Db2 11.5 system requirements

The IBM Software Product Compatibility Reports (SPCR) pages are a complete source of hardware requirements, supported operating systems, prerequisites and optional supported software, with component-level details and operating system restrictions. This topic provides direct links to reports for Db2® 11.5 releases.

Hardware embedded full virtualization and Db2 11.5

Db2 supports hypervisors fully embedded in hardware and firmware when operating system requirements are met. Some examples are systems equipped with Power Hypervisor, VMware ESX 3i, or Hitachi Virtage.

Note: Any enhancements in hypervisor function that come in the form of separate software are not included in the definition of "Hardware Embedded".

Db2 11.5 (non-pureScale) runs on any operating system (OS) that is virtualized by any virtualization technology. Hypervisors in use must run a supported enterprise OS (For example, KVM with RHEL Enterprise support. KVM running CentOS is not recommended).

OS virtualization that supports Db2 11.5 is available to enterprise-ready and licensed hypervisors that have the write-thru feature enabled.
Note: This statement does not apply to Db2 pureScale® clusters in any Db2 releases. For a detailed list of supported virtualization for pureScale, refer to the reports for each release.
If IBM believes that an issue is specific to a virtualization technology (such as performance or communication with peripheral and hardware components), IBM might require that the customer reproduce the issue in a non-virtualized configuration. Due to the nature of virtualization technologies, IBM cannot guarantee levels of performance that are impacted by a customer’s virtualized deployment. Similarly, IBM cannot guarantee resolutions to issues that are caused by a customer’s virtualized deployment.
