RHEL 6.6 beta is released; draws major inspiration from RHEL 7
Just so RHEL 6.x users (who wish to continue with this branch of the distribution for a bit longer) don’t feel left out, Red Hat has launched a beta release of its Red Hat Enterprise Linux 6.6 (RHEL 6.6) platform. Taking much of its inspiration from the recently released RHEL 7, the move is directed towards RHEL 6.x users so that they benefit from new platform features. At the same time, it comes with some real cool features that are quite independent of RHEL 7 and which make 6.6 beta stand out on its own merits. Red Hat offers Application Binary Interface (ABI) compatibility for RHEL for a period of ten years, so technically speaking, it cannot drastically change major elements of an in-production release. Quite simply put, it can’t and won’t change an in-production release in a way that could alter stability or existing compatibility. This would eventually mean that the new release on offer cannot go much against the tide with respect to RHEL 6. Although the feature list for RHEL 6.6 beta ties in closely with the feature list of the major release (6.0), it doesn’t mean RHEL 6.6 beta is simply old wine served in a new bottle. It does manage to introduce some key improvements for RHEL 6.x users. To begin with, RHEL 6.6 beta includes some features that were first introduced with RHEL 7, the most notable being Performance Co-Pilot (PCP). The new beta release will also offer RHEL 6.x users more integrated Remote Direct Memory Access (RDMA) capabilities.
