So, SOMETIME in 2015, is basically what you are saying.   Wow that is a really tight timeline for a 60B USD/year company. Its been over a year since the last Linux HIT release (April 2014) and in terms of RHEL7 support: "Red Hat Enterprise Linux 7 (Maipo) is based on Fedora 19, upstream Linux kernel 3.10, systemd 208, and GNOME 3.8. The first beta was announced on 11 December 2013, and a release candidate was made available on 15 April 2014. On 10 June 2014 Red Hat Enterprise Linux 7 was officially released." Officially Rhel7 has been available for over a year, no support yet from Dell.  I hope that Dell realizes it is telling its Linux customers to go and shop elsewhere.    
When is support comming for RHEL 7 based installations ? We are getting ready to turn up a RHEL 7 based datacenter and we can't seem to find a HIT for Equallogic
