摘要： An apparatus for and method of implementing a cluster lock processing system having a relatively large number of commodity cluster instruction processors which are managed by a highly scalable, off the shelf communication processor. Because the commodity processors have virtually no system viability features such as memory protection, failure recovery, etc., the communication processor assumes the responsibility for providing these functions. The low cost of the commodity cluster instruction processors makes the system almost linearly scalable. Furthermore, having a fully scalable communication processor ensures a completely scalable system. The cluster/locking, caching, and mass storage accessing functions are fully integrated into a single hardware platform.

摘要： A system and method for processing I/O requests in a computing system. I/O packets are created via an operating system associated with the computing system, where the I/O packets include I/O transaction information. The I/O packets are made accessible to an I/O system. A command for a channel type connecting a target I/O component to the I/O system is constructed, where this command construction is based on the I/O transaction information provided in the I/O packet, and based on physical aspects of the target I/O component and channel type provided independently of the I/O packet. The constructed command is issued to the target I/O component in accordance with the channel type.

摘要： A system and method for testing I/O components without requiring initiation of the test I/O requests from the operating system via the instruction stream. An I/O system facilitates I/O operations between a processing system and I/O devices during normal I/O processing. An exerciser initiation queue is established, which corresponds to an operating initiation queue used during normal I/O processing. The I/O system is configured to monitor for test I/O requests on the exerciser initiation queue in lieu of monitoring for standard I/O requests on the operating initiation queue. A testing module enters the test I/O requests on the exerciser initiation queue in a format analogous to standard I/O requests entered on the operating initiation queue during normal I/O processing. The test I/O requests on the exerciser initiation queue are processed via the I/O system. Upon I/O completion, status may be returned to the testing module for processing of test results.

摘要： An apparatus for and method of enhancing reliability within a cluster lock processing system having a relatively large number of commodity cluster instruction processors which are managed by a cluster lock manager. Because the commodity processors have virtually no system viability features such as memory protection, failure recovery, etc., the cluster/lock processors assume the responsibility for providing these functions. The low cost of the commodity cluster instruction processors makes the system almost linearly scalable. The cluster/locking, caching, and mass storage accessing functions are fully integrated into a single hardware platform which performs the role of the master. Upon failure of this hardware platform, a second redundant hardware platform converts from slave to master role. The logic for the failure detection and role swapping is placed within software, which can run as an application under a commonly available operating system. Furthermore, the recovery is completely accomplished without assistance of the Host computer(s) or ultimate user(s) coupled via the Host computer(s).

摘要： A legacy operating system (OS) of a type generally associated with an enterprise-level, legacy data processing platform such as a mainframe is instead provided on a commodity data processing platform such as a personal computer. The legacy OS is adapted to communicate with legacy IOP devices of the type generally associated with the legacy platform to provide data protection mechanisms for legacy data. To initiate an I/O operation, a commodity OS executing on the commodity platform allocates a memory buffer and provides the virtual buffer address to the legacy OS. The legacy OS uses this address to construct a description of an I/O operation to be performed using the buffer. The description is then translated from one referencing a first memory page size in virtual address space into a description referencing a different page size in physical address space so that legacy IOP can complete the operation.
摘要翻译：通常与诸如大型机的企业级传统数据处理平台相关联的类型的传统操作系统（OS）被替代地提供在诸如个人计算机的商品数据处理平台上。遗留操作系统适于与通常与传统平台相关联的类型的传统IOP设备进行通信，以提供遗留数据的数据保护机制。为了启动I / O操作，在商品平台上执行的商品操作系统分配存储器缓冲器并且向传统OS提供虚拟缓冲器地址。传统操作系统使用该地址来构造要使用缓冲区执行的I / O操作的描述。然后，将描述从在虚拟地址空间中引用第一存储器页大小的描述转换为在物理地址空间中引用不同页大小的描述，使得传统IOP可以完成该操作。

摘要： The various embodiments of the invention relate to analyzing operations of an emulated input-output processor. Instructions native to the first type of instruction processor are emulated on a second-type instruction processor. The instruction processor emulator executes an operating system that includes instructions native to the first type of instruction processor. The operating system includes instructions that write input/output (IO) requests to the memory arrangement in response to IO functions invoked by a program. An IOP emulator that is executable on the second-type processor emulates IOP processing of IO requests from the memory arrangement. The IOP emulator maintains in the memory arrangement a first set of data structures used in processing the IO requests. State data currently contained in the data structures is stored on a retentive storage device, and in response to user input controls, the state data is read from retentive storage and displayed.

摘要： A method includes determining, by a processor, whether a program check condition exists. The method further includes determining, by the processor, whether a lock descriptor of a lock in a file lock table satisfies an unlocking condition. The method further includes releasing, by the processor, the lock by setting the lock descriptor's host identifier as zero. The method further includes determining, by the processor, whether any lock in the file lock table satisfies a lock conflict condition. The method further includes determining, by the processor, whether the file lock table includes any lock descriptor that satisfies a locking condition. The method further includes creating, by the processor, a new lock using the lock descriptor that satisfies the locking condition.
