Open the CIPO recordAbstract From the Canadian patent
A system and method to allow scalability of file storage (300) in terms of capacity and performance through a symmetric multicomputer architecture with shared storage, in which storage and protocol processing resources can be added to (or removed from) the system without any need of recognizing and/or explicitly migrating the data stored in the system. The invention permits clients (302, 304, 306, 308) to access files stored (i.e. written) in any of multiple external protocol processing nodes to be retrieved from any other external protocol processing node. The access can be routed through any of the gateway service nodes (312a, 312b, 312c).

Why it's free to use
- Filed June 13, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 13, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
