Top 10 questions to ask high availability vendors
It’s not easy to separate hype from reality. When evaluating a high availability and disaster recovery solution, ask vendors these questions to determine the best solution for you.
Will the solution:
- perform a failover that is transparent to the user – meaning users do not have to reboot their workstation or restart their application?
- check the overall health of the server prior to installation to ensure ongoing server reliability?
- feature an installation process that does not require the failover server to be manually pre-configured?
- offer complete data protection – ensure both the data and the registry can be rolled back?
- protect from failures caused by the application, data, operating system, network, hardware – and site disasters?
- work in a WAN environment to protect from complete site failure?
- offer both a manual and automatic failover/fail-back?
- be easy to maintain – what IT resources are required during upgrades, failovers and switchbacks?
- protect the primary application (e.g. Exchange) AND the auxiliary applications out-of-the-box, such as anti-virus, archiving, back-up, anti-spam, and fax products?
- allow for comprehensive failover testing – including the application, Active Directory, DNS updates and network connectivity?
