2.2 Meeting All Server Software and Hardware Requirements

Before installing OES, ensure that your system meets the following requirements:

2.2.1 Server Software

As you install OES, do not change any of the Base Technologies package selections, such as Java support. Doing so can cause various problems, such as the installation failing or one or more OES services not working properly.

2.2.2 Server Hardware

Table 2-1 Server Hardware Requirements

System Component

Minimum Requirements

Recommended Requirements


Any server-class computer that runs with AMD64 or Intel* EM64T processors.

IMPORTANT:OES only runs on x86_64. Other processors that are supported by SLES 12 SP2 or later, such as Itanium (IA64) and Intel x86(IA32), are not supported for running OES services.

NOTE:Services such as SMS and NRM run in 32-bit mode on a 64-bit platform.


2 GB of RAM

4 GB of RAM for the base system. Additional RAM might be required depending on which OES components are selected and how they are used.

Free Disk Space

10 GB of available, unpartitioned disk space

16 GB of available, unpartitioned disk space. Additional disk space might be required, depending on which OES components are selected and how they are used.

DVD Drive

DVD drive if installing from physical media

Network Board

Ethernet 100 Mbps

IP address

One static IP address

Subnet mask

Default gateway



USB or PS/2

Server computer BIOS

Using a DVD installation source, prepare the BIOS on your server computer so that it boots from the DVD drive first.

Video Card and Monitor

1024 X 768 resolution or higher with a minimum color depth of 8 bits (256 colors)

Although it is technically possible to run the ncurses installation at a lower resolution, some informational messages aren’t displayed because text strings don’t wrap to the constraints of the window.

NOTE:The RAM and disk space amounts shown here are for system components only. The OES service components that you install might require additional RAM and disk space.

Be sure to complete the planning instructions in the OES 2018 SP2: Planning and Implementation Guide for each component that you install.
