About DDN (DataDirect Networks)
DDN, short for DataDirect Networks, makes high-performance storage for AI and supercomputing. Its EXAScaler product is built on Lustre, a parallel file system that spreads data across many servers so thousands of processors can read and write at once, and its newer Infinia platform targets AI data pipelines. DDN was founded in 1998 by Alex Bouzari and Paul Bloch, is privately held, and is headquartered in Chatsworth, California. Blackstone Tactical Opportunities announced a $300 million investment in January 2025.
DDN (DataDirect Networks) was founded in 1998 and is based in Chatsworth, CA, United States. It is listed under Memory & Storage, HPC & AI Systems. Reported funding is $300M from Blackstone, Jan 2025.

What DDN (DataDirect Networks) works on
Memory & Storage
Memory and storage hold the data that processors work on. Memory such as DRAM is fast and loses its contents when power is removed. Storage such as flash (NAND) is slower, cheaper per bit and keeps data without power.
HPC & AI Systems
High-performance computing (HPC) means using very large clusters of processors working together to solve problems that one machine cannot handle in a reasonable time. These clusters are called supercomputers. They run weather models, physics simulations and, increasingly, AI training.
