"Red Hat Rolls Out Storage 2.0 Software"
 Second version of storage appliance includes features for object-based storage
 and big data
 April 09, 2012, Informationweek
  "The beta version of Red Hat Storage 2.0 has a number of new features
   that make managing unstructured CIFs, NFS, and GlusterFS mount
   points easier. It allows both file and object-based access to data
   within a single storage pool, support for Hadoop deployments
   in big data environments, and performance enhancements such as
   rebalancing of workloads, tuning improvements, and NFS optimization."
  "Instead of using a metadata server, the Red Hat Storage 2.0 uses
   a hashing algorithm to locate data in the storage pool. This
   capability allows it to remove I/O bottlenecks and a single
   point of failure."
  "Further, the Red Hat Storage 2.0 provides synchronous
   and asynchronous local and geographically distributed replication
   for data protection and disaster recovery."

"Red Hat clustered storage goes beta"
 A veritable Gluster... well, you know
 9th April 2012, The Register
  "The secret sauce in GlusterFS is what it calls an elastic hashing
   algorithm, which is an alternative to having a single, chokepoint
   metadata server at the heart of the file system as many clustered
   file systems do. GlusterFS 2.0 could scale to more than 500 x86
   server nodes implementing the file system and spanning petabytes of
  "Sarangan Rangachari, general manager of storage at Red Hat, tells
   El Reg that GlusterFS does not yet understand tiering on non-volatile
   storage, but that Red Hat's engineers are looking at how this
   might be used to goose the I/O performance of GlusterFS.

   Rangachari also wants to remind everyone that GlusterFS has
   a native access client, called Fuse, which has some performance
   benefits compared to the NFS and CIFS mount points, and that
   Red Hat is now trying to quantify what these performance benefits are
   as it hardens the code for Red Hat Storage 2.0.

   At the moment, Rangachari says, the Fuse client can deliver about
   twice the oomph serving up files compared to NFS and CIFS -
   but of course the benefit of NFS and CIFS is that Windows, Linux,
   Unix, and other operating systems speak these. They have to be taught
   to speak Fuse."
