Panasas, Inc. is a privately held data storage company that specializes in high-performance scale-out network-attached storage for technical computing environments. Founded in 1999 by Garth Gibson and William Courtright, Panasas is a data storage company headquartered in Sunnyvale, California. The company initially started with venture capital funding from Mohr Davidow Ventures (MDV) and additional investors include the Carlyle Group, Centennial Ventures, Evercore Partners, Goldman Sachs, Intel Capital and Novak-Biddle Venture Partners. Its first products were shipped in 2004. After an estimated 20 customers, Victor M. Perez became chief executive in August 2004. Faye Pairman (previously of Applied Micro Circuits Corporations 3ware division) became chief executive in 2011. Panasas developed an extension for managing parallel file access in the Network File System (NFS). This work was later integrated in Parallel NFS (pNFS), part of the NFS version 4.1 specification, published by the Internet Engineering Task Force as RFC 5661 in January, 2010. pNFS describes a way for the NFS protocol to process file requests to multiple servers or storage devices at once, instead of handling the requests serially.
