Do you put a lot of value on mission-critical servers and rely on them heavily to run your business? Server downtime can be costly! A down Exchange or SQL Server can easily cost thousands, or tens of thousands, of dollars in lost productivity.
Achieving the degree of reliability and availability demanded by mission-critical business requirements is expensive to create and support. We have found that the challenge for our clients is to learn what level of IT service availability is justified by their own price of downtime.
“High availability” refers to the characteristics and redundancies of IT infrastructures that make them available to users even in the event of a disruption. Many of our clients choose clustering to achieve high availability.
Simply defined, a cluster is a group of computers working together to run a common set of applications and to present a single logical system to the client and application. The computers in the cluster are physically connected by local-area network (LAN) or wide-area network (WAN) and programmatically connected by cluster software. These connections allow workloads to fail over to another computer in the cluster in the case of network failure of scheduled maintenance, for example. This is an option not available to stand-alone computers.
