SUSE Linux Enterprise Server helps you save money, deliver mission-critical data center services reliably and securely and get the most out of your mixed IT environment.
- Exploiting hardware RASEnhance your system reliability and reduce service costs by exploiting the RAS features of your hardware platform in ways only SUSE Linux Enterprise Server 12 can. SUSE Linux Enterprise Server 12 works with IBM POWER8, which offers RAS features like inventory collection (VPD), platform error reporting and handling, and responding to Emergency Power Off Warning (EPOW) events. The basic POWER platform-related tools and packages like ppc64-diag, servicelog and lsvpd are included in SUSE Linux Enterprise Server 12 to provide faster resolution.
- Full system rollbackThe Full System Rollback feature gives you better resiliency by allowing you to take snapshots of the system, including the kernel files, and roll back. Because the bootloader is now integrated into the rollback process, system administrators can boot from a snapshot, enhancing fault recovery and change tracking and comparison, and improving data safety.
- Control groupsSUSE Linux Enterprise Server features control groups for more fine-grained management of CPU, memory, storage and networking resources. Control groups let you assign specific hardware resources to applications, processes and threads. This precise control helps you optimize system performance, tune workload service response times and maximize uptime for your mission-critical workloads.
- Extensions for clusteringAchieve higher service availability by clustering servers together and removing single points of failure. SUSE Linux Enterprise High Availability Extension offers an industry-leading, mature high availability solution. Further enhance your business continuity by connecting data centers across unlimited distances with Geo Clustering for SUSE Linux Enterprise High Availability Extension.
- Kernel improvements and btrfs SUSE Linux Enterprise Server 12 ships with a modern 3.12 kernel, delivering enhanced RAS capabilities. You get improved scalability and data integrity with btrfs; a more resilient file system; faster snapshot capabilities including capture, restore and compare; and rollback for better change control and reduced service times.
- Security standards complianceSecurity impacts uptime. SUSE Linux Enterprise Server includes security features and functions to help to ward off malicious attacks and the shutdowns they cause. SUSE Linux Enterprise Server 12 is prepared for an upcoming Common Criteria Certification, and multiple security modules have been submitted to the National Institute for Standards and Technology (NIST) for a FIPS 140-2 validation. Among those modules are OpenSSL, OpenSSH client and server, Strongswan (IPSec-based VPNs) and the Kernel Crypto API. See the NIST list of modules in review.
- AppArmor ®This security framework protects your Linux OS and applications from external and internal threats and zero-day attacks. AppArmor comes with default policies for quick deployment so you can secure mission-critical applications quickly. Security profiles completely define what system resources individual programs can access and with what privileges. AppArmor also includes learning-based tools and advanced statistical analytics that simplify and accelerate the development of customized policies, even for the most complex applications. Additionally, with AppArmor you can change security policies dynamically, eliminating the need to reboot the system.
- True firewall protectionSUSE Linux Enterprise Server protects your network from internal and external attacks with a "stateful" firewall. The Linux netfilter framework lets you establish an effective firewall that separates networks from each other. With the help of iptables—a generic table structure for the definition of rule sets—you can precisely control which packets are allowed to pass through a particular network interface. Setting up this kind of packet filter is simple with SUSE firewal l2 and the corresponding YaST® administration module.
Improve Operation Efficiency
- Efficient package managementManaging package installations and resolving dependencies can be a nightmare. SUSE Linux Enterprise Server includes ZYpp, the fastest update stack available on any enterprise distribution. System updates that once took hours now take just minutes. Starting with SP2, SUSE Linux Enterprise Server supports a snapshot and rollback feature for package management and administrative tasks. This is accomplished by integrating the options of a btrfs file system (without the ZYpp stack) and the open source tool Snapper, resulting in simpler handling of btrfs snapshots.
- New YaST/AutoYaSTSave time and effort in managing local systems with a tool that’s easy-to-use and consistent in its user experience. In SUSE Linux Enterprise Server 12, the popular, user-friendly YaST gives you the capability to customize your system quickly during and after the installation. YaST is now written in Ruby so it’s more open and easily customized. AutoYaST extends the YaST functionalities to larger numbers of systems, letting you deploy server subsets or entire groups—even unattended.
- New installerSUSE Linux Enterprise Server 12 introduces a new installer that saves time with faster installation and fewer reboots in the workflow. Its Ruby scripts allow partners to embed SUSE Linux Enterprise Server into their solutions more smoothly.
- WickedWicked is a local network management tool that makes it easy to manage ever-more-complicated network configurations such as VLAN, virtualization, bridging, bonding and IPv6. Wicked, which originated in the "wicked" project, enables you to change configuration dynamically, thus providing network configuration as a service. Wicked allows you to import existing configuration files from older Linux operating system versions. You can perform standard configurations via the easy-to-use YaST interface.
- SUSE customer center (SCC) SUSE Customer Center is the new portal to centrally manage your SUSE subscriptions, access software updates and contact SUSE Customer Support. The user-friendly interface gives you a central view of all your SUSE subscriptions, allowing you to easily find the information you need. The streamlined registration flow gives you faster access to your patches and updates. And if you have any support requests or feedback, SUSE Customer Center is the place to go.
- The subscription management tool (SMT)The Subscription Management Tool is our proxy solution to help large organizations centrally receive patches and updates for their SUSE Linux Enterprise software. It provides our customers a way to easily migrate and gain much simpler and faster access to updates and patches. SMT is also the prescribed way for large organizations to gain the benefits of the SUSE Linux Enterprise Server Modules. Systems management functionality beyond a pure proxy is provided by SUSE Manager.
- IPv6The next-generation Internet Protocol version 6 specification (IPv6), the successor to IPv4, can provide far more address space for device connection. SUSE Linux Enterprise Server 12 natively supports IPv6, such as during installation. With IPv6 support, you can connect to next-generation network equipment.
- Interactive and unattended upgradesUsing this feature, system administrators can quickly and easily upgrade their SUSE Linux Enterprise Server operating systems, reducing downtime, lowering administrative costs and improving quality. In fact, SUSE Linux Enterprise supports (manual) major version upgrades for 10 years. With YaST, you can interactively prepare a suitable profile and then use AutoYaST to automatically upgrade groups of servers.
- ModulesModern innovation can outpace the traditional enterprise software delivery model. The modules available in SUSE Linux Enterprise Server 12 meet this need by providing faster integration with upstream updates. This design approach lets you balance the flexibility of the modules and stability of the infrastructure. More ›
