  • RAM supported by RHEL6 is up to16TB.
  • File system up to 100TB with EXT4 file-system.
  • Very much optimized to support many hardware
  • Can control 90000 jobs/min(I believe it’s too good I’m loving it.)
  • SELinux sand-boxing for more SELinux control.
  • KVM for virtualization.
  • 7+3 years of extended support.
  • Lower Power consumption(20% less when compared to RHEL5) — A green initiate.
  • When handling Virtual machines(VM) RHEL6 on RHEL6 is good at performance when compared to RHEL5 vm on RHEL6 server
  • More Reliability, Availability, serviceability(RAS)
  • Rapid file system recovery(up to 10x faster than rhel5).
  • Resource management through Control group(CGroup) sand-boxing the process.
