This is very performant java shared memory off-heap caching solution we use for our image download servers.

An average server (2 x Intel Xeon E5620, 64 GB RAM) using this technology, combined with out one-nio framework served more than 70000 http requests, making more than 3000 Mb per second of real production traffic.

Thanks to use of shared memory, cached data are preserved on restarts of the server and could be preserved across reboots of OS with some scripting.

You can read some more details about it here http://habrahabr.ru/company/odnoklassniki/blog/148139/
