A Sun Modular Datacenter on display at the Sun Microsystems Executive Briefing Center in Menlo Park, California
Sun Modular Datacenter (Sun MD, known in the prototype phase as Project Blackbox) is a portable data center built into a standard 20-foot intermodal container (shipping container) manufactured and marketed by Sun Microsystems (which is now owned by Oracle Corporation). An external chiller and power are required for the operation of a Sun MD. A data center of up to 280 servers can be rapidly deployed by shipping the container in a regular way to locations that might not be suitable for a building or another structure, and connecting it to the required infrastructure. Sun Microsystems states that the system can be made operational for 1% of the cost of building a traditional data center.
In late 2003, employees of the Internet Archive wrote a paper proposing "an outdoor petabyte JBODNAS box" of sufficient capacity to store the then-current Archive in a 40' shipping container. The first implementation of the concept have been realized using Sun Microsystems' Modular Datacenters in March 2009.
