FREMONT, Calif., May 21 /PRNewswire/ -- Panasas, Inc., the leader in
parallel clustered storage solutions for the High Performance Computing
(HPC) market, today announced the source code release of key components of
its industry leading parallel file system client software, DirectFLOW(R),
to accelerate the adoption of Parallel Network File System (pNFS), which is
to be released as part of the NFS version 4.1 standard. This open source
initiative continues the company's leadership role in shaping the pNFS
standard which was originally initiated by Dr. Garth Gibson, Panasas
founder and chief technology officer.
Parallel NFS is a breakthrough technology that will solve storage I/O
bottlenecks and accelerate customer deployments of parallel storage
solutions. pNFS is a critical part of NFS version 4.1 (NFSv4.1), the first
major performance upgrade to the widely deployed NFS in over a decade.
Panasas' DirectFLOW protocol is a precursor to the pNFS standard and
provides all of the functionality expected to be available in the protocol
when it is formally reviewed by the Internet Engineering Task Force (IETF)
later this year. Given the close technical collaboration with the
industry-wide pNFS development team and eight years of experience in
parallel file system development, Panasas will be the first supplier to
offer fully pNFS compatible parallel storage systems.
To accelerate the industry's adoption of the standard, Panasas will be
releasing the source code this summer and has opened a fourth R&D center
which is dedicated solely to advancing solutions based on the new pNFS
"Parallel storage based on pNFS is the next evolution beyond clustered
NFS storage and the best way for the industry to solve storage and I/O
performance bottlenecks," said Robin Harris, senior analyst of the Data
Mobility Group. "Panasas was the first to identify the need for a
production grade, standard parallel file system and has unprecedented
experience in deploying commercial parallel storage solutions."
Driven by end customer demands for greater performance due to increased
use of parallelism from cluster and multi-core processor deployments, the
storage industry is moving to parallel storage to dramatically improve
application performance and to lower overall development costs. For
parallelism to become ubiquitous, a standards approach which allows users
to choose from multiple storage vendors and the freedom to access parallel
storage from any client are required.
Later this year, the IETF NFSv4 subcommittee will conclude its work on
the protocol as part of the NFS version 4.1 Request For Comment (RFC). pNFS
enables direct parallel data transfer between clients and storage devices.
Support is expected on Linux, Windows, and the leading UNIX versions from
the major computer vendors. This new standard is being jointly developed by
storage industry technology leaders and members of the NFSv4 working group,
including Panasas, IBM, EMC, Network Appliance, Sun Microsystems, and
University of Michigan's Center for Information Technology Integration
"Panasas has been the leading supplier of parallel storage solutions
for many years. By open sourcing our DirectFLOW client software, we will
accelerate customer adoption of next generation high performance storage
solutions based on the new Parallel NFS standard," said Victor Perez,
Panasas chief executive officer. "With this release of source code, we will
help the industry to solve some of the hardest problems in parallel file
Panasas has been a leader in the development of the pNFS standard from
the start. Dr. Garth Gibson co-authored the standard's initial problem
statement in 2004. Panasas has provided substantial technical input to the
NFSv4 committee working on pNFS and is contributing to the Linux NFS client
and server as well as to the Linux object storage driver, iSCSI driver, and
SCSI stack. The concepts for the pNFS proposal were derived from the
Panasas DirectFLOW protocol, which is a core component of the Panasas
PanFS(TM) parallel file system.
"Panasas led much of the early effort to create a Parallel NFS
standard," said Peter Honeyman, scientific director of the Center for
Information Technology Integration (CITI) at the University of Michigan.
"We are very pleased to see Panasas' continued commitment by adding
critical IP and development resources to the Linux open source reference
implementations of pNFS that we are building here at CITI."
The Panasas' DirectFLOW protocol currently provides essentially all of
the functionality expected to be available in the NFSv4.1 RFC later this
year. DirectFLOW will become the foundation of the Panasas pNFS solution.
Users and application developers can take immediate advantage of the
commercially proven Panasas parallel storage system today.
Panasas will be open sourcing code of the DirectFLOW client for Linux
to the storage and developer community, specifically, the object layout
driver and iSCSI drivers. The code will be available to the storage
community on the Panasas Web site, http://www.panasas.com, and at
http://www.pnfs.com. Current Panasas customers can access early releases of
the code from the Panasas customer support Web site later this summer.
Panasas, Inc., the global leader in parallel storage solutions, helps
commercial, government and academic organizations accelerate their time to
results leading to real world breakthroughs that improve people's lives.
Panasas' high-performance storage systems enable customers to maximize the
benefits of Linux clusters by eliminating the storage bottleneck created by
legacy network storage technologies. The Panasas ActiveStor Parallel
Storage Clusters, in conjunction with the ActiveScale(R) Operating
Environment and PanFS(TM) parallel file system, offer the most
comprehensive portfolio of storage solutions for High Performance Computing
(HPC) environments. Panasas is headquartered in Fremont, California. For
