Panasas (http://www.panasas.com), a maker of high-performance storage systems and the creator of the Parallel Network File System (pNFS), announced its plans to open source its pNFS client software. The code, which should be available by the end of this summer, complements the company’s donation of pNFS to the Internet Engineering Task Force, which has incorporated the protocol into the Network File System 4.1 standard.
Pananas’s software, named DirectFLOW, implements all of the features of pNFS. To boost performance, pNFS separates data and metadata, and removes the metadata server from the data path between a client and storage. (See the pNFS home page, http://www.pnfs.com, for an architectural overview.) pNFS supports block, object, and file transfers.
The NFS 4.1 RFC (http://tools.ietf.org/wg/nfsv4) is being developed by Panasas, IBM, EMC, Network Appliance, Sun, and the University of Michigan. You can find the Panasas code at the company’s Web site and at the pNFS home page.
