On Thursday the 14th dm-cache was presented to the FAST '13, the 11th USENIX Conference on File and Storage Technologies conference in San Jose California. This is one of the most distinguished storage conferences.
dm-cache is a joint project between CloudVPS and Florida International University. It is a caching module that can work with external storage and works from within the Linux kernel.
Dulcardo Arteaga, the PhD student that worked on this project, has presented it on the second day of the conference. The research used data from our live clusters in order to determine the right cache size and the right cache configuration. Using these results we can continue to improve performance for our customers.
