摘要： A technique for performing synchronous replication on both block and file-based objects provides a data storage system that internally stores data objects (e.g., LUNs, file systems, block-based vVOLs (virtual volumes), file-based vVOLs, VMDKs, etc.) in the form of respective files, such that each file provides a realization of a data object. The data storage system maps each such file to a respective logical volume, and each logical volume provides a block-based interface. As the data storage system receives IO requests specifying data to be written to a data object, the data storage system renders the IO requests as block-based requests, regardless of whether the IO requests are themselves block-based or file-based. A block-based replication splitter intercepts the block-based requests directed to the logical volumes and performs block-based, synchronous replication on the requests, thereby achieving synchronous replication of both block-based objects and file-based objects in a single, unified architecture.
摘要翻译：在基于块和文件的对象上执行同步复制的技术提供了一种在内部存储数据对象（例如，LUN，文件系统，基于块的vVOL（虚拟卷），基于文件的vVOL，VMDK等）的数据存储系统。），使得每个文件提供数据对象的实现。数据存储系统将每个这样的文件映射到相应的逻辑卷，并且每个逻辑卷提供基于块的接口。当数据存储系统接收指定要写入数据对象的数据的IO请求时，数据存储系统将IO请求呈现为基于块的请求，而不管IO请求本身是基于块还是基于文件。基于块的复制分配器拦截针对逻辑卷的基于块的请求，并对请求执行基于块的同步复制，从而实现基于块的对象和基于文件的对象在单一统一架构中的同步复制。

摘要： A power delivery technique which involves connecting power sourcing equipment (PSE) with a powered device (PD) through data communications cabling (e.g., an Ethernet cable). The technique further involves negotiating an acceptable power level for the PD and a data rate for the PD, and enforcing delivery of power to the PD using only wire pairs of the data communications cabling which carry data between the PSE and the PD. As a result, the PSE does not deliver any power to the PD through wire pairs which are not data-active.

摘要： Techniques are presented for implementing non-host-based migration in a manner that is not subject to certain types of data corruption. This may be accomplished by preventing any hosts from having write access to a target LUN until it can be confirmed that all applications that access a source LUN have been shut down. This arrangement prevents accidentally writing to the target LUN while the source LUN is still being accessed. As a further precaution, just in case the confirmations are incorrect, a target data storage system can direct a source data storage system to remove access to the source LUN from all of the hosts, which has a similar effect. The migration can then proceed.

摘要： A magnet arrangement includes (a) a first and a second head ring magnet each having a substantially circular geometry with respect to a center axis and (b) a central ring magnet having a substantially circular geometry with respect to a center axis. The central ring magnet is disposed between the first and second head ring magnet in direction of the center axis. At least one of the magnets includes a first number of first magnets having at least one trapezoidal cross section and a second number of second magnets having at least one rectangular cross section. The second magnets are disposed in between the first magnets in circumferential direction. With this geometrical arrangement, magnets having a trapezoidal cross section include a guidance for a magnet having a rectangular cross section allowing the movements in radial direction of these last magnets.

摘要： Examples are generally directed towards disabling features using a feature toggle associated with an application programming interface (API). A server receives an API request including one or more elements. An element is associated with a set of features. If a feature state of every feature within the set of features is an enabled feature state, the element state is an enabled element state and the request is validated. The validated request is executed and a response to the request is returned to the client. If at least one feature state of at least one feature within the set of features is a disabled feature state or a hidden feature state, the element state is a disabled element state and the request is invalided. The invalidated request is rejected and an error message is returned to the client.

摘要： Described herein are methods and systems for selectively synchronizing locally stored data with data stored in a cloud storage repository. A client application can synchronize a portion of the locally or remotely stored content by choosing to synchronize data that is frequently used, data that is marked as priority data or data that was modified or otherwise accessed during a predetermined period of time. Other selective synchronization optimizations include predictively synchronizing data or content associated with frequently use or priority data and synchronizing data according to a priority score.

摘要： A method is provided of generating and distributing secret random data. The method requires a plurality of participating parties each to own an identical private-key generation device and to request a random signal over a shared publication communication network. At each iteration of the method, the parties process the public random signal with the internal states of their secret-key generation devices using two functions, the output of the first function being generated secret random data and the output of the second function being a new internal state.

摘要： A fluid analyzer includes an optical source and detector defining a beam path of an optical beam, and a fluid flow cell on the beam path defining an interrogation region in a fluid channel in which the optical beam interacts with fluids. One or more flow-control devices conduct a particle in a fluid through the fluid channel. A motion system moves the interrogation region relative to the fluid channel in response to a motion signal, and a controller (1) generates the motion signal having a time-varying characteristic, (2) samples an output signal from the optical detector at respective intervals of the motion signal during which the interrogation region contains and does not contain the particle, and (3) determines from output signal samples a measurement value indicative of an optically measured characteristic of the particle.
