The following table lists the minimum hardware requirements for the NTA Flow Storage database which is used for storing flow data in NTA.

  • Install the NTA Flow Storage database on a different server than the SolarWinds Orion database so the high amount of incoming flows will not affect the performance.
  • Do not install the NTA Flow Storage database on a polling engine (main or additional) because it might affect performance.
  • Use a dedicated disk for storing your flows data.
  • Do not run anti-virus software or any other file scanning application over data in the NTA Flow Storage database. File scanning applications affect the database performance and may even prevent the database from running properly.
Type Requirements
CPU 3 GHz or faster
4 CPUs or more (4 - 16 CPUs)
RAM 16 GB or more (16 - 128 GB)
To ensure optimal performance, you should increase RAM together with the database size.
Hard drive space
20 GB on a 7200 RPM disk or more

With the default 30-day retention period and default top talker optimization, plan at least 8 GB of additional storage capacity per sustained 1000 flows per second. However, the required hard drive space depends on your flow traffic, and SolarWinds recommends you provide more space accordingly.
NTFS file system required

Use RAID 0 or 1+0 with NTA. Other RAID or SAN configurations are not recommended, as they can result in data loss and significantly decreased performance.


64-bit operating system: Microsoft Windows Server 20016 SP1 and later

.NET Framework


If it is not already installed, .Net Framework auto-installs with the SolarWinds NTA Flow Storage Database.
