Why should I choose SUSE Linux Enterprise Server instead of Microsoft Windows, Red Hat Enterprise Linux or Oracle Solaris?

SUSE Linux Enterprise Server is differentiated from other server operating systems by its interoperability and vendor recommendations.

SUSE Linux Enterprise Server is uniquely designed for maximum interoperability of more than just operating systems.

  • Since 2006, Microsoft and SUSE have been working together, specifically in the areas of cross-platform virtualization, identity and directory federation, and cross-platform systems management. Our joint goal is to ensure that SUSE Linux Enterprise Server environments and Microsoft Windows Server environments share data, communicate more easily with each other and can be managed with a common set of tools.
  • SUSE Linux Enterprise Server includes support for both Xen and KVM, making it easier for you to support and interoperate workloads on different hypervisors.
  • In networking, SUSE Linux Enterprise Server supports many advanced protocols such as IPv6, allowing you to connect more equipment.

Interoperability is part of a larger, more pragmatic, company-wide mission to give SUSE customers the ability to use the best technology in support of their business objectives. We recognize that heterogeneous data centers are today's reality, and we are committed to helping our customers maximize the utilization of their heterogeneous IT resources.

SUSE Linux Enterprise Server offers the strongest partner ecosystem of any enterprise Linux vendor. It is the only Linux server operating system recommended by Microsoft, SAP and VMware. Microsoft recommends SUSE Linux Enterprise Server to customers who run Windows and Linux in their data centers. This unique endorsement is made possible by the technical collaboration that exists between the two companies, together with joint support programs to ensure customers have seamless, comprehensive one-stop support for their virtual Linux and Windows services.


Similarly, SAP recommends SUSE Linux Enterprise as a preferred platform to customers who want to deploy SAP applications on Linux. Together, SAP and SUSE are reducing the complexity of application deployments, lowering costs and giving customers a single point of contact for acquiring and supporting a complete data center stack. VMware recommends SUSE Linux Enterprise Server for use in its virtual environments. SUSE Linux Enterprise Server is optimized for both VMware and Microsoft hypervisors to support mission-critical workloads.

How can I effectively track and manage my SUSE Linux Enterprise Server subscriptions and support entitlements?

Managing server subscriptions and support entitlements is easy with Customer Center and the Subscription Management Tool, included for free with each SUSE Linux Enterprise subscription.

SUSE Customer Center is a web-based portal that facilitates the registration, entitlement and tracking of SUSE Linux Enterprise subscriptions. SUSE understands that customers have many different kinds of employees who need access to customer support. SUSE Customer Center addresses those needs by providing all the information, tools and resources for the many customer contacts who have business and technical relationships with SUSE. This broad approach includes system administrators, IT managers, purchasers and others. System administrators can easily access system information, subscription registration, and the patches and updates they need to address security and support concerns. IT managers are able to view the entire scope of their software contracts, including expiration dates, to effectively plan their spending. Purchasing agents can handle their part of the ordering process while leaving more technical tasks to their IT staff. By combining product, service and support options for customer contacts, SUSE Customer Center simplifies administration, making it faster, easier and more cost-effective for companies to do business with SUSE.

The Subscription Management Tool for SUSE Linux Enterprise goes one step further by establishing a proxy system with repository and registration targets. This helps customers centrally manage software updates within their firewall on a per-system basis, while maintaining corporate security policies and regulatory compliance.

Can I upgrade my existing systems from SUSE Linux Enterprise 11 to SUSE Linux Enterprise 12?

Yes. You are entitled to upgrade any systems with an active SUSE Linux Enterprise subscription to SUSE Linux Enterprise 12. However, a direct upgrade or migration via bootable media is supported only from SUSE Linux Enterprise 11 Service Pack 3 on the same hardware architecture using the following methods:

  • Booting from an installation medium (ISO image)
  • Automated migration from SUSE Linux Enterprise 11 SP3 to SUSE Linux Enterprise 12

Can I use a single subscription of SUSE Linux Enterprise Server for multiple virtual machines?

Yes; we sell subscriptions that specifically support virtual environments. Only one subscription is required per physical server, regardless of how many virtual machine hosts or guests you intend to run on that physical server. All SUSE Linux Enterprise Server VMs on a single host, regardless of what's doing the virtualization, can use the same activation code for x86 and x86_64 architectures.
