[san-tech][03213] Googleは GFSから新ファイルシステムに移行中

Date: Sat, 25 Jun 2011 22:53:31 +0900
-----------------------------------------------
ZDNet UKの Google Urs Hölzle博士, Google Fellow, Senior Vice President of
Operationsとのインタビュー記事です:

"Google: 'At scale, everything breaks'"
 22 June, 2011, ZDNet UK
  http://www.zdnet.co.uk/news/cloud/2011/06/22/google-at-scale-everything-breaks-40093061/
  http://www.zdnet.co.uk/news/cloud/2011/06/22/google-at-scale-everything-breaks-40093061/2/

.....
   Q:"What are Google's plans for the evolution of its internal
      software tools?"

   Urs Hölzle: "There's obviously an evolution. For example, most
   applications don't use [Google File System (GFS)] today. In fact,
   we're phasing out GFS in favour of the next-generation file system
   that is very similar, but it's not GFS anymore. It scales better and
   has better latency properties as well. I think three years from now
   we'll try to retire that because flash memory is coming and faster
   networks and faster CPUs are on the way and that will change
   how we want to do things"

Network Computing Reportの記事です:

"OpenFlow And Network Value"
 June 13, 2011
  http://www.networkcomputing.com/private-cloud/230600049?pgno=1

4ページもありますが、1ページは現存のネットワーク管理等々の問題点を議論
して、2ページ後半から

  "Enter OpenFlow. The announcement of OpenFlow has some people in
   networking optimistic that we are about to see a significant
   change in innovation and progress on network management. OpenFlow
   is a nascent networking specification that has three key elements:
   a software controller, the OpenFlow protocol and a client on the
   network device. It's important to comprehend that all three elements
   combine to create a single coherent solution."
