Supports: NPM 11.5

Important: These system requirements define the minimum requirements for all products on Orion Platform 2015.1. Products may have different requirements, such as OS or memory, and may differ per license level.

For additional information on requirements and configurations, see the Orion Common Components Guide. You should also review your product administration guides and release notes for the exact product requirements beyond these minimums.

We also recommend reviewing the NPM 11.5.3 Release Notes.

Hardware requirements

The following table lists minimum hardware requirements and recommendations for your Orion system.

Hardware requirements are listed by SolarWinds NPM license level.


SL100, SL250, SL500



CPU speed

2.0 GHz

2.4 GHz

3.0 GHz

For production environments, quad core is recommended.

Do not enable Physical Address Extension (PAE).

Hard drive space

2.5 GB

5 GB

20 GB

Two 146 GB 15K (RAID 1/Mirrored Settings) hard drives are recommended with a dedicated drive for the server operating system, Orion product installation, and tempdb files.

The Orion installer needs 1 GB on the drive where temporary Windows system or user variables are stored.

Some common files may need to be installed on the same drive as your server operating system. You may want to move or expand the Windows or SQL temporary directories.


3 GB minimum

4 GB minimum

8 GB minimum

Software requirements

The following table lists minimum software requirements and recommendations for a SolarWinds NPM installation.

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

  • SolarWinds does not support installing SolarWinds products on domain controllers.
  • SolarWinds neither recommends nor supports the installation of any Orion product on the same server or using the same database server as a Research in Motion (RIM) Blackberry server.


Software Requirements

Operating system

Production Evaluation Only
  • Widnows Server 2003 R2 SP2 (32- or 64-bit)
  • Windows Server 2008, 2008 SP2, 2008 R2, 2008 R2 SP1
  • Windows Server 2012 and 2012 R2
  • Windows 7

IP address version


IPv6 implemented as a dual stack. For more information, see RFC 4213 - Basic Transition Mechanisms for IPv6 Hosts and Routers.

CIDR notation is not supported for IPv6 addresses.

Web server

Microsoft Internet Information Services (IIS), version 6.0 or higher, in 32‑bit mode.

  • DNS specifications require that host names be composed of alphanumeric characters (A-Z, 0-9), the minus sign (-), and periods (.). Underscore characters (_) are not allowed. For more information, see RFC 952 - DOD Internet Host Table Specification.

The following Windows accounts, as configured by IIS 6.0 on Windows Server 2003 with their default security settings, are required: 

  • IUSR_<hostname> as a member of the Guests group ONLY.
  • IWAM_<hostname> as a member of the IIS_WPG group ONLY.

Disabling these accounts or changing any default settings of these accounts may negatively affect the operation of your Orion installation. SolarWinds strongly recommends against altering these accounts or their settings.

.NET Framework

Both .NET 3.5 SP1 and .NET 4.0.3 are required

Web console browser

  • Microsoft Internet Explorer version 8 or higher with Active scripting

  • SolarWinds Syslog Service
  • SNMP Trap Service
User privileges

SolarWinds recommends that administrators have local administrator privileges to ensure full functionality of local SolarWinds  tools. Accounts limited to  the Orion Web Console do not require administrator privileges.

Orion SQL database requirements

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

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

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 without SP, 2008 SP1, 2008 SP2, 2008 SP3, or 2008 SP4
  • SQL Server 2008 R2 without SP, 2008 R2 SP1, 2008 R2 SP2, 2008 R2 SP3
  • SQL Server 2012 without SP, 2012 SP1 (also with AlwaysOn Availability Groups), or with SP2
  • SQL Server 2014 (also with AlwaysOn Availability Groups)
  • The FullWithSQL installer package automatically installs SQL Server 2008 R2 SP1 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 Can I install my Orion server or Additional Polling Engine and my Orion database (SQL Server) in different locations across a WAN?
  • If you are managing your Orion database, SolarWinds recommends you install the SQL Server Management Studio component.
  • Use the following database select statement to check your SQL Server version, service pack or release level, and edition:

select SERVERPROPERTY ('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')

SQL Server collation
