- 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).
