How Junos Takes Hardware Clustering Redundancy To The Next Level

Server Clustering is the architectural design to create redundancy in a given production environment. This redundancy in clustering is achieved by creating one common pool of storage resources that all of the servers have access to. The major benefit behind server clustering and this pooling of resources is to increase resource availability such that if one of the nodes in the cluster were to fail, another node in that cluster could pick up and process the compute responsibilities of the failed server.

Further, in a clustered configuration, organizations benefit from consolidated resources, the ability to span projects over multiple nodes, and high availability are just a few benefits of node clustering. With clustering, organizations can minimize outages, optimize their resource allocation, and improve the monitoring and management of production environments.

What makes Junos clustering unique, though? Junos takes clustering a step further by utilizing a chassis cluster. In this configuration, pairs of devices can be linked together to represent a single node. In this case, if a single device fails, the entire node does not go down. Instead, because devices are configured redundantly, the node can failover to the operational device without that node experiencing downtime.
