Open the CIPO recordAbstract From the Canadian patent
A dynamically expandable and contractible fault-tolerant storage system permits variously sized storage devices. Data is stored redundantly across one or more storage devices if possible. The layout of data across the one or more storage devices is automatically reconfigured as storage devices are added or removed in order to provide an appropriate level of redundancy for the data to the extent possible. A hash-based compression technique may be used to reduce storage consumption. Techniques for freeing unused storage blocks are also disclosed.

Why it's free to use
- Filed November 4, 2005 and granted January 3, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 4, 2025.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
