摘要： A server of an elastic computing cloud system includes a block device driver apparatus and at least a block device service apparatus. The server implements a hot deployment for a storage service, such that an upgrade of the storage service may be performed without interrupting the storage service. The block device driver apparatus maintains a waiting queue and a pending queue for each storage service. In response to determining a storage service will perform an upgrade, the block device driver apparatus stops processing data write/read requests that are maintained in the pending queue for the service, and puts the data write/read requests that are currently processed in the pending queue back to the waiting queue for re-dispatching, thus realizing completion of processing the upgrade of the storage service in the elastic computing cloud system without interrupting the storage service.

摘要： The present disclosure introduces a method and an apparatus of shrinking virtual hard disk image file. The present techniques search a garbage data block in a file and revise a record of the garbage data block in a block allocation table (BAT). The file includes one or more data blocks and a BAT that records information of each data block. The garbage data block is a data block that does not store effective data. The present techniques move an effective data block subsequent to the garbage data block, revise a record of the effective data block in the BAT after the moving, and shrink a size of the file after the movement.

摘要： Embodiments of the present application relate to a method for scheduling virtual disk input and output (I/O) ports, a device for scheduling virtual disk I/O ports, and a computer program product for scheduling virtual disk I/O ports. A method for scheduling virtual disk I/O ports is provided. The method includes assigning a set of service quality ratings to a corresponding set of virtual disk I/O ports based on a set of reading-writing bandwidth quotas associated with the corresponding set of virtual disk I/O ports in a physical machine, determining a total forecast value of a data bandwidth to be used by reading-writing requests and determining virtual disk I/O ports, allocating reading-writing bandwidth limits to the virtual disk I/O ports, and scheduling virtual disk I/O ports on the physical machine.
摘要翻译：本申请的实施例涉及一种用于调度虚拟磁盘输入和输出（I / O）端口的方法，用于调度虚拟磁盘I / O端口的设备以及用于调度虚拟磁盘I / O端口的计算机程序产品。提供了一种调度虚拟磁盘I / O端口的方法。该方法包括基于与物理机器中的相应虚拟磁盘I / O端口组相关联的一组读写带宽配额来将一组服务质量等级分配给相应的虚拟磁盘I / O端口组，通过读写请求和确定虚拟磁盘I / O端口来使用的数据带宽的总预测值，为虚拟磁盘I / O端口分配读写带宽限制，并在物理上调度虚拟磁盘I / O端口机。
