Count on SUSE Linux Enterprise Server to handle mission-critical workloads and protect your applications, systems and data.

Today, your organization demands more from its IT resources, and more systems and applications are considered mission critical. Web services, e-commerce sites and securities-trading applications are just as critical as your online data processing, database and ERP systems. For your IT team, the pressure to ensure mission-critical services are continuously available while keeping risk in check is greater than ever.

We have designed SUSE Linux Enterprise Server to process all types of workloads, especially the mission-critical, while also providing the highest availability in its class. It supports productivity and reduces risk by helping your business to access critical systems, applications, networks and data continuously and securely.

Additionally, SUSE Linux Enterprise Server comes with advanced security capabilities that help you protect your systems from attacks, malicious applications and viruses.

Delivering the Best Uptime in Its Class

The most fundamental measurement of reliability is downtime (both planned and unplanned). In a recent survey conducted by the Information Technology Intelligence Corporation, respondents reported SUSE Linux Enterprise Server exhibited on average 17.4 minutes of unplanned downtime per server per year. Compare this with 35.4 minutes for Oracle Solaris, 67.2 minutes for Red Hat Enterprise Linux and 145.2 minutes for Windows Server 2008.

The same study found that the average time to patch a server (planned downtime) with SUSE Linux Enterprise Server was 15 minutes, versus 31 minutes for Solaris, 27 minutes for Red Hat Enterprise Linux and 32 minutes for Windows Server 2008. By minimizing both planned and unplanned downtime with SUSE Linux Enterprise Server, your business gains more access to the applications, systems and data it depends on to generate revenues and stay competitive.

Continuously Improving High Availability

For customers who require 99.999 percent reliability, we offer Linux clustering with SUSE Linux Enterprise High Availability Extension. This suite of open source technologies automates application failover and data recovery, and delivers all of the essential capabilities for the monitoring and messaging management of clustered resources. With SUSE Linux Enterprise High Availability Extension, you can maintain business continuity, protect data integrity and virtually eliminate unplanned downtime for your mission-critical Linux workloads. Best of all, it's more affordable than any competing third-party solution.

SUSE is committed to continuously integrating more reliability, availability and serviceability (RAS) capabilities into SUSE Linux Enterprise Server. Swap over network file system (NFS) helps protect your systems against application restarts and costly downtime. With control groups, you can assign specific hardware resources to applications, processes and threads. Such precise control helps maximize system performance, especially for mission-critical applications.

In addition, the latest operating system update, Service Pack 2 (SP2), includes features that boost RAS capabilities even more. CPU and memory hot plugging capabilities improve services availability. Support for RAID 6 and RAID 10 offers increased data redundancy, and enhanced MPIO hardware support expands multipath options. Also included in SP2 is support for btrfs, with snapshot and rollback for greater resilience.

Protecting Your Enterprise with Advanced Security

SUSE Linux Enterprise Server is not only perfect for processing mission-critical workloads and delivering business services. It also protects your intellectual property–the lifeblood of your business–with advanced, built-in security capabilities.

SUSE Linux Enterprise Server ships with AppArmor, an effective and easy-to-use security system. AppArmor proactively protects the operating system and applications from external or internal threats–even zero-day attacks–by enforcing secure behavior and preventing unknown application flaws from being exploited.

AppArmor security policies completely define what system resources individual applications can access, and with what privileges. Such oversight is critical today, as more people access your resources via the Internet and more workloads run in virtual environments and the cloud. AppArmor includes default policies so you can successfully deploy security policies for complex applications in just a few hours.

When it comes to enterprise Linux security, AppArmor is just the beginning. SUSE Linux Enterprise Server also provides a true firewall that protects your resources from internal and external attacks. This "stateful" firewall technology lets you separate networks and control which packets pass through any network interface.

SUSE Linux Enterprise Server also supports the Trusted Platform Module (TPM) standard for authenticating common hardware devices. Our comprehensive, enterprise-class security capabilities include certificate creation and management, VPN, encryption, authentication, access control lists and intrusion detection.
