Open Source Contributions

NetApp participates in standards bodies and industry associations to drive strategic industry technology directions.

We accomplish this through active leadership and participation in various organizations, driving key industry technology directions to ensure that emerging standards meet our business and architectural requirements, while demonstrating our commitment to interoperability and open-systems infrastructures.


NetApp has played a major role in advancing industry standards such as Network File System (NFS), Network Data Management Protocol (NDMP), Internet Small Computer System Interface (iSCSI), Fibre Channel over Ethernet (FCoE), Storage Management Interface Specification (SMI-S), Simple Public-Key GSS-API Mechanism (SPKM), Encryption Key Management Interchange Protocol (KMIP), and Cloud Data Management Interface (CDMI).


We continue to be active in the foundational storage standards of Small Computer System Interface (SCSI), Fibre Channel (FC), and Serial ATA (SATA). At the same time, we are driving new and emerging standards in cybersecurity, solid-state storage, non-volatile memory, power efficiency, virtualization, cloud computing, high-performance computing, and open-source initiatives.

NetApp believes in and supports the open source community and process, donating equipment, money, and code of our own as well as participating in several open source communities. We are concerned about open source license proliferation and therefore only license our code contributions using the same license as the open source project, or in the case of an independent contribution, a license that is widely used, usually GPL or BSD .

The following are some of the areas in which NetApp engages with the open source community:


As the basis of Clustered Data ONTAP , NetApp makes regular enhancements to the FreeBSD Project, presents technical papers and is an annual sponsor .


NetApp has made several contributions to iSCSI including the Linux drivers and daemon , as well as defining and writing the reference implementation of the SNIA management API .


We employ one of the Linux maintainers and regularly make bug fixes and enhancements. Of the identified companies, NetApp is tied for the seventh most active contributor to the 2.6.23 kernel. We are also on the board of directors of the Linux Foundation and participate in the XEN and OVA collaborative projects.


NDMJOB is an NDMP-compatible backup/restore package, reference implementation, and conformance test. It is furnished in source code form to the public by Traakan, Inc. and other contributors free of charge or restriction. NDMJOB may be used as a ready-to-run backup package, used in conjunction with other NDMP products, as the basis for new products, as a verification of NDMP products, and as a reference of the NDMP protocol standards and conventions.


NDMP (Network Data Management Protocol) is an open protocol for network based backup enabling multi-vendor backup solutions. NetApp has been a leading developer of the NDMP specification since the late 1990's and has donated significant software code contributions to the NDMP reference implementation code base.


With one of the members of the original NFS development team, co-authors of NFS Version 3 and Version 4, co-chair of the NFS Version 4 IETF working group, and the Linux NFS maintainer on staff, NetApp is a driving force in the NFS community. Our open source contributions include Linux's NFS implementation and a Linux client for pNFS that allows parallelization of data accesses.


nfsdump and nfsscan

The NFS/RDMA protocol specifications were jointly authored by NetApp, and a full implementation of the NFS/RDMA client and server for Linux were written or jointly developed by NetApp. In addition, we work with universities and researchers in the industry to advance NFS/RDMA and broaden its use. NFS/RDMA can provide dramatic performance benefits to clients and servers.
