This ensures a common authorization framework for services as they fail over from one node another. A computer cluster is a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system. All rights reserved. Those servers that are linked together through cluster services acts as one system and the connected servers are called “nodes”. Though each server cluster has its own resources, it is displayed in the network under one host name and has only a single IP (Internet Protocol) address. Cluster management server constantly sends heartbeat signals to both nodes to check whether if anyone is failing. The cluster management server is always available on the cluster. A server cluster is proven to be more reliable, scalable and effective than using a single computer. Also, if the shared storage isn’t redundant, after a storage failure, the SQL Server database will be unavailable. Privacy Policy   |   Terms   |   Disclaimer   |   Faq   |   Refund Policy. Cluster can also span different OS type. A failover cluster is a group of independent computers that work together to increase the availability and scalability of clustered roles (formerly called clustered applications and services). Note. The server instances that constitute a cluster can run on the same machine, or be located on different machines. Each server included in a server cluster is said to own and control its local devices. Understanding Server Clusters . Some cluster management software provides HA for virtual machines (VMs) by pooling the machines and the physical servers they reside on into a cluster. A failover cluster is a group of computer servers physical or virtual (or both) that are configured to provide continual access with no downtime or an absolute minimum of downtime.
