Deployment of a software image on multiple targets with streaming technique

摘要

A solution is proposed for deploying a software image from a source data- processing system on a plurality of target data-processing entities of a target data- processing system, the software image comprising a plurality of memory blocks being individually accessible, with a predefined subset of the memory blocks defining a bootstrap module. A corresponding method (400) comprises the steps of downloading (406) the bootstrap module onto a main one of the target data- processing entities from the source data-processing system, booting (407-409) the main target data-processing entity from the bootstrap module thereby loading a streaming driver comprised in the bootstrap module, serving (410-422) each request of accessing a selected memory block of the software image on the main data- processing entity by the streaming driver, the streaming driver downloading (413- 414) the selected memory block from the source data-processing system and storing (415-416) the selected memory block into the main target data-processing entity in response to a first one of the requests of accessing the selected memory block, or accessing (417) the selected memory block in the main target data-processing entity otherwise, providing (423-427) the bootstrap module to each one of a set of secondary ones of the target data-processing entities, booting (428-429) each secondary target data-processing entity from the bootstrap module thereby loading the streaming driver, and serving (430-448) each request of accessing a further selected memory block of the software image on the secondary data-processing entity by the streaming driver, the streaming driver retrieving (433-440) the further selected memory block from the main target data-processing entity and storing (441- 442) the further selected memory block into the secondary target data-processing entity in response to a first one of the requests of accessing the further selected memory block, or accessing (443) the further selected memory block in the secondary target data-processing entity otherwise.
