[san-tech][03329] Linux 3.0で pNFSサポート?

Date: Sat, 06 Aug 2011 00:05:28 +0900
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
   vendors to include it in commercial releases."

Date: Fri, 05 Aug 2011 22:38:44 +0900
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."

   purpose is to provide a legal framework within which the greater
   cloud computing community of users and providers can reach consensus
   on a set of requirements for Open Cloud, as described in
   the Open Cloud Principles (OCP) document, and then apply those
   requirements to cloud computing products and services, again by way of

また Hadoop関連ですが、

"How Facebook moved 30 petabytes of Hadoop data"
 Jul. 27, 2011, GigaOM

  "... Today, it shared the latest of those innovations - moving its
   whopping 30-petabyte cluster from one data center to another."

  "... The move was necessary because Facebook had run out of both
   power and space to expand the cluster ? very likely the largest
   in the world - and had to find it a new home. Yang writes that
   there were two options, physical migration of the machines or
   replication, and Facebook chose replication to minimize downtime."
