Synchronous dual data center (SDDC) administration
This section explains how to plan, install, and administer a synchronous dual data center solution with Exasol.
A synchronous dual data center (SDDC) solution has one cluster stretched across two separate sites (data centers). This solution can provide business continuity with minimum downtime in case of a node failure or a complete outage on the primary site.
This section explains in detail how to set up, manage, and monitor a typical SDDC solution, and how this setup will maintain business continuity in some example node failure and disaster scenarios.
The example setup may differ considerably from your actual requirements and situation. If you are considering a synchronous dual data center solution, contact Exasol support first so we can analyze and advise if an SDDC is appropriate for your needs.
Incorrect configuration and administration of an SDDC cluster presents a high risk of data loss. When you install and administer an SDDC solution with Exasol, observe extreme caution and follow the provided instructions precisely.
If you have any doubts when performing a task described in this documentation, contact Support for guidance.
