High availability is crucial to many applications. Despite using high-quality hardware and superior connection, any node (network, server, storage equipment, etc) is still subject to crashes due to power shortages, communication and equipment faults, fire incidents, maintenance problems or a human factor. These crashes result in a loss of all active connections and data transactions, as well as service termination. The main goal of Failover is to protect company server against such cases.

See example configuration of Multipath I/O on Open-E Data Storage Software. To run the Multipath I/O on DSS V6 with Windows 2008 server, perform the following steps: 1) Hardware configuration 2) Configure the DSS V6 3) Multipath I/O on DSS V6 with Windows 2008.

Failover Cluster allows multiple computers work together in order to provide high availability of some services. In case of a situation when a node responsible for a service fails, the second one is able to take over this service and prevents from an unexpected downtime.

Making regular backups is a necessary but laborious and time consuming task. As the amount of information increases, the process becomes longer and even more cumbersome. Ultimately the question of data integrity arises: How reliably can backups be restored and how fast can mission critical systems be brought back online?
