We have been running LizardFS for a while now, but only inside a testing environment. It will be deployed to production soon and it will help to make specific files available inside several datacenters in a very fast and efficient way. Normally you would buy very expensice enterprise storage solutions, but this open source software simply does the job well enough.

In addition, we have been running LizardFS within a second pilot environment for a couple of months now. It stores over one Million files across several servers, being located in different datacenters. So far, also this setup runs rock-solid, just as you would expect it to be.

Providing relatively cheap NAS solution with great scale-out functionality.
