Auxiliary database

Description

An auxiliary database is an optional, horizontally scalable database that expands the NSP storage capacity for demanding operations such as statistics collection, and performs the data aggregation required for NSP Analytics.

The database is deployed on one station, or in a cluster of three or more stations, depending on the scale requirement. In a multi-station auxiliary database, load balancing and data replication among the stations provide high performance and robust fault tolerance.

Auxiliary databases support DR deployment consists of two matching auxiliary database clusters that are deployed in separate data centers.
