"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."

Storage done virtually
