SSDからみを数件。まずは DOE LLNL Hyperion Project関係：

"Appro Deploys a World Class Linux Cluster Testbed Solution to LLNL
 in Support of the Hyperion Project", 6/26/2010
  http://www.appro.com/press/view.asp?Num=193

  "LLNL created the Testbed solution for the National Nuclear Security
   Administration's Advanced Simulation and Computing program's
   Hyperion initiative," ... 

  "The Hyperion project will provide three critical objectives for
   high performance computing projects.
     First, it will enable computational scientists to have IO test
       beds for scalable parallel file systems such as Lustre and CEPH. 
     Secondly, it will allow the evaluation of large scale checkpoint
       restart mechanisms that don't depend on global scalable file
       systems. 
    Thirdly, it will facilitate investigation of cloud base file systems
       and analysis tools such as HADOOP and MAPREDUCE."

※Cephは、今までの Hyperion Project関係資料には出てなかったと思います。
Oracleの Lustre戦略の影響かもしれませんね。

新しい PCIe SSDボードが発表されました
"Virident Systems Introduces Industry's First SSD that Delivers the Highest
 Sustained Performance and Enterprise-class Reliability.", June 15, 2010
  http://www.virident.com/news_10_06_15.php

  "tachIOn is also the first product to bring together the necessary
   hardware and software technologies for a systematic build-out of
   server-side Tier-0 storage across an entire data center. Dubbed the
   Virident GreenCloud Storage Software, this capability will be released
   in phases to enable large-scale deployment of SSDs, which until now
   has been hampered by capacity fragmentation and inconsistent
   availability of SSD resources to applications that need them."

"Anobit breaks MLC flash barrier", 15th June 2010
  http://www.theregister.co.uk/2010/06/15/anobit_genesis/

  "Israeli startup Anobit reckons it has the technology in its Genesis
   enterprise SSDs to make flash storage practicable for all tier one
   data."

  "MLC flash is much cheaper per GB than SLC flash but is slower and
   wears out quicker. Anobit - another bit - has controller technology
   using what it calls Memory Signal Processing (MSP) technology to
   increase 2-bit MLC endurance up to SLC levels, with controller
   technology bringing the performance level up too."
