Old Legacy Server Sizing

Anuview Flow has been tested and certified to support up to 1000 concurrent devices or up to 40k flows/s from < 20 devices.

Below we can see as more devices are added to the system, the supported flow rate decreases in proportion.

The server must support at least 300MB/s sustained for both read and write to support the peak device or flow count. Failing to do so will result in dropped flow details.

A base installation should have 4GB or RAM available for the OS and and additional 50MB per device to monitor. More ram will always improve performance e.g

Number Of Devices	Min Ram
10	4.5GB
100	9GB
500	29GB
1000	54GB

As Anuview Flow is based on the Postgres database, overall performance is also dependent on CPU performance.

There is little gain going beyond 8 cores however more powerful CPUs would provide a better experience. Intel XeonX5680 3GHz or Core i7-3770S 3GHz would be recommended as a minimum.
