REDHAT Enterprise Linux server (RHEL) is an Opensource. It is popularly used as Server Operating system.
RHEL6 have a lot of features:-
The advantages are
1- RHEL6 introduces the use of KVM (Kernel-based Virtual Machine) as its hypervisor. In the earlier releases Xen hypervisor was used. The main advantage of KVM is that a new kernel should not be installed like in Xen. It also supports the installation of many virtual operating systems like Windows, Linux, Solaris,etc. It is easy to manage.
2- Ext4 is made the default filesystem. Ext4 has many new advantages than Ext3 which is used in earlier versions of RHEL. Ext4 is comparatively faster and easy to manage. It supports supports up to 100TB with the addition of Scalable Filesystem Add-one.
3- Improved level of Security RHEL6 has advanced level of security. SELinux (Security Enhanced Linux) features are improved and a new set of SELinux rules has been added to provide security to virtual machines from hackers and attackers. This new feature is called SVirt.
4- New Networking Features RHEL6 is released with improved and new networking features. It supportsIPv6. It uses NFSv4 (Network File Transfer) for the sharing of files in the network rather than NFSv3. It also supports iSCSI (internet Small Computer System Interface) partitions. The network manager in RHEL6 supports Wi-Capabilities.
5- Use of Drivers RHEL6 has drivers for speeding up operations under KVM, VMware and Xen.
6- Increase in the support period provided by Red Hat. RHEL6 has a long period of support provided by Redhat. It provides updates for 7 years and also a extra 3 years of service as paid service. Therefore it means that its period of support is twice the period of support provided by other linux distributors like Ubuntu , Suse , Mendriva , Debian, etc.
7- Improvements of minor updates
Red Hat releases minor versions such as 6.1, 6.2. These minor versions are the accumulated updates of the major version. The new minor releases will not only contain bug fixes but will also have major changes and new features.
