VNQM 2024.1 System Requirements

Release date: February 6, 2024

SolarWinds strongly recommends that you install the SolarWinds Platform on a server that is neither public, nor internet-facing. To learn about best practices for configuring your SolarWinds Platform installation securely, see Secure Configuration for the SolarWinds Platform.

Important: These system requirements define the minimum requirements for VoIP and Network Quality Manager 2023.4 as a single installed product. You may need to increase your requirements in small, medium, or large environments with multi-modules installed.

For additional information about requirements and configurations, see the Multi-module system guidelines. You should also review your product administration guides and release notes for the exact product requirements beyond these minimums.

  • Avoid using a license tier higher than SLA 5.
  • Do not monitor more than 500 Network Service Assurance operations.
  • Do not store more than 10k phone call history entries for approximately 300 registered phones.
  • Use default polling settings.

  • If you anticipate six million standard, device to device calls per month with a peak hour of 20,000 calls, we recommend using a dedicated SQL server with a 64-bit, 2.67 GHz quad-processor CPU and 16 GB of RAM. We do not support more than six million calls per month.
