    • Migrating a data-processing entity from a source software image installed on a mass memory of the data-processing entity to a target software image stored on an external source. A portion of mass memory is released. Memory blocks stored in boot locations of the target software image are relocated to the released portion, including memory blocks required to boot the data-processing entity to load a streaming function for downloading the target software image from the external source. The data-processing entity is booted from the boot blocks, thereby loading the streaming function. Each request for reading a selected memory block of the target software image is served by the streaming function, which downloads the selected memory block from the external source and stores it into the released portion when the selected memory block is not available in the mass memory, or retrieves the selected memory block from the mass memory.
    • 将数据处理实体从安装在数据处理实体的大容量存储器上的源软件映像迁移到存储在外部源上的目标软件映像。 大量存储器的一部分被释放。 存储在目标软件映像的引导位置的存储器块被重定位到释放部分,包括引导数据处理实体加载用于从外部源下载目标软件映像的流传输功能所需的存储器块。 数据处理实体从引导块引导,从而加载流传输功能。 用于读取目标软件图像的所选存储块的每个请求由流功能服务,流功能从外部源下载所选存储块,并且当所选存储块在大容量存储器中不可用时将其存储到释放部分中, 或从大容量存储器检索所选择的存储块。
