High-availability clustersare the computer clusters which are implemented with the purpose of providing high accessibility to the cluster services. These high performance computing clusters are commonly known as HA clusters or failover clusters. These clusters function by using the redundant computers or nodes which are used to provide high performance services when the existing system components fail. Normally what happens is if a server crashes, the application will not be available to the user until the experts fix the crashed server. But in case of high performance computing cluster system the solution is provided by detecting hardware/software faults, and without any gap the systems are restarted on another system. These systems do not require any administrative intervention. This process is known as Failover. Generally the high-availability clusterutilizes all the possible techniques to make the systems as reliable as possible. For making this happen they use the techniques such as: • Disk mirroring: With the utilization of this technique the failure of internal disks does not result into the system crashes. • Redundant network connections: With the use of this technique the interface failures for single cable, switch, or network do not result in network outages. • Redundant Storage area network or SAN data connections: With this technique the single cable, switch, or interface failures do not lead to loss of connectivity to the storage. • Redundant electrical power inputs: This technique is used on different circuits so that single power feed, cable, UPS, or power supply failures do not lead to loss of power to the system. Using all these features minimizes the chances of clustering failover and ensures high quality services that the system requires.This high-availability cluster is often used for critical databases, file sharing on the network, customer services and business applications. So, if you are dealing in all these services and need a powerful solution for your systems then hire an expert and avail this high performance computing clusterservice and have a safe networking system. This article has been written by Gyan for the discuses on the high performance computing cluster and its deference with high availability cluster.
