NTA Getting Started Home

Updated: September 13, 2017

SolarWinds NTA stores NetFlow data in the NTA Flow Storage Database. The following table lists the minimum hardware requirements for the NTA Flow Storage Database.

Type Requirements
CPU 3 GHz or faster
Evaluation requires 2 CPUs
Production environments require 4 CPUs or more (4 - 16 CPUs)
RAM Evaluation requires 8 GB or more
Production environments require 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 7200 RPM disk or more

With the default 30-day retention period and default top talker optimization that records only those flows that represent conversations requiring the most bandwidth on your network, you should plan at least 8 GB of additional storage capacity per sustained 1000 flows per second. The required hard drive space strongly depends on your flow traffic, and SolarWinds recommends you provide more space accordingly.
NTFS file system required

The only RAID configurations that should be used with SolarWinds NTA are 0 or 1+0. 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 2008 SP2 and later.

.NET Framework


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