"From a software perspective, the SSA includes the GlusterFS 3.2
release running on Red Hat Enterprise Linux 6.1. GlusterFS 3.2 is
the most recent stable release of Gluster, as developers are
currently pushing forward with the 3.3 release, which will provide
additional Big Data capabilities. On the Linux side, however, Red
Hat updated RHEL to version 6.2 earlier this week.
Trainer did not specifically state why the SSA is not using the
most recent version of RHEL.
