[san-tech][03118] Slidecast: "IO Turbine Launches Accelio SSD Accelerator for Virtualization", 05.24.2011, insideHPC,com

IO Turbineについての The Registerの解説記事です：
"IO Turbine claims to turbo-charge storage I/O"
 5th June 2011
  http://www.theregister.co.uk/2011/06/05/io_turbine_accelio/

  "Comment IO Turbine says its Accelio software accelerates
   virtualised server-storage I/O better than any other flash
   cache-using product by being implemented as a hypervisor plug-in.
   Close to the seat of ESX power, it gets its work done faster."
.....
  "Firstly, there are a number of caching products emerging -
   LSI CacheCade and Gridiron are just two recent ones. How does
   IO Turbine differ from these?"



LSI MegaRAID CacheCade software

GridIron

.....
Hypervisor plug-in
  "Accelio is implemented as a software plug-in to the hypervisor.
   What are the benefits of this?  Does it mean more VMs can be
   supported? Is latency reduced? How does this hypervisor plug-in
   approach make Accelio better?"
.....
VMware vMotion
  "With reference to Accelio supporting vMotion, we thought this is
   vMotion within the physical server hosting the VMs and not
   vMotion between physical servers, since Accelio uses cache in
   a physical server. We asked IO Turbine to spell out the reasons
   why competing caching technologies don't or can't fully support
   vMotion."
