Hi All,

On behalf of the Nexenta Team, I'd like to announce the very first
distribution with pNFS support. NCP3-pNFS experimental release is a
distribution that uses the pNFS code drop by the opensolaris team[1].
This build is based on b121 of opensolaris.

Download from:
http://www.nexenta.org/projects/site/wiki/DownloadExperimental

Setup Instructions:
http://www.nexenta.org/projects/site/wiki/PNFS

The Nexenta project is excited with this new technology. Being on
the forefront of storage distributions, we will be making available
more builds in the near future, and finally integrate the technology
into the NCP mainline.

You can checkout the latest sources via
hg clone http://hg.nexenta.org/pnfs-gate

pNFS
---

pNFS improves on the well known NFS protocol by allowing data access
from multiple machines to improve access time and bandwidth. From
official site [0]:

"Parallel NFS (pNFS) is a part of the NFS v4.1 standard that allows
clients to access storage devices directly and in parallel. The pNFS
architecture eliminates the scalability and performance issues
associated with NFS servers in deployment today. This is achieved by
the separation of data and metadata, and moving the metadata server
out of the data path.

"pNFS is important because it brings together the benefits of parallel
I/O with the benefits of the ubiquitous standard for network file
systems (NFS). This will allow users to experience increased
performance and scalability in their storage infrastructure with the
added assurance that their investment is safe and their ability to
choose best-of-breed solutions remains intact."

Note: This is an _experimental_ build, and as such is not ready for
production, and you can report issues on the project site [2]. We
welcome your contributions to the project.
