UT25000 or UT50000


CPU Speed

4-core CPU, 2.5 GHz or better

Hard Drive Space

2 x 146 GB 15k (RAID1)

A RAID 1 drive for server operating system, SolarWinds installation, and tempdb files is recommended. The SolarWinds installer needs 1GB on the drive where temporary Windows system or user variables are stored. Per Windows standards, some common files may need to be installed on the same drive as your server operating system.


16 GB

The following table lists software and hardware requirements for your Orion Platform database server. SolarWinds UDT license levels are provided as a reference.


UT2500, UT5000, or UT10000

UT25000 or UT50000


SQL Server

SQL Server 2012, SP1, SP2, SP3

SQL Server 2014, SP1, SP2

SQL Server 2017

  • Either mixed-mode or SQL authentication must be supported.
  • If you are managing your SolarWinds UDT database, SolarWinds recommends you install the SQL Server Management Studio component.
  • If your SolarWinds UDT product installs SQL Server System CLR Types, a manual restart of the SQL Server service for your SolarWinds UDT database is required.
  • 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')

CPU Speed

8-core CPU 3 GHz or better.

Hard Drive Space

200GB 15k (RAID 1+0)

Due to intense I/O requirements, a RAID 1+0 drive is strongly recommended the SQL Server database and SolarWinds UDT data and log files. RAID 5 is not recommended for the SQL Server hard drive. The SolarWinds UDT installer needs at least 1GB on the drive where temporary Windows system or user variables are stored. Per Windows standards, some common files may need to be installed on drive as your server operating system.



The Configuration Wizard installs the following required x86 components if they are not found on your SolarWinds UDT database server:

  • SQL Server System Common Language Runtime (CLR) Types. SolarWinds 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

Additional requirements

Enterprise-level SolarWinds UDT deployments with the potential for more than 50,000 ports may need additional computing resources above the standards required for SolarWinds common components:


Additional Requirements

Up to 50,000

No additional requirements

More than 50,000



By adding individual polling engines, you can transparently scale your SolarWinds UDT installation to any environment.
