Abstract: A computer-implemented method for host communication in a clustered file system may include 1) identifying a cluster file system site comprising at least one host that performs data operations on a storage unit, 2) identifying a storage management application that manages the storage unit, 3) transmitting, by an initial host, an initial data operation directed to a location of the storage unit, where the data operation comprises a notification signal that commands the notification of the initial host upon a subsequent host attempting to access the location, 4) transmitting, by the subsequent host, a subsequent data operation directed to the location of the storage unit, and 5) notifying the initial host, by the storage management application, that the subsequent host attempted to access the location of the storage unit. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A file storage system is implemented by coordinating non-exhaustible and exhaustible storage devices. The exhaustible storage devices include lower grade flash based storage devices. The non-exhaustible storage devices are based on magnetic recording mechanisms or higher grade flash storage. The file storage system stores received content items on the exhaustible storage devices, and stores metadata for the content items and/or the file storage system on the non-exhaustible storage devices. During operation, the file storage system globally optimizes the content items on the exhaustible storage devices such that more heavily accessed items are moved to exhaustible storage devices that have experienced relatively few data operations. The file storage system moves less frequently accessed content items to exhaustible storage devices that have experienced a relatively large number of data operations. As such, the operation lifetime of the exhaustible storage devices as a whole can be prolonged.

Abstract translation: 文件存储系统通过协调不可耗尽和可耗尽的存储设备来实现。 可耗尽的存储设备包括较低级别的闪存存储设备。 不可耗尽的存储设备基于磁记录机构或更高等级的闪存存储。 文件存储系统将可接收的内容项目存储在可耗尽的存储装置上，并将用于内容项目和/或文件存储系统的元数据存储在不可耗尽的存储装置上。 在操作期间，文件存储系统全局地优化可耗尽存储设备上的内容项目，使得更多访问的项目被移动到经历相对较少的数据操作的可耗尽的存储设备。 文件存储系统将经常访问的内容项目移动到经历了相对大量数据操作的可耗尽的存储设备。 因此，可以延长整个可消耗的存储装置的操作寿命。

Abstract: A method of managing read/write requests in a non-transitory data storage system includes receiving a read/write request for data stored in the data storage system and processing the read/write request on at least one computing processor. For a read request, the method includes computing a first checksum of the data, comparing the first checksum with a second checksum associated with the data, and allowing a read operation of the read/write request on the data when the first and second checksums match. For a write request, the method includes allowing a write operation of the read/write request on the data, computing a third checksum of the modified data, and associating the third checksum with the modified data.

Abstract: A manager program for managing virtual machines includes a process which receives a notification message indicating an occurrence of an event affecting a data storage unit in a data storage system that supports a shared file system. The notification message might have come from a virtual machine host or resulted from a hardware reconfiguration. The manager program then determines whether another virtual machine host is sharing the data storage unit. The manager program might make this determination by polling each of the virtual machine hosts it manages or by checking information previously collected and stored in a database. If another virtual machine host is sharing the data storage unit, the manager program sends a refresh message to that virtual machine host that causes the virtual machine host to update information relating to the data storage unit in a cache associated with the virtual machine host.

Abstract translation: 用于管理虚拟机的管理程序包括接收指示在支持共享文件系统的数据存储系统中影响数据存储单元的事件的发生的通知消息的处理。 通知消息可能来自虚拟机主机或由硬件重新配置导致。 管理程序然后确定另一个虚拟机主机是否共享数据存储单元。 管理程序可以通过轮询其管理的每个虚拟机主机或通过检查先前收集并存储在数据库中的信息来进行此确定。 如果另一个虚拟机主机正在共享数据存储单元，则管理程序向该虚拟机主机发送刷新消息，该虚拟机主机使虚拟机主机在与虚拟机主机相关联的高速缓存中更新与数据存储单元有关的信息。

Abstract: A server enforces a policy for selecting what received change to process. The non-selected changes are not processed by the server. Instead, after the selected change is processed and is incorporated into the current version of the text, the server sends an update to each of the clients indicating the change made to the current version of text. A client performs a conflict resolution procedure when its change was not processed by the server. The conflict resolution procedure detects the differences between the updated text version and its text change that was not accepted by the server and uses the differences to deduce the intent of the user and come up with a merged version of the text which preserves the intent and avoids data loss. The updated version is then sent back to the server to update the current version of the text.

Abstract translation: 服务器执行策略来选择要处理的接收到的更改。 未选择的更改不会被服务器处理。 相反，在所选择的更改被处理并被并入当前版本的文本之后，服务器向每个客户端发送指示对当前版本的文本所做的更改的更新。 当客户端的更改未被服务器处理时，客户端执行冲突解决过程。 冲突解决程序检测更新的文本版本与文本更改之间的差异，服务器不接受这些更改，并使用差异来推断用户的意图，并提出保留意图的文本的合并版本，并避免 数据丢失。 然后将更新的版本发送回服务器以更新当前版本的文本。

Abstract: One embodiment of the present invention provides a system that facilitates dividing financial data to facilitate simultaneous modifications by multiple users. During operation, the system receives division-criteria, which facilitates dividing financial-data into a first subset and a second subset. Next, the system creates a copy of the financial-data which includes the division-criteria. The system then allows a first user to modify the first subset of the financial-data. The system also sends the copy of the financial-data to a second user, thereby enabling the second user to modify the second subset of the financial-data in the copy of the financial-data to create a change file. Subsequently, the system receives the change file from the second user, wherein the change file comprises modifications to the financial-data. Finally, the system merges the change file into the financial-data.

Abstract: Optimistic concurrency is effectuated to manage constraints in a synchronization environment at multiple computing device endpoints in a consistent fashion without utilizing concentrated centralized constraint logic. Implemented data synchronization constraints that identify false violation scenarios may be automatically resolved without user intervention by using an etag system directed by a master component to assist computing device endpoints to maintain data synchronization among them. Data entries defining each file hierarchy component to be synched are generated and shared with the master component and each computing device endpoint in a synchronization environment. Individual computing device endpoints can use the data entries generated locally with those generated by other computing device endpoints to locally resolve identified false violation scenarios.

Abstract: An application makes a processor issue a first file access command to a middleware in order to access a file. In response to the first file access command, the middleware makes the processor periodically determine whether file access operation having a higher priority level than file access operation involved with the first file access command is being performed and, in the case where an affirmative determination is made, issue a second file access command corresponding to the first file access command within redundant bandwidth obtained by subtracting guaranteed bandwidth of the high-priority file access from the maximum bandwidth available for accessing the file storage.

Abstract: A client transmits, to a server, an instruction to copy a certain file for update, and receives the copied file. Upon update of the received file, the client generates update information on the update of the received file, and transmits the generated update information to the server. The server extracts a file containing a part related to the received update information, and judges whether or not the extracted file has been copied and then transmitted to a different client. If judging that the extracted file has been copied and transmitted to the different client, the server transmits warning information to the different client to which the extracted file has been transmitted, the warning information indicating that the file is updated in the client other than the different client.

Abstract translation: 客户端向服务器发送用于复制特定文件以进行更新的指令，并接收复制的文件。 在更新接收到的文件后，客户端生成关于接收文件的更新的更新信息，并将生成的更新信息发送到服务器。 服务器提取包含与接收到的更新信息相关的部分的文件，并且判断所提取的文件是否已被复制，然后发送给不同的客户机。 如果判断提取的文件已经被复制并发送给不同的客户端，服务器向发送提取的文件的不同的客户端发送警告信息，指示该文件在不同的客户端中被更新的警告信息 客户。
