摘要： A storage management technique involves: receiving a request for creating a virtual volume, the request at least indicating a size and a service level of the virtual volume; in response to the request, creating the virtual volume on a first storage device; storing metadata information of the virtual volume in a local database that is accessible to the first storage device, the metadata information at least comprising identification information of the virtual volume and identification information of the first storage device; and synchronizing the metadata information to at least one second storage device. Such a technique enables more flexible creation of virtual volumes on a cluster of storage device.

摘要： Techniques for copying data involve: in response to receiving a request for copying data in a source address to a destination address, sending a first query and a second query to a first array associated with the source address and a second array associated with the destination address; receiving, from the first array, a first identifier as a response to the first query, the first identifier indicating a first logical storage unit in the first storage array corresponding to the source address; receiving, from the second array, a second identifier as a response to the second query, the second identifier indicating a second logical storage unit in the second array corresponding to the destination address; and triggering, based on the first and second identifiers, an inter-array data copy to perform copying the data. The first and second identifiers are globally unique at least for the storage array being triggered.

摘要： Techniques manage a storage system. In such techniques, data types of data in multiple storage devices associated with the storage system are obtained. The multiple storage devices are divided into a first group of storage devices and a second group of storage devices according to the data types. A first processing ability of the first group of storage devices and a second processing ability of the second group of storage devices are determined separately. Data distribution is scheduled among the multiple storage devices on the basis of the first processing ability and the second processing ability. With such techniques, processing abilities of various storage devices in a resource pool may be balanced, so that workloads of various storage devices may be balanced and further overall response speed of the resource pool may be increased.

摘要： Embodiments of the present disclosure provide a cache system and associated method. The cache system includes a first pipeline module including a first plurality of sequential processing phases for executing a plurality of operations. The first plurality of operations is executed in response to Input/Output (I/O) requests of a first plurality of types for the persistent storage device, and each of the first plurality of operations is a common operation for the I/O requests of at least two of the first plurality of types. The cache system also includes a control module configured to: determine a first type of a first pending processing I/O request for the persistent storage device, and in response to the first type being one of the first plurality of types, cause the first pipeline module to be executed to process the first pending processing I/O request.

摘要： A data storage system has multi-core processing circuitry and processes data movement requests using a multi-threaded library component having an initial operation of invoking an underlying driver to read data, and subsequent operations of copying data, invoking an underlying driver to write data, and initiating additional data movement operations as necessary to complete data movement for an entire range of the data movement request. Core-affined threads are used to execute library component operations for data movement requests of associated per-core queues. Data movement requests are distributed among the per-core queues for parallel processing of the data movement requests by the respective core-affined threads, and the execution of a core-affined thread includes initially starting the thread on the affined core to perform the initial operation, and subsequently re-starting the thread on the affined core to perform each of the subsequent operations.
