摘要： A laser transmitter includes an input stage generating an input signal to a limiting amplifier, the limiting amplifier generating an input signal to a laser driver, and the laser driver generating an input signal to a light source. The limiting amplifier has a control terminal for receiving a control signal that sets an amplitude characteristic of the input signal to the laser driver. The amplitude characteristic may be a common-mode or a peak amplitude of the input signal to the laser driver.

摘要： A method and apparatus for ensuring valid journaled file system metadata during a backup operation are provided. With the method and apparatus, mechanisms are provided for suspending write I/O operations to storage devices during a point-in-time backup operation. Once the point-in-time backup operation is completed, the suspended write I/O operations are released and may then be processed by the storage system. In one exemplary embodiment, when a point-in-time operation is initiated, a point-in-time backup flag is set in a logical volume manager. In response to receiving a write I/O operation, the logical volume manager checks the status of the point-in-time backup flag to determine if a point-in-time backup operation is currently being performed. If the flag is not set, then the write I/O operation is logged and performed in a normal manner. If the flag is set, then the write I/O operation is stored in a hold queue of the logical volume manager. The write I/O is not permitted to be sent to the storage system while stored in the hold queue. When the point-in-time backup operation is completed, the suspended write I/O operations in the hold queue are permitted to be sent to the storage system and the metadata for the file system is updated to reflect the committing of the write I/O operations.
摘要翻译：提供了一种用于在备份操作期间确保有效的日志文件系统元数据的方法和装置。通过该方法和装置，提供了用于在时间点备份操作期间将写入I / O操作暂停到存储设备的机制。一旦时间点备份操作完成，暂停的写入I / O操作将被释放，然后由存储系统进行处理。在一个示例性实施例中，当启动时间点操作时，在逻辑卷管理器中设置时间点备份标志。响应于接收到写入I / O操作，逻辑卷管理器检查时间点备份标志的状态，以确定当前正在执行时间点备份操作。如果标志未设置，则写入I / O操作将以正常方式记录并执行。如果标志被设置，则写入I / O操作被存储在逻辑卷管理器的保持队列中。存储在保留队列中时，不允许将写入I / O发送到存储系统。当时间点备份操作完成时，允许在保留队列中暂停的写入I / O操作被发送到存储系统，并且文件系统的元数据被更新以反映写入I / O操作。

摘要： A cluster server manages allocation of free blocks to cluster clients performing writes in a clustered file system. The cluster server manages free block allocation with a free block map and an in-flight block map. The free block map is a data structure or hardware structure with data that indicates blocks or extents of the clustered file system that can be allocated to a client for the client to write data. The in-flight block map is a data structure or hardware structure with data that indicates blocks that have been allocated to clients, but remain in-flight. A block remains in-flight until the clustered file system metadata has been updated to reflect a write performed to that block by a client. After a consistency snapshot of the metadata is published to the storage resources, the data at the block will be visible to other nodes of the cluster.

摘要： After a clone file is created from a file, a write request targeting the clone file can be handled. It is determined that the write request indicates the clone file that was cloned from a file in a first fileset. The clone file is of a second fileset and a clustered file system comprises the first fileset and the second fileset. A data block of the clone file affected by the write request is determined. It is then determined that the data block at a current location cannot be modified. The write request is implemented with respect to the data block at a different location. It is indicated that the data block at the different location can be modified for subsequent write requests that indicate the clone file.

摘要： A method includes initiating committing to persistent storage of a current consistency snapshot of a plurality of data objects in a redirect-on-write file system. Each of the plurality of data objects has a first copy of at least two copies of the data having a first context of at least two contexts. The method includes receiving, during committing to storage of the current consistency snapshot, an update to a data object of the plurality of data objects. The method also includes responsive to receipt of the update to the data object, creating a second copy of data of the data object from the first copy. The second copy of the data has a second context of the at least two contexts. The method includes responsive to receipt of the update to the data object, updating, based on the update, the second copy of the data of the data object.

摘要： One embodiment is for using a sparse file as a clone. The method includes creating, by an application associated with a computer system, a snapshot of a file, such as an individual file, a collection of files, file system, directories, and so forth. Further, the method includes requesting, by the application, a clone of that created snapshot. Further still, the method includes generating, by the application, an empty sparse having at least one inode identifying the empty sparse file as the clone and pointing to the snapshot associated with the clone. Thereby, the requested clone is created using the created sparse file, which begins as an empty sparse file.

摘要： A communication system includes a hybrid signal transmitter incorporating a signal routing circuit and a driver circuit. The signal routing circuit is configured to receive a first input signal and route the first input signal through a first signal path when the frequency bandwidth of the input signal is lower than a threshold frequency and through a second signal path when the frequency bandwidth exceeds the threshold frequency. The second signal path includes a frequency down-converter circuit. The driver circuit is configured to receive the routed input signal via the first signal path or the second signal path, and convert the routed input signal into an optical signal for coupling into an optical fiber.
