NTA Flow Storage Database requirements

Table of contents

Updated September 13, 2016

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

Recommendations

  • Install the NTA Flow Storage Database on a different server than the SolarWinds Orion database. This way, the high amount of incoming flows will not affect the performance.
  • In case you want to use SAN storage, please make sure your environment meets the IOPS requirements for the NTA Flow Storage Database server.
  • Solid-state drives (SSD) are recommended for all components.
  • Do not install the NTA Flow Storage Database on a polling engine (main or additional) because it might affect performance.
  • Use a dedicated disk or LUN for storing your flows data. SolarWinds does not recommend installing the NTA Flow Storage Database on the C:\ drive.
  • 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
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, you should plan at least 8 GB of additional storage capacity per sustained 1000 flows per second. However, 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.

OS

64-bit operating system: Microsoft Windows Server 2008 R2 SP2 and later

.NET Framework

4.6.2

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