摘要： A method for operating a storage system, including storing data redundantly in the system and measuring respective queue lengths of input/output requests to operational elements of the system. The queue lengths are compared to an average queue length to determine respective performances of the operational elements of the storage system. In response to the average queue lengths and a permitted deviation from the average an under-performing operational element among the operational elements is identified. An indication of the under-performing operational element is provided to host interfaces in the storage system. One of the host interfaces receives requests for specified items of the data directed to the under-performing element, and in response to the indication, some of the requests are diverted from the under-performing operational element to one or more other operational elements of the storage system that are configured to provide the specified items of the data.

摘要： A method for data storage includes accepting write commands belonging to a storage operation invoked by a host computer, and caching the write commands in a volatile memory that is powered by external electrical power. A current execution status of the storage operation is also cached in the volatile memory. Responsively to an interruption of the external electrical power during the storage operation, the cached write commands and the cached execution status are backed up in a non-volatile memory. Upon resumption of the external electrical power, the backed up execution status is recovered, so as to resume the interrupted storage operation.

摘要： A method and system for efficiently accessing desired datasets among multiple datasets which are stored at specific data addresses within multiple storage subsystems which are coupled to a host system via a storage subsystem controller and a data channel. A data request is transmitted from the host system to the storage subsystems via the data channel. The data request specifies non-address attributes for desired datasets, such as boundary addresses for large data extents including many datasets or a request for all datasets modified since the occurrence of a specified event. The data request is then processed at the storage subsystem controller to determine a data address for each dataset within the storage subsystem which possess the desired attributes. Thereafter, the desired datasets are transmitted via the data channel to the host system in association with a specific address for each dataset. A selected status message is transmitted from the storage subsystem controller when no more datasets are located which possess the desired attributes. In this manner, the retrieval of data from a storage subsystem is greatly enhanced.
摘要翻译：一种用于有效地访问存储在多个存储子系统内的特定数据地址的多个数据集中的期望数据集的方法和系统，其经由存储子系统控制器和数据信道耦合到主机系统。数据请求通过数据通道从主机系统发送到存储子系统。数据请求指定所需数据集的非地址属性，例如大数据扩展区的边界地址，包括许多数据集，或者是自发生指定事件以来修改的所有数据集的请求。然后在存储子系统控制器处理数据请求，以确定具有所需属性的存储子系统内的每个数据集的数据地址。此后，期望的数据集通过数据信道与每个数据集的特定地址相关联地发送到主机系统。当不存在具有所需属性的更多数据集时，从存储子系统控制器发送所选择的状态消息。以这种方式，从存储子系统检索数据大大增强。
