties, and orderings of the items in the data collection, and it may be difficult to verify the structure and contents of an instance received from another component and possibly of a different version. This difficulty may be mitigated by exchanging versioning information about the instance (e.g., as part of the communications wire protocol) and by allocating the converting such that the sender may downconvert to earlier versions requested by a recipient, while the recipient may upconvert to later versions than a version provided by a sender. These techniques may promote the accuracy and consistency of information exchange among many components that operate on different versions of the data collection.
摘要翻译：各种计算组件（例如设备，操作环境和过程）可以通过交换诸如类或数据结构之类的数据收集的实例进行通信。然而，数据收集的定义可能演变为指定数据收集中项目的不同数量，类型，属性和顺序，并且可能难以验证从另一个组件接收的实例的结构和内容，一个不同的版本。通过交换关于实例的版本信息（例如，作为通信线路协议的一部分），并通过分配转换使得发送者可以下变频到由接收者请求的早期版本，而接收者可以升级到更高版本，来减轻这个困难而不是由发件人提供的版本。这些技术可以促进在不同版本的数据收集中运行的许多组件之间的信息交换的准确性和一致性。
