Facebook servers and cold storage in action

Facebook's North Carolina data center is one of two facilities currently hosting its deep archival storage in a new way.

Like any enterprise, Facebook deals with a glut of data -- some (very) frequently accessed and high-value, but the majority archival and depreciating in value.

The tiered approach reduces the energy and storage capacity needed for archived content, without affecting user experience.
