Server sizing

SolarWinds SAM is capable of monitoring networks of any size, ranging from small corporate LANs to large enterprise and service provider networks. Most SolarWinds SAM systems perform well on 3.0 GHz systems with 4 GB of RAM using default polling engine settings. However, when monitoring larger networks, you should give additional consideration to the hardware used and the system configuration.

There are three primary variables that affect scalability. The most important consideration is the number of monitored components. Monitoring more than 1,000 components may require fine tuning for optimal performance. The second variable to consider is polling frequency. For instance, if you are collecting statistics more frequently than the default, the system has to work harder and system requirements will increase. Finally, the number of simultaneous users accessing SolarWinds SAM directly impacts system performance.

When planning a SolarWinds SAM installation, there are four main factors to keep in mind with respect to polling capacity: CPU, memory, number of polling engines, and polling engine settings.

Installing SolarWinds SAM and SQL Server on different servers is highly recommended, particularly if you are planning on having more that 1,000 component monitors. This scenario offers several performance advantages as the SolarWinds SAM server does not perform any database processing and it does not have to share resources with SQL Server.

If you plan to monitor 10,000 or more components, SolarWinds recommends that you install additional polling engines on separate servers to help distribute the work load. For more information about sizing SolarWinds SAM to your network, contact the SolarWinds sales team or visit
