Portal Server Architecture
Hitachi Storage Viewer uses a three-tiered architecture on the Portal Server(s):
• Web Server: Hitachi Storage Viewer embeds Apache and applies the latest set of Apache security patches to eliminate all known security vulnerabilities.
• Apache Tomcat: Hitachi Storage Viewer uses Tomcat as the Java Servlet engine. Hitachi Storage Viewer communicates between Apache and Tomcat using standard Apache connectors.
• Oracle 11g database: Hitachi Storage Viewer communicates with the Oracle 11g database using JDBC.
The Hitachi Storage Viewer Portal deploys Apache Tomcat on a single web server and the Oracle 11g database on its own dedicated system.
