"Solarflare Releases EnterpriseOnload Application Acceleration Middleware"
 September 22, 2010
  http://www.solarflare.com/news/news_press_show.php?release=20100922a

  "announced today the release of its EnterpriseOnload application
   acceleration middleware. Solarflare’s EnterpriseOnload is a
   Linux-based, open source, high-performance application accelerator
   that reduces application latency by 50 percent and increases
   message rates by 3 to 4 times." ..... "The latest EnterpriseOnload
   release includes three new features important to customers:
   performance enhancements that deliver lower latency, 802.1Q virtual
   LAN (VLAN) trunking support for manageability and separation of IP
   traffic, and 802.1ad Link Aggregation support for higher bandwidth,
   load balancing and redundancy."


  "EnterpriseOnload distinguishes itself from OpenOnload through an
   annual subscription model, which includes a number of valuable
   benefits and services, such as validated source code, documentation,
   bug fixes and regular releases. Most importantly, EnterpriseOnload
   offers three levels of service and technical support that range from
   basic business day response to premium 24/7 worldwide support.
   Solarflare customers will continue to have access to OpenOnload from
   openonload.org."

  "... we finally got around to writing up an architectural introduction
   to OpenOnload.  As well as putting some written words to the diagrams
   of the talk, there is a serious message here, which is that true
   application transparency for POSIX with protocols like TCP isn't
   something that can be bolted on like an after-thought. So when Lee and
   friends next try to persuade you otherwise," ...
