Rack Mounted Server Clustering

A rack mounted server cluster is a group of physical servers with identical content, networked together to form a single virtual server. Requests directed to the virtual server can be handled by any physical server in the cluster. Clustering enables transparent growth: physical servers can be added without externally-visible network changes. Clustering improves fault-tolerance: a physical server can be taken down for maintenance or repair without resulting in a service outage. A server cluster can exhibit high-availability and throughput characteristics far beyond those achievable by even the largest single server.

Utilizing Load Balancing

For a server cluster to achieve its high-performance and high-availability potential, load balancing is required. Load balancing optimizes request distribution based on factors like capacity, availability, response time, current load, historical performance, and administrative weights. A load balancer sits between the Internet and a physical server cluster, acting as a virtual server. As each request arrives, the load balancer makes near-instantaneous intelligent decisions about the physical server best able to satisfy each incoming request. A well-tuned adaptive load balancer ensures that customer sites are available 24x7 with the best possible response time and resource utilization.
