Scalable image distribution in virtualized server environments

摘要

A method and system include replicating an image representing a sequence of bytes on a local storage medium on a target device by determining a similarity between images and reconstructing a new image using equivalent blocks from one or more similar images locally available on the target device or available on donor devices to reduce network link usage and transfer time in replicating the image.

1. A method, comprising:
replicating an image representing a sequence of bytes on a local storage medium on a target device by:
determining a similarity between images; andreconstructing a new image using equivalent blocks from one or more similar images locally available on the target device, or available on a best fit donor device if no similar images are locally available, wherein the new image represents a virtual machine (VM) template.
