Maintenance Notification:
On next Monday August 5th 2019 starting at 7am CEST we will conduct some maintenance. You might encounter some issues using the Exasol User Portal and Issue Tracker! We will restore the Exasol User Portal and Issue Tracker before 9am CEST on Monday August 5th 2019.

Exasol is designed for high-performance analytics and has certain requirements on the used hardware. General requirements and a minimal configuration are described in the Hardware and Network sections. Exasol also provides a list of standard and certified hardware in the Certified Hardware section. 

If you intend to deploy EXASolution in a non-certified environment, it will need to undergo a certification process by EXASOL to determine the extent of support provided for EXASOL products in the projected environment. Please be aware that the certification process is subject to extra charge.

Certification of a cluster setting (hardware, network and specific setup) usually includes functional, stress and performance tests.

The process is iterative and individual to the setting.


The customer provides EXASOL with a reference-environment consisting of at least three nodes. In order to qualify for the EXASOL certification process, the hardware environment must meet the Minimum Requirements for Hardware Certification.

Functional Tests

Functional tests include the following:

  • Installation of EXASuite and a basic configuration
  • Familiarization with hardware and infrastructure (for example, BIOS options for best practice advice)
  • Checks on the functionality of the hardware (for example, what happens if a component fails, if applicable)

Stress Tests

Stress and burn-in tests place the major hardware subsystems (CPU, RAM, disk) under heavy load to examine their stability and quality.

Performance Tests

EXASOL carries out disk and network tests to get an impression of the basic performance.

In addition, database level tests will be executed (for example, TPC-H benchmarks of appropriate scale factors).

Please note that the benchmarks don't allow statements about the performance of a specific scenario in everyday use. We thus encourage customers to develop a benchmark to baseline and monitor the underlying architecture. Such a benchmark should consist of typical writing statements and reading queries based on a fixed dataset.

Certification Results

The new certified hardware will be added to the list of certified hardware

In the case that a non-certified or only limited certified hardware or IT-environment (e.g. a shared or virtual environment) is used for EXASuite, operational malfunctions are possible. If you operate EXASuite on non-certified hardware or in a non-certified IT-environment, Exasol recognizes errors as defined in our terms and conditions only if they are reproducible on the standard hardware. Moreover, as it is not possible for us to properly analyze performance issues in a shared environment, they may not be recognized as errors. Please be aware, the same applies to the incident management: Exasol operation engineers will handle incidents from the operating system level only.
