摘要： A method and apparatus for managing a loop network, the loop network (200) including at least one loop (206, 208), a plurality of devices (210) connected to the at least one loop (206, 208) via ports (211, 212), wherein at least two of the devices are initiators (207, 209). The method includes each initiator (207, 209) sending a frame to all other initiators (207, 209) in the loop network (200) identifying any ports (211, 212) which should not be used. Each initiator (207, 209) merges the information from all other initiators (207, 209) with its own information identifying any ports (211, 212) which should not be used resulting in all the initiators (207, 209) generating a single list of ports (211, 212) to be used which is consistent across all the initiators (207, 209). Each initiator (207, 209) applies an algorithm (300) to determine a common set of ports (211, 212) to be used by all the initiators (207, 209) and to balance port accesses across the loop network (200).
摘要翻译：一种用于管理环路网络的方法和装置，所述环路网络（200）包括至少一个环路（206,208），经由端口（211）连接到所述至少一个环路（206,208）的多个设备（210），212），其中所述装置中的至少两个是引发器（207,209）。该方法包括向循环网络（200）中的所有其他启动器（207,209）发送帧的每个发起者（207,209），其识别不应使用的任何端口（211,212）。每个启动器（207,209）将来自所有其他发起者（207,209）的信息与其自己的信息合并，以识别不应使用的任何端口（211,212），导致生成单个列表的所有发起者（207,209）的端口（211,212），其在所有启动器（207,209）中是一致的。每个启动器（207,209）应用算法（300）来确定要由所有发起者（207,209）使用的公共端口集合（211,212），并平衡跨越环路网络（200）的端口访问。

摘要： An apparatus operable with a host and at least first and second data storage for avoiding overwriting of a stored data item in the second data storage by a copy services system is provided. The apparatus includes a storage use analyzer for determining the availability of the second data storage. A copy services requester communicates with the host to receive a request to establish a copy services relationship, using the second data storage as a target data storage. A request blocking and passing component passes the request to establish a copy services relationship using the second data storage as the target data storage, responsive to a positive determination of availability of the second storage. The request blocking and passing component may also block the request responsive to a negative determination of availability of the second data storage.

摘要： A host data processing system includes a data storage system having a cache memory and a back end storage. In response to a detection of an event failure during an input/output (I/O) request from the host data processing system to the data storage system, the data associated with the I/O request is forwarded to the back end storage data, and a copy of the data associated with the I/O request is sent to the cache memory. A determination is made as to whether or not there is an acknowledgement from the back end storage regarding the receipt of the data associated with the I/O request. If there is an acknowledgement from the back end storage regarding the receipt of the data associated with the I/O request, the data associated with the I/O request is flushed from the cache memory, and the received acknowledgement is routed to the host data processing system.

摘要： An apparatus for data transmission over a network includes a buffer and a timer mechanism for timing an optimum interval (less than the round-trip error response delay) for retransmission of data. A first accessor accesses data in the buffer for transmission and starts a first timeout clock. Second or further accessors of the buffer are responsive to a timeout to access the data, start a timeout clock and attempt to transmit the data on a path avoiding path elements used by prior accessors. A counter increments and decrements a count of the references to the buffer by accessors and signals when the count reaches zero. A memory manager returns the buffer to a free buffer pool responsive to the reference counter signaling that the count has reached zero. An analysis mechanism can be used to determine the optimum interval and tune the timer mechanism.

摘要： A storage network control apparatus is operable to present virtualized storage to a host system and includes a monitoring component, an analysis component, a detection component, and a migration component. The monitoring component is for monitoring input/output (I/O) activity for virtual storage logical units over time. The analysis component is for identifying a repeating instance of peak I/O activity for a virtual storage logical unit over time and for generating a predictive signature therefrom. The detecting component is for identifying an instance of such a predictive signature. The migration component is responsive to the detecting component, and is for migrating data mapped by the virtual storage logical unit across additional real storage units to improve the I/O performance of the virtual storage logical unit prior to a recurrence of the repeating instance of peak I/O activity. A corresponding logic arrangement may be incorporated in hardware, software or a combination thereof.
