SUSE Linux Enterprise Server for System z helps you achieve greater ROI, uptime and performance from Linux on the mainframe with these features:

Server consolidation

  • Add more workloads—not more expensive hardwareServer consolidation with SUSE Linux Enterprise Server for System z helps you save money and get the most from your mainframes. More ›
  • Server consolidation via z/VMTogether, SUSE and IBM have found a way to put Linux on the mainframe and reap the benefits of virtualization. By running SUSE Linux Enterprise Server with IBM's outstanding z/VM virtualization technology on IBM System z mainframes, you can virtualize servers, creating many virtual machines that run on a single processor and handle multiple workloads in parallel. By doing so, you reduce or eliminate the need to buy more hardware. Plus, server virtualization lets you consolidate physical systems, shrinking your data-center footprint and simplifying maintenance for your IT staff.
  • Run System z on your laptop for application development, testing, demoThe IBM System z® Personal Development Tool (zPDT) is the technology behind several exciting new application development tools for the IBM System z platform. The zPDT can enable a virtual System z architecture environment that allows select mainframe operating systems, middleware and software to run unaltered on x86 processor-compatible platforms. IBM System z Personal Development Tool (IBM zPDT) 1.3 is officially supported by IBM and SUSE. More from IBM ›

Support for Integrated Facility for Linux

  • Support for Integrated Facility for LinuxAn IFL is a specialized processor from IBM that handles multiple Linux workloads. IFLs let you buy a single software license and share it across many Linux virtual machines. This makes Linux on the mainframe even more affordable. Because you are charged for only one processor license, running Linux workloads on an IFL doesn't result in increased IBM software charges for traditional System z operating systems and middleware. Best of all, IFLs let you avoid buying additional, more expensive central processors for System z. SUSE now also offers the opportunity to buy subscriptions for multiple IFLs via a volume-discount pricing model.

Simpler, more efficient systems management

  • Administration tools you won't find anywhere elseSimplify systems management, from installing and configuring servers to ensuring security and increasing uptime. More ›
  • Superior package management with ZYppManaging package installations and dependencies can be an administrative nightmare. SUSE Linux Enterprise Server includes ZYpp, the fastest update stack available on any Linux enterprise distribution. SUSE has optimized ZYpp for performance and accuracy, and it is more feature-rich than tools such as YUM and Smart.
  • YaST/AutoYaST, WebYaSTYaST offers a user-friendly environment to install, configure and manage every aspect of your systems, both at install time and post-installation. AutoYaST enables automatic and remote systems configuration and large-scale deployments, while WebYaST offers all the functionality of YaST to users via a Web browser.
  • Starter SystemSUSE Linux Enterprise Starter System for System z is a pre-build installation server. It makes deploying a pilot system easy by eliminating the need for a separate system to host the installation files. Additionally, this tool ensures you won't need network connectivity outside the mainframe to install your Linux servers. More ›
  • Common code base advantageThe versions (and source code) of all core packages of the SUSE Linux Enterprise product family are the same, from the desktop to the mainframe. Our internal Build Service, unique to SUSE Linux Enterprise Server, automatically builds our Linux distributions for each architecture. The only human interaction occurs when the SUSE Linux Enterprise engineering team specifies the package selection, tool chain and target hardware architecture. As a result, the look and feel of all our SUSE Linux Enterprise products—no matter which architecture they run on—is consistent. This greatly simplifies systems administration for your IT staff. What's more, this common code base ensures the highest-quality code and improves supportability and preemptive code maintenance.

Advanced security management

  • AppArmorSUSE is renowned for its enterprise-class security applications.AppArmor®, an open source offering included with SUSE Linux Enterprise, is an effective, easy-to-use application security framework for Linux. It proactively protects the operating system and applications from external and internal threats and zero-day attacks. AppArmor includes default policies out of the box and lets you secure even the most complex applications with minimal time and resources.
  • Integration with other security productsSUSE offers connection with standard mainframe security through the Identity Manager Integration Module for Mainframes, which connects to RACF, ACF2 and Top Secret.

High availability

  • High availability includedUnlike other vendors, we include SUSE Linux Enterprise High Availability Extension with every subscription for SUSE Linux Enterprise Server for System z, making high availability affordable. This extension helps you maintain business continuity, protect data integrity and reduce unplanned downtime for your mission-critical workloads. More ›

Performance-boosting enhancements

  • New in Service Pack 2? SUSE has implemented more than 75 new features that enhance SUSE Linux Enterprise Server for System z with Service Pack 2. This update delivers significant advances in performance and I/O throughput, systems management, system diagnosis and problem resolution, as well as special features for the exploitation of the latest zEnterprise hardware. More ›
  • Optimized for the mainframe like no other Linux OSIn 2000, IBM and SUSE brought Linux to the mainframe. Today, SUSE Linux Enterprise Server for System z is the #1 choice for running Linux on IBM mainframes. More ›
  • Dynamic add/removeDynamic add/remove of central processing units (CPUs) and memory allows you to adjust the resources of a Linux guest under z/VM while it is running. This means a pool of CPUs can be allocated dynamically to a Linux guest and the CPUs can be used as needed. As a result, uptime and availability of the Linux guest and the applications increase.
  • Linux CPU node affinityThis feature improves system performance by scheduling processes to the optimal node where the CPU is associated, exploiting the z CPU node topology.
  • Vertical CPU managementWith this feature, you can switch between horizontal and vertical CPU polarization via a sysfs attribute. As a result, you achieve maximum performance from System z servers by maintaining awareness of each server's non-uniform memory access (NUMA) capabilities.
  • Large-page supportNow your systems can allocate process memory in chunks of 2 MB instead of 4 KB. As memory sizes increase, the necessary page tables consume enormous amounts of physical memory. Fewer larger pages can alleviate this problem, boosting performance through improved system throughput.
  • Next-generation crypto HW device driver exploitationHardware-based crypto acceleration enables more secure transactions per second. Functions such as CPU offload and increased security help reduce risk and maintenance costs.

New in SP3

  • Because system maintenance is an essential part of SUSE Linux Enterprise Server for System z, SUSE provides Service Packs (SPs) throughout the product lifecycle for all registered customers with valid subscriptions. A Service Pack is usually an original software update that consolidates periodic security and maintenance patches.
  • Where it is appropriate, where compatibility is ensured, and where Independent Software Vendor (ISV) certifications will not be affected, the Service Packs also incorporate product enhancements such as new hardware support.
  • This is very much the case with SUSE Linux Enterprise Server for System z 11 SP3, which delivers a host of enhanced new capabilities. Enhancements include advanced exploitation of the latest System z hardware releases, improved RAS capabilities, and increased performance, as well as a Technical Preview of KVM on System z. More ›

World-class support

  • World-class support from SUSELinux on the mainframe can be challenging, but SUSE is with you every step of the way. We have long been involved in integrating our solutions with those of other vendors, and our engineering team has collaborated with IBM on SUSE Enterprise Linux Server for System z for over a decade. As a result, our technical support personnel can tackle the toughest problems—at any scale and on any platform or combination of platforms.
