SevOne Hot Standby Appliance

SevOne High Availability Architecture
For organizations where an outage or disruption in performance data collection and reporting is not an option, SevOne provides a high availability solution option. The SevOne distributed peer-to-peer architecture supports geographicaly distributing appliances which increases both availability and scalability. Optional redundant appliances can also be deployed to further increase collection and reporting availability, on a per appliance basis.

SevOne Hot Standby Appliance
Using the same hardware and software as a primary appliance, a SevOne Hot Standby Appliance (SevOne HSA) is configured to store all the current and historical data of the primary that is replicated to it. The SevOne HSA maintains the same data in flash memory cache and disk storage in sync with the primary appliance. While in standby mode, the SevOne HSA does not perform any active monitoring itself and therefore it places no additional strain on the network.

In the case of primary appliance failure, the SevOne HSA assumes the primary appliance's polling and reporting responsibilities, typically in less than 30 seconds.  After failover and failback occurs, all historical data is still available for reporting, alerting and forecasting from the standby appliance. In other words, historical reporting is not impacted by a primary appliance failover.
