Panasas, Inc. is a privately-held data storage company that specializes in high-performance network-attached storage for technical computing environments.

History[edit]

Founded in 1999 by Garth Gibson and William Courtright, Panasas is a computer data storage product 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]

Technology[edit]

Panasas developed an extension for managing parallel file access in the Network File System (NFS).[3] 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.[4]

Panasas products utilize the proprietary DirectFlow[5] protocol, which is based on the pNFS standard and ideally suited for the high performance Linux clusters commonly found in technical computing environments.

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

Panasas systems provide data storage and management for high-performance applications in the biosciences, energy, media and entertainment, manufacturing, government and research sectors.[7]

ActiveStor[edit]

The ActiveStor product line is a computer appliance that integrates hybrid storage hardware, file system PanFS and network protocols. It uses a computer cluster to provide scalability, known as "scale-out".[8] ActiveStor systems combine high-capacity hard drives and solid state drives for improved mixed-workload performance with rapid access to small and large files alike. ActiveStor 20 was announced in August 2016 with increased capacity, using larger and faster disks.[9][10]

PanFS[edit]

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]

DirectFlow[edit]

DirectFlow is the parallel data access protocol designed by Panasas and delivered on ActiveStor products. DirectFlow avoids traditional protocol I/O bottlenecks by allowing compute clients to access Panasas storage directly and in parallel [13]

DirectFlow was originally supported on Linux, and expanded in April 2016 to support Apple MacOS. [14]
