先頃発表された Red Hat Enterprise Linux 6.2に pNFS関連が含まれています

Red Hat Enterprise Linux 6.2 - What's New

Parallel NFS (pNFS) in Technology Preview
Transfer rates faster than NFS support
*) pNFS is an extension of NFS that provides significantly larger data
   transfer rates compared to the traditional NFS architectures. This
   is achieved by processing the meta-data (a typical bottle neck for
   I/O throughput) separately from the actual data. By separating
   the meta-data and the data paths, pNFS allows clients to access
   storage devices directly and in parallel. pNFS is a part of standard
   NFS version 4.1 specification.
*) Support for pNFS is limited to client-side functionality for file
   layout only.

"Fusion-io Unveils ioCache Virtualization Solution"
 Fusion's ioTurbine Software and Customized ioMemory Accelerator
 Virtualizes Flash to Deliver Affordable Performance for
 Virtualizing Data-Intensive Enterprise Applications
 Aug. 29, 2011
  "When deployed in a VMware environment, Fusion's ioTurbine software
   dynamically provisions ioMemory capacity and I/O performance across
   multiple virtual machines (VMs) by using Fusion's VSL OS Subsystem
   to house and serve data for each VM.  Tight integration of VSL's
   host-based flash management and ioTurbine's cache management
   eliminates otherwise redundant mapping functions, maximizing I/O
   performance and adding a critical and previously missing piece
   to virtualized IT environments - a plentiful supply of scalable,
   low-latency I/O."

  "Through this approach, Fusion-io unites the benefits of flash and
   cache without the overhead costs created by integrating each
   technology through traditional architectures using storage
   protocols and embedded processors. This solution avoids the need
   for expensive, performance-oriented networked storage systems,
   SSD arrays and memory appliances that struggle to deliver
   performance from the far end of a network, instead allowing
   enterprises to use cost optimized shared storage systems."
  "Available exclusively in bundles with ioTurbine software,
   Fusion's ioCachedelivers 600GB of capacity optimized to support
   the majority of virtualized application workloads. "

  "NFS has been the standard protocol for NAS systems since the 1980s.

   demanding technical computing applications, NFS is no longer

  "Regular LEDs can be turned into optical WLAN with only a few
   additional components thanks to visible light communication
   (in short, VLC). The lights are then not just lighting up, they
   also transfer data. They send films in HD quality to your iPhone
   or laptop, with no loss in quality, quickly and safely."
  "... since scientists from the Fraunhofer Institute for
   Telecommunications, Heinrich Hertz Institute HHI in Berlin,
   Germany, have developed a new transfer technology for video data
   within the scope of the OMEGA project of the EU, its
   implementation in real life is getting markedly closer. At the
   end of May, the scientists were able to present the results of
   the project in Rennes, France. They were able to transfer data
   at a rate of 100 megabits per second (Mbit/s) without any losses,
   using LEDs in the ceiling that light up more than ten square
   meters (90 square feet). The receiver can be placed anywhere
   within this radius, which is currently the maximum range.

2011 Workshop on Architectures II: Exascale and Beyond: Configuring,
Reasoning, Scaling, 8/8/11 - 8/10/11

 "The goal for this workshop will identify ways that we can abstract
   architectures, in general, to meet the ever-changing complexities
   inherent in exascale (and beyond). This workshop will be essential
   in molding our path forward in hardware and software architectures
   design space exploration, including simulation and emulation modeling
   and their role in developing and implementing abstract machine models.
   Moreover, we believe that such methodologies will prove insightful
   in discovering what could and should be included or changed in next
   and future generation hardware. Scholars from both DOE and non-DOE
   communities will participate. Together we will identify machine
   abstractions, their idealized primitives, and view of memory. It will
   be informative to discuss and debate the realization of these
   abstractions. Moreover, given an existing real system and/or subsystem,
   how do we do explain its machine abstraction and would this abstraction
   be sufficient to explain the performance attributes of exascale?"

2011 Workshop on Architectures I: Exascale and Beyond: Gaps in Research,
Gaps in our Thinking

  "It has been approximately two years since DOE and DARPA completed their
   "ground breaking" exascale reports. In July 2010, the DARPA UHPC program
   was started. Four teams were funded to research and develop ExtremeScale
   designs. Various computer vendors have claimed that they are investigating
   the designs of exascale computers (IBM, HP and SGI). Several DOE labs are
   also investigating exascale designs (LBL, Sandia). The purpose of
   this workshop is to address the hardware and software architecture
   challenges for developing exascale computers. It would be very informative
   to revisit the exascale studies and explore what has been learned and
   to discuss research gaps. To achieve this goal we will meet and discuss
   the lessons learned from these various activities."

以前紹介した Linux 3.0

では全く触れてませんが、Panasasの Blogでは、

 July 29, 2011, Submitted by Barbara Murphy
  "...  Just to show that things do not move fast in the standards world,
   the IETF approved the first Internet Draft for the pNFS standard in 2008
   and finally by June 2011, pNFS for files and objects was only then
   included in latest kernel (version 3.0).

   The release of Linux Kernel 3.0 was a huge industry milestone.  Finally
   another hurdle to take full advantage of Parallelism has been removed
   with the standardization of pNFS as the long term file system of choice
   for HPC applications.  However it will likely be at least one more year
   before pNFS is in the hands of users as it still requires Linux software

Wikibonに CTOの David Floyer氏が、Erasure Codingについて投稿している

"Erasure Coding - The New Approach to Data Archiving"
 August 4th 2011, SiliconANGLE
  "Now, says Wikibon CTO David Floyer in a new article on,
   an emerging data archiving approach called Erasure Coding, based on
   a fairly complicated mathematical analysis, promises very secure data
   archiving in the public cloud at an order-of-magnitude less cost than
   the three-data-center approach. The trade-off is that data access is
   slower, although certainly much faster and easier than access to data
   archived on tape. And it avoids the issues of media obsolescence
   as well as deterioration that plague older tape-based data."

   there were two options, physical migration of the machines or
