摘要： A distributed data processing system includes a plurality of nodes interconnected by bidirectional communication links. Each node includes a control message line for handling of control messages and a control memory for storing the control messages. Each node further includes data message line for handling of data messages and a data memory for storing the data messages. A processor in the node causes the data message line to queue and dispatch data messages from the data memory and the control message line to queue and dispatch control messages from the control memory. Each node includes N bidirectional communication links enabling the node to have at least twice as much input/output bandwidth as the control message line and data message line, combined. An input/output switch includes a routing processor and is coupled between the N bidirectional communication links, the data message line and control message line. The input/output switch dispatches either a control message or a data message over at least one of the bidirectional communication links in accordance with an output from the routing control processor, thereby enabling each communication link to carry either data or control messages. If a communication link is busy with either a control or a data message, the routing control processor increments to another communication link to enable dispatch of a queued message.

摘要： A data storage system provides generalized record caching through a control unit adapted to support track caching in the upper level store of a two level memory. Dynamic reallocation of space between each type of caching in the upper store follows operating patterns of host computer systems using the data storage system. A storage controller cache has a plurality of segments. A directory data entry data structure is allocated each segment. Such allocated directory entries are used to identify tracks as cached. A plurality of unallocated directory entries are also provided. As a record is cached in a segment outside of a track slot, an unallocated directory entry is used to identify a virtual track in cache corresponding to the track of the record in the lower level store. Records from one track can thus appear in several segments outside track slots. Tracking of records to locate records least recently used is done globally over all track slots and record caching segments and locally within individual record caching segments. A mechanism is provided for identifying record slots, as they become least recently used, and dropping them from the upper level store in the face of competing demands for the space. A second mechanism identifies least recently used segments for dropping from the upper level store.
摘要翻译：数据存储系统通过适于支持两级存储器的上层存储器中的轨道缓存的控制单元提供广义记录高速缓存。在上层商店中的每种类型的缓存之间的动态重新分配空间遵循使用数据存储系统的主机系统的操作模式。存储控制器高速缓存具有多个段。每个段分配目录数据条目数据结构。这样分配的目录条目用于将轨道标识为缓存。还提供了多个未分配的目录条目。由于记录被缓存在轨道槽外的段中，所以使用未分配的目录条目来标识与低级存储中的记录的轨道相对应的高速缓存中的虚拟轨道。因此，来自一个轨道的记录可以出现在轨道槽外部的若干段中。跟踪记录以定位最近最少使用的记录是在所有轨道插槽上全局完成的，并记录缓存段，并在本地记录缓存段。提供了一种用于识别记录槽的机制，因为它们最近被使用，并且在面对空间的竞争性需求的情况下将其从高级存储中删除。第二种机制识别最近最少使用的段从高级存储中删除。

摘要： A first logical partition in a first processing complex of a server cluster is operated at a first level of a software code. Software code in a second logical partition in the same processing complex is changed to a second level. Processing operations are transferred from the first logical partition in the first processing complex to a third logical partition in a second processing complex of the server cluster. In another aspect, the transferring of processing operations includes quiescing the first logical partition to cause a failover of processing operations from the first logical partition in the first processing complex, to the third logical partition in the second processing complex. In yet another aspect, a failback operation is performed and a first portion of the processing operations are transferred from the third logical partition in the second processing complex, to the second logical partition in the first processing complex. In still another aspect, a second portion of the processing operations may be transferred from the third logical partition in the second processing complex, to the second logical partition in the first processing complex of the server cluster. In one example, the transferring of the second portion of processing operations includes quiescing the third logical partition to cause a failover of processing operations from the third logical partition in the second processing complex, to the second logical partition in the first processing complex. Other embodiments are described and claimed.

摘要： A method and system are disclosed for enhanced efficiency of backup copying of designated datasets stored within a plurality of storage devices coupled to the data processing system via a storage subsystem control unit having subsystem memory therein. Application execution within the data processing system is temporarily suspended long enough to form a dataset logical-to-physical system address concordance to be utilized to administer copying of the designated dataset. Thereafter, application initiated updates to uncopied portions of the designated datasets are temporarily deferred until sidefiles of the affected portions of the designated datasets are written to subsystem memory. The updates are then written to the storage subsystem. Portions of the designated datasets are then accessed and copied from the storage subsystem on a scheduled or opportunistic basis utilizing selected data retrieval command sequences. A sidefile status query is appended to selected data retrieval command sequences and the presence of data within the subsystem memory is determined without the necessity of additional communications between the data processing system and the storage subsystem. The sidefiles are then accessed and copied. Copied portions of the designated datasets and sidefiles are then copied to alternate storage locations in a backup copy order defined by the address concordance.
