Panasas, Inc. is a private computer storage company. It specializes in high-performance scale-out network-attached storage optimized for Linux clusters.


Founded in 1999 by Garth Gibson and William Courtright, Panasas is an enterprise 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.[1] Faye Pairman (previously of Applied Micro Circuits Corporation's 3ware division) became chief executive in 2011.[2]


Panasas developed an extension for managing parallel file access in the Network File System (NFS).[3] This work has later been 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.[4] Panasas also released a client for a new protocol in 2007 which it called DirectFlow.[5]

Panasas supports NFS, Parallel NFS and Server Message Block (also known as CIFS) data access protocols to integrate into existing local area network infrastructures. Panasas blade servers manage metadata, serving data for NFS and CIFS clients using 10 Gigabit Ethernet.[6]

Panasas claimed to be the world's highest performance storage system in 2009.[7] Panasas systems are primarily designed for storage environments in the energy, government, finance, manufacturing, bioscience and higher education industries.[8]


The ActiveStor product line is a computer appliance which provides network-attached storage using a computer cluster to provide scalability using a technique known as "scale-out".[9] The ActiveStor 14 systems use solid state drive acceleration for improved metadata and small file performance, up to 1.5 GByte/s per shelf.[6] ActiveStor 11 and 12 systems (announced in 2011) claim from 600 MByte/s to up to 1.5 GByte/s per shelf.[10]


The PanFS clustered file system creates a single pool of storage under a global filename space to support multiple applications and workflows in a single storage system with high performance for technical applications.[11] PanFS supports DirectFlow (pNFS), NFS and CIFS data access protocols simultaneously.[12]
