Clustering is probably one of the most important features that you can enjoy with your Redhat subscription. You will be amazed to find out how Redhat included everything under one package. Being one of the leading providers of software solutions, you can expect only the best features from Redhat and one of them is Redhat clustering.
Clustering has been used by different administrators regardless of the type of environment. But there are times when common vendors do not provide the needed support, component or access that you need. In short, there are high chances if paying extra just to complete your setup. With Redhat, you get to access what you need without any unnecessary expenses. If you’re looking forward to establishing your own Redhat clustering, then you should know all about the important components.
Since clustering is all about connecting two or more computers to enhance the capability of a network environment in performing important functions, there should be a component that will control the most basic functions. A component called Cluster Infrastructure takes care of linking the different nodes together by identifying and managing memberships, denials, and other configurations. Passwords and locks are also managed by this component and if necessary, it executes fencing which removes defective or unnecessary nodes from a certain cluster.
To keep a system operational without any interruptions, administrators apply the principle of high availability Redhat clustering which is all about failing over services from one defective node to a fully functional one. A component called High Availability service management is required to establish this type of clustering.
After setting up a cluster, a component called Cluster Administration Tools will take care of managing and maintaining the configuration of the whole cluster. The other major components must be coordinated for it to work.
For a network environment to be effective and at the same time have cheap operations, a Linux Virtual Server is used to balance loading and identify how many nodes is needed for clustering. Therefore, administrators can avoid idle components and can maximize the use of the system. Aside from balancing the service requests among the nodes in a cluster, LVS assists in running redundant servers to efficiently distribute client requests.
Redhat clustering was designed to help enterprises have better internal control in their network. The components required to setup clustering are all included as you enjoy the full support provided by Redhat consultants and professionals.
