摘要： An apparatus, system, and method are provided for isolating a storage application from a network interface driver. The apparatus includes a definition module, an application interface, a translation module, and a data buffer. The definition module defines a set of storage application functions. The translation module translates each storage application function to one or more network interface driver functions. The data buffer transfers data blocks between the storage application and the network interface driver.

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 controller (104) for a storage system (100) in which there are multiple storage devices (109) and a method for recording diagnostic information are provided. The storage controller (104) includes a storage device manager (203) which has means for allocating a storage device (109) in the storage system (100) for storing diagnostic data. The storage controller (104) also includes means for generating diagnostic data regarding the operation of the storage controller (104). Two buffers (207, 208) are used for alternately recording and writing batches of diagnostic data to the allocated storage device (109). The allocated storage device may be a storage device which is normally reserved for disaster recovery in the storage system (100).

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.
