Supports: NTA 4.1

SolarWinds NTA requires:

  • Appropriate SolarWinds NPM version hosted on the same server
  • NTA Flow Storage Database
  • Microsoft SQL Database
  • For production environments, SolarWinds recommends that SolarWinds NPM, Microsoft SQL Database, and NTA Flow Storage Database are hosted on separate servers.
  • SolarWinds NTA requires a 64-bit operating system.

Polling engine requirements

The following requirements ensure the scalability benefits of SolarWinds NTA:

Type Requirements
Operating system

64-bit operating system

If you have more than one poller, make sure they are all installed on 64-bit operating systems.

SolarWinds NPM

Version 11.5

Databases

Microsoft SQL Server 2008 and later

SQL Server 2008 Express and earlier restricts the size of any database to 4 GB. For this reason, SolarWinds does not support using SQL Server 2008 Express and earlier with SolarWinds NTA in production environments.

In SQL Server 2008 R2 Express and later, Microsoft increased the restriction of maximum database size to 10 GB. You can use these versions in production environments if your flow storage requirements do not exceed 10 GB.

The NTA Flow Storage Database is where SolarWinds NTA stores your flow data. If you decide to store flows on a remote server, which SolarWinds recommends for production environments, you must install the NTA Flow Storage Database there first.

A connection to Orion SQL database is required, because CBQoS data and some additional low level details are still stored in Orion SQL database.

NTA Flow Storage Database requirements

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.
  • 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
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 NTA 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.

Operating system

64-bit Microsoft Windows Server 2008 and later

.NET Framework 4.5

Port requirements

The following table lists ports that SolarWinds NetFlow Traffic Analyzer uses to communicate with other devices and servers.

Application Port Protocol Usage
80 TCP Port used for web console and any other web servers.
161 TCP Port used for polling CBQoS-enabled devices.
1433 TCP Port used for communication between the NTA Flow Storage Database and the existing SQL server.
2055 UDP Port for receiving flows on any SolarWinds NTA collector.
17777 TCP Port for sending and receiving traffic between SolarWinds NPM and other Orion Modules.
Device-specific   Any port required by a specific device.

Virtual machine requirements

SolarWinds NTA may be installed on VMware Virtual Machines and Microsoft Virtual Servers if the following conditions are met in your virtual environment:

  • Each virtual machine needs to meet the SolarWinds NPM requirements for virtual machines. For more information, see the SolarWinds Network Performance Monitor Administrator Guide.
  • Each installation of NPM should have its own dedicated network interface controller.

SolarWinds NPM uses SNMP to monitor your network. SNMP traffic is generally assigned low priority, and thus you can experience gaps in monitoring data.

Orion SQL database requirements

Your Orion Platform product and your SolarWinds Orion database should use separate servers.

Multiple SolarWinds Orion server installations using the same database are not supported.

These minimum requirements are for the Orion Platform. Products that run on the Orion Platform may have different requirements, such as different OS or memory requirements. Consult your product-specific documentation for the exact requirements.

The following table lists software and hardware requirements for your SolarWinds Orion database server using SolarWinds NPM license levels as a reference.

Requirements SL100, SL250, SL500 SL2000 SLX

SQL Server

SolarWinds supports Express, Standard, or Enterprise versions of the following:

  • SQL Server 2008, 2008 SP1, 2008 SP2, 2008 SP3, or 2008 SP4
  • SQL Server 2008 R2, 2008 R2 SP1, 2008 R2 SP2, or 2008 R2 SP3
  • SQL Server 2012, 2012 SP1, or 2012 SP2 (also with AlwaysOn Availability Groups)
  • SQL Server 2014 (also with AlwaysOn Availability Groups) or 2014 SP1
  • The FullWithSQL installer package automatically installs SQL Server 2014 Express. This is recommended for evaluations.
  • Set the recovery model of the database to Simple. SolarWinds does not support other methods.
  • SQL Server Compact Edition 3.5 SP2 is only supported for evaluations.
  • Due to latency effects, SolarWinds does not recommend installing your SQL Server and your Orion server or additional polling engine in different locations across a WAN. For more information, see Install SolarWinds software and SolarWinds database (SQL Server) across a WAN.

SQL Server collation

  • English with collation setting SQL_Latin1_General_CP1_CI_AS
  • English with collation setting SQL_Latin1_General_CP1_CS_AS
  • German with collation setting German_PhoneBook_CI_AS
  • Japanese with collation setting Japanese_CI_AS
  • Simplified Chinese with collation setting Chinese_PRC_CI_AS

We support CI database on an CS SQL Server.

We do not support case-sensitive databases.

CPU speed

Dual quad core processor, 3.0 GHz or better

Dual quad core processor, 3.0 GHz or better

Dual quad core processor, 3.0 GHz or better

Hard drive space

20 GB minimum

Mirrored drives for the OS and 6 disk RAID 1+0 for database data files is recommended.

50 GB minimum

Mirrored drives for the OS and 6 disk RAID 1+0 for database data files is recommended.

100 GB minimum

SolarWinds recommends the following configuration:

  • A hardware RAID Controller with a battery backed-up write back cache
  • Disk Subsystem 1 Array 1: 2 x 146 GB 15K disks RAID 1 (mirroring) for the OS
  • Disc Subsystem 2 Array 2: 2 x 146 GB 15K disks RAID 1 (Pagefile + Extra Storage)
  • Disk Subsystem 3 Array 3: with 6x 15k 146 GB or 300 GB disks configured in a RAID 1+0 array to allow for maximum write performance for your SQL MDF and FILEGROUPS.
  • Disk Subsystem 4 Array 4: with 4x 15k 146 GB or 300 GB disks configured in a RAID 1+0 array to allow for maximum write performance for your SQL LDF Transaction LOG file

Due to intense I/O requirements, a RAID 1+0 drive is strongly recommended for the SolarWinds database, data, and log files. RAID 5 is not recommended for the SQL Server hard drive.

Per Windows standards, some common files may need to be installed on the same drive as your server operating system.

Memory

4 GB minimum

8 GB recommended

8 GB minimum

16 GB recommended

16 GB minimum

32 GB recommended

Authentication

Either mixed-mode or SQL authentication

Other software

If you are managing your SolarWinds Orion database, SolarWinds recommends you install the SQL Server Management Studio component.

The Installation Wizard installs the following required x86 components if they are not found on your Orion database server:

  • SQL Server System Common Language Runtime (CLR) Types. Orion products use secure SQL CLR stored procedures for selected, non-business data operations to improve overall performance.
  • Microsoft SQL Server Native Client
  • Microsoft SQL Server Management Objects
