摘要： Provided are a method, system, and article of manufacture for managing write requests in cache directed to different storage groups. A determination is made of a high and low thresholds for a plurality of storage groups configured in a storage, wherein the high and low thresholds for one storage group indicate a high and low percentage of a cache that may be used to store write requests to the storage group. A determination is made of a number of tasks to assign to the storage groups based on the determined high and low thresholds for the storage groups, wherein each task assigned to one storage group destages write requests from the cache to the storage group.

摘要： In a data storage system having a direct access storage device (DASD) and a cache, a cache directory has two types of directory entries. A track directory entry TDE identifies up to one DASD track of data records currently stored in cache. All records stored in a DASD track can be stored in a cache storage space allocated for the DASD track identified by the TDE. A cylinder directory entry CDE identifies a number N of records from any track in a respective cylinder of tracks. N is a positive integer less than the total number of records storable in a DASD track. From one to all of the DASD tracks in one cylinder may be identified in a CDE. The cache data storage allocation corresponding to a CDE is the same as that allocated for a TDE. Each TDE is addressed by a DASD track address of a cylinder while a CDE is addressed using a pseudo track number corresponding to a servo track in the DASD. A record cast out control for the cache includes examining the number of records destaged. Based on the number of records cast out from cache to DASD, a cache event parameter CEP is modified or maintained. Accessing cache requires examining a current CEP value for each accessed DASD track to access either the TDE or CDE.
摘要翻译：在具有直接访问存储设备（DASD）和高速缓存的数据存储系统中，高速缓存目录具有两种类型的目录条目。轨道目录条目TDE最多识别当前存储在高速缓存中的数据记录的一个DASD轨道。存储在DASD轨道中的所有记录可以存储在由TDE标识的DASD轨道分配的高速缓存存储空间中。圆柱体目录条目CDE从轨道的相应圆柱体中的任何轨道识别N个记录。 N是小于在DASD轨道中可存储的记录总数的正整数。在一个气缸中的一个到所有DASD轨迹可以在CDE中被识别。与CDE对应的缓存数据存储分配与分配给TDE的缓存数据存储分配相同。每个TDE由气缸的DASD轨道地址寻址，而使用对应于DASD中的伺服轨道的伪轨道号来寻址CDE。高速缓存的记录丢弃控制包括检查已删除的记录数。根据从缓存转发到DASD的记录数，缓存事件参数CEP被修改或维护。访问缓存需要检查每个访问的DASD磁道的当前CEP值以访问TDE或CDE。

摘要： A method and system for enhancing the efficiency of communication between one or more host computers and a storage system controller during a data search within either the associated storage systems or within the storage system controller itself. A storage system controller, coupled to one or more host computers via multiple communication channels, is utilized to control access to one or more direct access storage devices. A host computer authorizes the storage system controller to search within a range of data locations within the storage system, sets an initial location from which the data search will begin, and specifies a key field argument to search for. The host computer then permits the storage system controller to independently search the authorized range of data locations within the storage system or within cache memory within the storage system controller. The storage system controller examines multiple records within the authorized range of data locations to locate a desired record associated with the key field argument and presents a status report to the host computer only after the desired record is located or the entire range of data is searched and the desired record was not located. Allowing the storage system controller to independently search records and report status only after completion of an attempt to find a desired record within an authorized range of records minimizes communication overhead. Reducing the number of status reports presented over the communication channel enhances communication efficiency.
摘要翻译：一种用于在关联的存储系统内或存储系统控制器本身内的数据搜索期间增强一个或多个主计算机与存储系统控制器之间的通信效率的方法和系统。利用经由多个通信信道耦合到一个或多个主计算机的存储系统控制器来控制对一个或多个直接存取存储设备的访问。主计算机授权存储系统控制器在存储系统内的数据位置范围内搜索，设置数据搜索开始的初始位置，并指定要搜索的关键字段参数。然后，主计算机允许存储系统控制器独立地搜索存储系统内的数据位置的授权范围或存储系统控制器内的高速缓冲存储器内。存储系统控制器检查数据位置的授权范围内的多个记录，以定位与密钥字段参数相关联的期望记录，并且仅在找到所需记录或搜索整个数据范围之后才向主计算机呈现状态报告，没有找到所需的记录。只有在完成尝试在授权的记录范围内找到所需记录之后，才允许存储系统控制器独立地搜索记录和报告状态，从而最大限度地减少通信开销。通过通信渠道减少状态报告的数量增加了通信效率。

摘要： The invention teaches a system and method for temporarily buffering data written to a storage system by a host computer. The storage system includes direct access storage devices and a cache. The cache is used as the buffer for both caching and noncaching data records before destaging to a direct access storage device. Upon receipt of a channel program from a host computer containing data for records to be updated, the storage controller determines if the records are currently cached. If the records are not cached, a write miss has occurred. Upon a write miss the storage controller checks an attribute transmitted in the channel program to determine if the records have a regular format. Records having a known, regular format are buffered in cache until destaged by a background process.
摘要翻译：本发明教导了一种用于临时缓冲由主计算机写入存储系统的数据的系统和方法。存储系统包括直接访问存储设备和缓存。缓存用作缓存和非缓存数据记录的缓冲区，然后再次转到直接访问存储设备。在从包含要更新的记录的数据的主计算机接收到频道节目时，存储控制器确定记录是否被当前缓存。如果记录未缓存，则发生写入错误。在写入错误时，存储控制器检查在通道程序中发送的属性，以确定记录是否具有常规格式。具有已知的常规格式的记录被缓存在缓存中，直到由后台进程去运行。

摘要： Provided are a method, system and program for using multiple data structures to manage data in cache. A plurality of data structures each have entries identifying data from a first computer readable medium added to a second computer readable medium. A request is received for data in the first computer readable medium. A determination is made as to whether there is an entry for the requested data in one of the data structures. The requested data is retrieved from the first computer readable medium to store in the second computer readable medium in response to determining that there is no entry for the requested data in one of the data structures. One of the data structures is selected in response to determining that there is no entry for the requested data in one of the data structures and an entry for the retrieved data is added to the selected data structure.

摘要： Disclosed is a system for caching data. After determining a sequential access of a first memory area, such as a direct access storage device (DASD), a processing unit stages a group of data sets from the first memory area to a second memory, such as cache. The processing unit processes a data access request (DAR) for data sets in the first memory area that are included in the sequential access and reads the requested data sets from the second memory area. The processing unit determines trigger data set from a plurality of trigger data sets based on a trigger data set criteria. The processing unit then stages a next group of data sets from the first memory area to the second memory area in response to reading the determined trigger data set.
