 Fusion-io VSL (Virtual Storage Layer) 関連の、大学との新しい共同研究の
発表がありました (プレスリリース時に別の共同研究が報告されていました)。


まずは Fusion-io VSL (Virtual Storage Layer) のプレスリリース：

"Fusion-io Continues Its Innovation Leadership by Introducing First
 Flash-Optimized Subsystem"
 July 21, 2010

  http://www.fusionio.com/load/media-docsPress/tm1mj/press_release_optimus_prime.pdf

  "...today announced the release of a new flash-optimized OS
   subsystem called the ioMemory VSL (Virtual Storage Layer).
   The ioMemory VSL is the first and only OS subsystem that
   combines the benefits of the traditional I/O subsystem
   (block-level reading and writing) with the benefits of the
   virtual memory subsystem - virtualizing ioMemory devices and
   offering a "fusion" of both memory and storage."

.....
  ""Fusion's ioMemory VSL allowed us to develop a flash-optimized
   file system called DFS that outperforms ext3 by 20 percent for
   direct access and over 149 percent for buffered access. It
   delivered up to 250 percent higher application performance in
   benchmarks while reducing CPU overhead," said William Josephson,
   a PhD student at Princeton University working under Kai Li,
   founder of Data Domain."

Abstract
  "... We propose there is a new class of higher order storage
   primitives beyond simple block I/O that high performance solid
   state storage should support."
.....
  "... In this work we provide a proof of concept implementation of
   atomic-write on a modern solid state device that leverages the
   underlying log-based flash translation layer (FTL). We present
   an example of how database management systems can benefit from
   atomic-write by modifying the MySQL InnoDB transactional storage
   engine. Using this new atomic-write primitive we are able to
   increase system throughput by 33%, improve the 90th percentile
   transaction response time by 20%, and reduce the volume of data
   written from MySQL to the storage subsystem by as much as 43% on
   industry standard benchmarks, while maintaining ACID transaction
   semantics.
