摘要： A system for limiting fracturing of write data by a PCI bus adapter which queues operation commands in a command queue. The write data is in the form of bursts comprising a plurality of contiguous words. Fracture detection logic senses fracturing of the write data. A bus arbiter is responsive to the sensed fracturing of write data by the target, and blocks access to the PCI bus. Queue level detection logic is employed, subsequent to the blocking, to monitor completion of the queued operation commands of the PCI bus target. The bus arbiter is then responsive to the queue level detection logic indicating that the PCI bus target has completed enough operations that a predetermined number (such as one) of the operation commands remain queued at its command queue, and grants access to the PCI bus to complete the burst write operation without fracturing.

摘要： A method and system for controlling access to a bus for transferring data in the form of multibyte data streams. Data transfer agents are coupled to and request access to the bus to transfer data thereon. The system for controlling access to the bus comprises a bus arbiter responsive to the access requests of the data transfer agents, granting access to the bus to one data transfer agent at a time. A data length counter accumulates, during the grant of access, signals indicating the length of the data transferred between the bus and the data transfer agent. The data length counter indicates completion of the transfer of a predetermined length of data, and bus arbiter logic responds to the data length counter indicating the transfer completion, causing the bus arbiter to terminate the grant of access to the data transfer agent. The control of access to the bus is thus based on the precise measurement of the length of the transferred data, rather than on timers.
摘要翻译：一种用于控制访问总线以用于以多字节数据流的形式传送数据的方法和系统。数据传输代理被耦合到请求访问总线以在其上传送数据。用于控制对总线的访问的系统包括响应于数据传输代理的访问请求的总线仲裁器，一次授予对一个数据传输代理的总线访问。在授权访问期间，数据长度计数器累积指示在总线和数据传送代理之间传送的数据的长度的信号。数据长度计数器指示传输预定长度的数据的完成，并且总线仲裁器逻辑响应指示传送完成的数据长度计数器，导致总线仲裁器终止对数据传输代理的访问许可。因此，对总线访问的控制基于精确测量传输数据的长度，而不是基于定时器。

摘要： A PCI read access management system and method to manage read access between two agents providing PCI read requests to conduct contiguous read operations to a central resource at a PCI bus. Dual transaction control logic units are each respectively coupled to a separate one of the agents. An arbitration request connection couples the dual transaction control logic units. A PCI read request by one of the agents (e.g., agent A), and recognized by one of the dual transaction control logic units (e.g., unit 1), is signaled to the arbitration request connection, which arbitrates between the transaction control logic units for reserving the PCI bus for the one agent (agent A), and the one transaction control logic unit (unit 1) provides read access to the PCI bus for the one agent (agent A) for the contiguous read operations. The one transaction control logic unit (unit 1) then maintains the reservation until completion of the contiguous read operations.

摘要： An apparatus and method for copying data are disclosed. A data track to be replicated using a peer-to-peer remote copy (PPRC) operation is identified. The data track is encoded in a non-transitory computer readable medium disposed in a first data storage system. At a first time, a determination of whether the data track is stored in a data cache is made. At a second time, the data track is replicated to a non-transitory computer readable medium disposed in a second data storage system. The second time is later than the first time. If the data track was stored in the data cache at the first time, a cache manager is instructed to not demote the data track from the data cache. If the data track was not stored in the data cache at the first time, the cache manager is instructed that the data track may be demoted.
摘要翻译：公开了一种用于复制数据的装置和方法。识别要使用对等远程复制（PPRC）操作来复制的数据轨道。数据轨道被编码在布置在第一数据存储系统中的非暂时计算机可读介质中。在第一时间，确定数据轨迹是否存储在数据高速缓存中。在第二时间，将数据轨道复制到布置在第二数据存储系统中的非暂时性计算机可读介质。第二次比第一次晚。如果数据轨道首次存储在数据高速缓存中，则指示高速缓存管理器不从数据高速缓存降级数据轨道。如果数据轨道在第一时间未被存储在数据高速缓存中，则指示高速缓存管理器可以降低数据轨道。

摘要： Methods, controllers for data storage, data storage systems, and computer program products are directed to migrating data after the initial placement of the data in data storage entities having higher speed and in other data storage. Steps of a method to migrate data to the higher speed data storage are (1) identifying at least one group of data having had at least one I/O activity in each of a plurality of intervals of time, occurring over a string of multiple intervals of time, wherein the I/O activity is with respect to the other data storage from which data is to be migrated. The time for each of the multiple intervals is selected such that bursts of the I/O activity are likely to be contained in one interval. (2) The identified group of data is classified to the higher speed data storage and migrated.
