SUSE Virtualization Options for SAP

When designing an infrastructure strategy for SAP environments on SUSE, the support landscape is defined by clear rules separating production compliance from non-production flexibility.

Core SAP Virtualization Rules

• Production Workloads: Official SAP validation is strictly required for any virtualization technology used in a production environment. To receive full SAP technical support, customers must utilize validated hypervisors such as SUSE KVM.
• Non-Production Workloads: SAP does not mandate or enforce a validated virtualization layer for non-production environments across development, testing, and sandbox workloads. Despite this flexibility, executing Dev/QA cycles on an unvalidated infrastructure stack introduces hidden operational risks that can directly threaten the stability of your ultimate production go-live.
• Support Limitations: Deploying an unvalidated virtualization layer for production workloads will result in a loss of SAP technical support for that specific environment.

Supported SUSE Hypervisors for SAP Production Environments

SAP officially recognizes and supports specific SUSE Linux Enterprise Server (SLES) for SAP applications virtualization products for live, production environments:

• SUSE KVM (Kernel-based Virtual Machine): Officially listed as a supported KVM-based virtualization product for production SAP on Linux environments.
• Unified Application Stack Support: SUSE KVM offers an infrastructure solution capable of supporting core SAP components, including SAP HANA, SAP S/4HANA, and NetWeaver Application Servers.
• Native, enterprise-grade foundation: SUSE KVM is embedded directly within the SUSE Linux Enterprise Server (SLES) for SAP applications subscription, eliminating the cost for a separate virtualization hypervisor.

Maintaining Environment Parity: Why SUSE KVM Should Span Your Entire SAP Landscape

While it can be tempting to explore alternative infrastructure platforms for non-production SAP environments to lower immediate licensing overhead, maintaining infrastructure parity across your entire enterprise landscape is a fundamental best practice. Standardizing on SUSE KVM across both production and non-production environments is the strongly advised path forward due to several critical operational realities:

• The Reality of Unvalidated Platforms: Introducing SAP workloads to an unvalidated platform creates an unrealistic expectation of functional stability. Without rigorous, collaborative testing, neither SAP nor the infrastructure vendor can guarantee system reliability, performance metrics, or technical support when issues arise.
• The Risk of Environmental Disparity: Utilizing a completely different infrastructure stack for Dev/QA than production introduces severe operational risk.
• Escalating Total Cost of Ownership (TCO): Splitting your architecture by introducing an unvalidated hypervisor layer for non-production environments forces your IT staff to manage two completely distinct sets of administration procedures, diagnostic tools, and technical skill sets. This fragmentation significantly increases operational complexity and drives up long-term TCO, negating any perceived short-term savings.

By standardizing on SUSE KVM from sandbox to production, your organization ensures total environment predictability, streamlined single-tool administration, and seamless compliance with SAP’s official support matrices.

VM Migration Tools

SUSE partners with Cloudbase Solutions to provide Coriolis as a validated migration solution, enabling seamless transitions from legacy environments, such as VMware vSphere, to KVM (specifically for the SAP workload).

Key benefits of the Coriolis integration include:

• Zero-Downtime Transitions: Supports non-disruptive, agentless “warm” migrations, allowing applications to remain online during data transfer and eliminating the need for long maintenance windows.
• Verified SAP Migration Path: Offers a specific, verified migration path for critical SAP application servers and SAP HANA databases, maintaining required enterprise stability and compliance.
