IT Analytics Components
When you install IT Analytics, you are installing the following components:
Portal Server. The physical server on which the IT Analytics Portal Server software resides.
Portal Server Software. The binaries, SQL scripts, configuration files, and open-source and third-party software products needed to retrieve and render reporting data from the Reporting Database.
Reporting Database. The Oracle database stores all report data. The Reporting Database is usually installed on the Portal Server, but you can just as easily install it on a separate server, preferably a dedicated database server. These binaries are installed during the first step of the installation procedure.
Data Collectors. The software that collects report data about your backup servers and storage arrays. The Data Collector is usually installed on a separate server, but you can just as easily install it on the Portal Server, with one exception: if you use Veritas NetBackup you must install it on each Primary Server.
Because of the relationship between the Portal Server, the Portal Server software, and the Reporting Database, you need to install these Portal Server components at the same time. However, you can install the Data Collector separately.
