Data-access protocols

With the OneFS operating system, you can access data with multiple file-sharing and transfer protocols. As a result, Microsoft Windows, UNIX, Linux, and Mac OS X clients can share the same directories and files.

OneFS supports the following protocols:

The Server Message Block (SMB) protocol enables Windows users to access the cluster. OneFS works with SMB 1, SMB 2, and SMB 2.1, as well as SMB 3.0 for Multichannel only. With SMB 2.1, OneFS supports client opportunity locks (oplocks) and large (1 MB) MTU sizes. The default file share is /ifs.
The Network File System (NFS) protocol enables UNIX, Linux, and Mac OS X systems to remotely mount any subdirectory, including subdirectories created by Windows users. OneFS works with NFS versions 3 and 4. The default export is /ifs.
The Hadoop Distributed File System (HDFS) protocol enables a cluster to work with Apache Hadoop, a framework for data-intensive distributed applications. HDFS integration requires you to activate a separate license.
FTP allows systems with an FTP client to connect to the cluster and exchange files.
HTTP and its secure variant, HTTPS, give systems browser-based access to resources. OneFS includes limited support for WebDAV.
Swift enables you to access file-based data stored on your EMC Isilon cluster as objects. The Swift API is implemented as a set of Representational State Transfer (REST) web services over HTTP or secure HTTP (HTTPS). Content and metadata can be ingested as objects and concurrently accessed through other supported EMC Isilon protocols. For more information, see the Isilon Swift Technical Note.
