• database space: depending on target network size, (for reference, typical data
volume = uncompressed raw measurement data /AP/month = circa 50MB)
• LAN connection

2.2 Sonar-server requirements
Sonar is a light end-point software for Sapphire active tests. Sonar server software can be
installed to dedicated server or virtual environment.
Eye will connect to the Sonar and run application tests towards it. Sonars can be installed into
several locations in the network to simulate the real-life situation where various business
services are geographically distributed.
The Sonar server requirements are below:
• x86 32-bit Intel and AMD processors
• LAN connection
• CentOS 5.4
There are no specific RAM or disk requirements as Sonar is truly a light-weight server software.
To best reflect the business-application behavior, Sonar server would benefit from similar
characteristics than the server running the business application. For example, the Windows
TCP/IP stack implementation may limit performance by default.
