摘要： A method and apparatus for enabling a magnetic disk storage device that stores data according to a first data structure characterized by a fixed-length disk block size to respond to input/output requests from a host that define data according to a different data structure characterized by a different fixed-length host block size. A host adapter transfers requests and data between the host and a cache memory in the magnetic disk storage device as host blocks. A disk adapter transfers requests and data between the cache memory and magnetic disks as disk blocks. CRC data and a sector number are appended to each host block in a set of disk blocks.

摘要： A method and apparatus for verifying the organization of a magnetic disk storage system in which individual storage logical volumes are grouped in sequence as components of a meta device. Data concerning the organization of the meta device is stored in each storage logical volume in a dedicated storage area and in a global memory accessible to the data processing system. Whenever the integrity of the meta device is tested, the data in the configuration file and the data in the dedicated storage area are analyzed and compared. If identity exists, integrity is assumed. If identity does not exist various errors are generated to prevent use of the storage logical volume until the problem is resolved.

摘要： A mass storage system has a host computer connecting over a standard bus to a storage controller. The storage controller connects also to an array of disk drives. The host computer and the storage controller modify standard bus diagnostic commands for transmitting selected, non-diagnostic commands, and responses to each other. In this manner, a standard bus protocol is expanded to enable a host computer and storage controller to communicate, for example, configuration data, status, and some command information, particularly enabling the user at the host computer to control operational aspects of the storage controller.

摘要： Disk array storage device apparatus for enhancing the performance of an application on a data processing system that operates with a disk array storage device in which the completion of tasks associated with different transactions with one logical storage device are conditions precedent to the completion of other transactions. Specific tasks related to the one logical device are given priority over tasks related to all other logical storage devices. In a specific implementation reconnect tasks are given the highest priority with reconnect tasks from the one logical storage device being given the highest priority. A second category of tasks related to the one logical storage device can be given priority over all other tasks except reconnect tasks. All other tasks are given a priority below that of the first and second task categories.

摘要： An apparatus and method for retrieving a data file from a disk drive storage which provide for overlapping read operations thereby reducing the latency seen by a requesting host computer. The host computer requests the retrieval of a data file and a channel director places that request in a data cache. If the data file is not in the data cache, a disk director reads and transfers the data file from the disk drive to the data cache. At a certain point in the transfer of the data file into the data cache, the disk director places a start read message in the data cache which is then read by the channel director. Upon receipt of the start read message, the channel director begins to read the data file from the data cache, thus reading data from the data cache as the disk director completes writing the data file to the data cache. The channel director can adaptively modify the starting point for reading the data files depending upon the "success" rate of previous read operations. The success rate translates into increasing or decreasing a parameter representing the percentage of the data file which must be placed in data cache before the channel director can begin reading from the cache. The percentage varies between 50% and 100% to maintain a "success" rate between, preferably, 85% and 95%.
摘要翻译：一种用于从磁盘驱动器存储器检索数据文件的装置和方法，其提供重叠的读取操作，从而减少请求主机计算机看到的等待时间。主计算机请求检索数据文件，并且通道指导者将该请求放置在数据高速缓存中。如果数据文件不在数据高速缓存中，则磁盘控制器会将数据文件从磁盘驱动器读取并传输到数据高速缓存。在将数据文件传送到数据高速缓存中的某一点上，磁盘引导器将开始读取消息放置在数据高速缓存中，然后由通道指导器读取。在接收到开始读取消息时，通道指导器开始从数据高速缓存读取数据文件，从而当磁盘引导器完成将数据文件写入数据高速缓存时从数据高速缓存读取数据。渠道主管可以根据先前的读取操作的“成功率”自适应地修改读取数据文件的起始点。成功率转化为增加或减少表示数据文件百分比的参数，该数据文件必须放置在数据高速缓存中，才能从缓存开始读取信道。百分比在50％至100％之间变化，以保持“成功”率，优选在85％至95％之间。

摘要： A method of providing synchronized operational information for a host computer and an attached storage system is provided. The method includes providing a trace buffer in a memory of the storage system. A special command is created which allows a host computer to write information to the provided trace buffer. The special command uses a command from the communication protocol command set is a specific way in order to effectuate the trace buffer entry. The trace buffer entry will have a time component based on the storage system time clock. Thus, host activity may be synchronized in time with the storage system activity. In addition to the trace buffer, a statistics table is provided which maintains a log of which applications programs running on specific hosts, accessed the devices of the storage system.

摘要： A method and apparatus for improving the data storage reliability of a host computer writing to a disk storage device receive a plurality of blocks of data from the host computer and write the blocks of data, according to a selected format, in a high speed cache memory. The data blocks in cache memory are then written to the disk drive, the blocks having a defined size. A plurality of the blocks form a sector on the disk drive and a plurality of the sectors form a track on the disk drive. Writing to the disk includes, transparently to the host, the calculation and attachment to each block of an error correcting code value. When data is written to the data cache, there is generated and associated with each of a group of the blocks of data, from the host computer, a second error code. The second error code is stored at a physical location in the cache memory, and when written to disk, is further written at a location which is not in the same sector as any of the blocks with which the second codes are associated. In this way, the host to cache level communications acquires a higher degree of reliability than previously available for full block transfer under, for example, the UNIX operating system.
摘要翻译：一种用于提高主计算机向磁盘存储设备写入的数据存储可靠性的方法和装置从主计算机接收多个数据块，并根据所选格式将数据块写入高速缓冲存储器。高速缓冲存储器中的数据块然后被写入磁盘驱动器，这些块具有确定的大小。多个块在磁盘驱动器上形成扇区，并且多个扇区在磁盘驱动器上形成轨道。写入磁盘包括透明地对主机，计算和附加到每个块的纠错码值。当数据被写入数据高速缓存时，从主计算机生成并与一组数据块中的每一个相关联的第二错误代码。第二个错误代码被存储在高速缓冲存储器中的物理位置处，并且当写入到磁盘时，被进一步写入与第二代码相关联的任何块不在同一扇区中的位置。以这种方式，主机到缓存级通信获得比以前可用于例如UNIX操作系统下的全块传输更高的可靠性。

摘要： A mass storage array, having a plurality of mass storage drives, is flexible and adaptable to receive data blocks of a preselected varying size and, using an initialization process, adapts itself for writing the data blocks to disk drives having a known physical congfiguration. The disk storage system is software initialized to enable it to receive, from a host computer, data blocks having one of a selected number of possible block sizes. The disk storage system then, under software control, reformats the data to the particular configuration and physical block size of the disk drives attached to it. Thus, in one example, data blocks having 504 bytes per block, available from a Unisys mainframe computer, can be formatted and stored in disk drives having a block size of 512 bytes per block in a manner transparent to the user. In other configurations, a software configuration for the same physical storage controller and disk array takes data blocks from a Unisys Series A System having a data block size of 180 bytes per block, and groups them so that eight incoming computer formatted 180 byte blocks are stored in three physical blocks on the disk drive system.
