摘要： Each node in a clustered array is the owner of a set of zero logical disks (LDs). Thinly-provisioned VVs (TPVVs) are partitioned so each is mapped to a group of zero LDs from different sets of zero LDs. When there is a change in ownership, the affected zero LDs are switched one at a time so only a group of the TPVVs is affected each time.

摘要： An apparatus and protocol to determine the group of processors that will survive communications faults and/or timed-event failures in a multiprocessor system. The processors each have a respective memory, and the processors are coupled by means of an inter-processor communication network. The processors detect that the set of processors with which they can communicate has changed. They can choose to either halt or continue operations based on minimizing the likelihood that disconnected groups of processors will continue to operate as independent systems. The processors construct a connectivity matrix on the initiation of a regroup operation. The connectivity information is used to ensure that all the processors in the final group that survives can communicate with all other processors in the group. One or more processors may halt to achieve this characteristic. A processor is suspected of having ceased operations or having a failed timer mechanism when other processors detect the absence of a periodic message from the processor. When this happens, all of the processors are subjected to a series of stages in which they repeatedly broadcast their status and connectivity to each other. The suspected processor does not advance through the stages if it has ceased operations or if its timer mechanism has failed.

摘要： A data processing system for transferring data is provided. This system includes central processing units (CPUs 20, 22, 24 and 26) and storage units (30 and 32 with 100-105 and 110-115) which are interconnected by a network (10). The CPUs (20, 22, 24 and 26) include a request process (133) and a storage process (130). The storage process (130) controls access to the storage unit (30 with 100-105 and 110-115). Software routines (220) are used to provide direct access to the storage unit (30 with 100-105 and 110-115) by the request CPU (22). The request CPU (20) is the CPU containing the request process (133). A virtual memory address for a buffer (160) of the request CPU (22) is created in the request CPU (22). The virtual memory address along with a storage unit access request are sent to the CPU (20) containing the storage process (130). A work request including the virtual memory address to sent from the storage process (130) to the storage unit (30 with 100-105 and 110-115). The data is then transferred directly between the request CPU (22) and the storage unit (30 with 100-105 and 110-115). The storage unit (30 with 100-105 and 110-115) then responds to the work request.

摘要： A multiprocessor that includes a virtual file system providing a file system interface to user application code. This interface allows users to access files in many types of file systems in a consistent, file system-independent manner. In a preferred embodiment, the higher interface of the file system is the Posix file system interface, though it can be any file system interface supporting the capabilities required by a user process. The Posix file system supports regular files, pipes, fifos and special files.A pipe server, a pipe library and a name server together implement the fifo semantics required by the Posix standard for Posix processes. The present invention provides these fifo capabilities to any process which uses the Posix interfaces.

摘要： A method and apparatus for detecting and tolerating situations in which one or more processors in a multi-processor system cannot participate in timer-driven or timer-triggered protocols or event sequences. The multi-processor system includes multiple processors each having a respective memory. These processors are coupled by an inter-processor communication network (preferably consisting of redundant paths).Processors are suspected of having failed (ceased operations) outright or having a failed timer mechanism when other processors detect the absence of periodic "IamAlive" messages from other processors. When this happens, all of the processors in the system are subjected to a series of stages in which they repeatedly broadcast their status and their connectivity to each other. During the first such stage, according to the present invention, a processor will not assert its ability to participate unless its timer mechanism is working. It arms a timer expiration event and does not assert its health until and unless that timer expiration event occurs.
摘要翻译：一种用于检测和容忍多处理器系统中的一个或多个处理器不能参与定时器驱动或定时器触发的协议或事件序列的情况的方法和装置。多处理器系统包括多个具有相应存储器的处理器。这些处理器通过处理器间通信网络（优选地由冗余路径组成）耦合。当其他处理器检测到不存在来自其他处理器的周期性“IamAlive”消息时，处理器被怀疑已经失败（停止操作）或定时器机制失败。当这种情况发生时，系统中的所有处理器都经历一系列阶段，在这些阶段中，它们重复地广播其状态及其彼此的连接。在第一个这样的阶段期间，根据本发明，处理器将不会断言其参与的能力，除非其定时器机制正在工作。它会阻止定时器到期事件，并且除非发生定时器到期事件，否则不会断言其状态。
