DataDirect Networks (DDN) is a privately held data storage company,[2] and is headquartered in Chatsworth, California, USA.

[3] DDN provides storage for applications such as cloud storage services, supercomputing, life sciences and genomics, seismic processing, financial service trade and risk analysis, film production, live television broadcast, manufacturing, and video surveillance.

[7] With the explosion of “Big Data,” Alex Bouzari and Paul Bloch realised that a wider "transformative" event was happening in IT, and that HPC-class storage would be needed for high-end analytics and data processing, with lightning-fast IO, and the ability to scale to much higher capacities.

[11] DDN created DataDirect Networks Federal, LLC, in 2005 - formalizing a team which holds the necessary clearances to support the company's focus on the U.S. government and intelligence community.

[12] In 2008, DDN reported that it had exceeded $100 million in annual revenue and claimed to provide storage systems for 48 of the top 100 supercomputers – with customers including Argonne National Laboratory and the NASA Ames Research Center.

[18] In June 2018, DDN acquired the Lustre filesystem storage team from Intel, reviving the Whamcloud brand.
