摘要： In a fault-tolerant computer system, a primary replica supervisor is interposed between an operating system and a primary replica of an application program being executed by a primary processor. An object-code editor locates calls to the operating system and loops in the application program and inserts instruction sequences that enable the replica supervisor to intercept the calls to the operating system, results returned by the operating system as a result of the calls and asynchronous events delivered by the operating system to the replica. A backup replica supervisor is similarly interposed between an operating system and a backup replica of the application program being executed by a backup processor. The primary replica interacts with an environment. The replica supervisors ensure that the backup replica undergoes state transformations, as a result of the calls to the operating system and asynchronous events, that are equivalent to state transformations that the primary replica undergoes as a result of corresponding calls and asynchronous events. Thus, after a failure in the primary processor, the backup replica can interact with the environment in a manner consistent with interactions between the primary replica and the environment prior to the failure.
摘要翻译：在容错计算机系统中，主复制主管介于操作系统和由主处理器执行的应用程序的主副本之间。对象代码编辑器定位到操作系统的调用并在应用程序中循环，并插入指令序列，使得副本管理器能够拦截对操作系统的调用，由于调用和异步事件，操作系统返回的结果由操作系统交付给副本。备份副本管理程序类似地插入在由备份处理器执行的应用程序的操作系统和备份副本之间。主要副本与环境交互。由于对操作系统和异步事件的调用，副本监视器确保备份副本经历状态转换，这些转换等效于主副本作为相应调用和异步事件的结果进行的状态转换。因此，在主处理器发生故障之后，备份副本可以以与故障之前主要副本和环境之间的交互一致的方式与环境进行交互。

摘要： Transferring an application from a first site to a second site includes determining that the second site is a destination site for the application, causing writes by the application at the first site to be propagated semi-synchronously to the second site, transferring storage data from the first site to the second site, suspending operation of the application on the first site, and resuming operation of the application on the second site. The application may be a virtual machine or a host cluster capable of transitioning applications between cluster nodes. The virtual machine may be transferred from the first site to the second site by transferring an image of the virtual machine from the first site to the second site. The destination site may be selected by a user. The second site may be located remotely from the first site across an asynchronous distance.

摘要： Dynamic mobility of virtual data centers and converged infrastructure components, such as Vblocks, may be provided using a virtual platform product that federates and/or coordinates virtual storage. The system described herein enables sharing of distributed resources between multi-connected virtual platform clusters, such as VPLEX clusters, in a dynamic sharing arrangement. A virtual platform cluster may include one or more pairs of directors that enables failover from one director of the pair(s) to the other director of the pair(s) in a cluster in the case of hardware or path failure.

摘要： Technology for minimizing disruptions when host data on a physical volume is encapsulated into a virtualization layer or de-encapsulated is disclosed. Evaluation of a physical volume used as data storage for a virtualization layer before committing to direct access to the physical volume is enabled by preventing direct access before presenting the physical volume directly to the host and by preventing the virtualization layer from moving data on the physical volume while redirecting to the physical volume a first plurality of I/O requests that were directed to the virtualization layer.
