Please find more security certifications and features here.
  • AppArmorThis 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 SuSEfirewall2 and the corresponding YaST® administration module.
  • Trusted Platform Module (TPM) supportSUSE Linux Enterprise Server includes support for the TPM standard, which facilitates the authentication of hardware devices like laptops or desktops in, for example, corporate network environments
  • Comprehensive and precise security administrationSUSE Linux Enterprise Server exposes the latest hardware security features like the Advanced Encryption Standard (AES) instruction set. Applications and hardware that leverage AES operate more securely as a result. Other capabilities include certificate creation and management, VPN, encryption, authentication, access control lists, intrusion detection and more.

    • IBM POWER7
    • IBM POWER7+
  • CPU and RAM limitsSUSE Linux Enterprise 11 can support up to 1024 logical CPUs on ppc64. The theoretical limit of RAM support of SUSE Linux Enterprise 11 is 1 PiB, The practical limit, which is more important to customers, is 512 GiB on certified hardware.
  • PCI Express Solid State Drive (SSD)PCI Express SSD is a fast throughput and low latency interface technology. It supports connecting the SSD through the PCI Express interface to the server. This feature will boost the performance of local I/O and caching of your workloads, for example, databases. What's more, you can fine-tune applications that are sensitive to hierarchical storage layout at a more granular level.
  • Open Fabrics Enterprise Distribution (OFED)OFED is the software stack developed by the OpenFabrics Alliance which uses remote direct memory access switched fabric technologies for server and storage connectivity. OFED provides high CPU efficiency, lower energy consumption and reduced rack-space requirements for cost savings. SUSE Linux Enterprise 11 Service Pack 3 support OFED 1.5.4.
  • Data Center Bridging (DCB)DCB refers to a set of enhancements to Ethernet local area networks for use in data center environments. DCB allows you to build an Ethernet-based converged networking for both storage and data networking for lower total cost of ownership (TCO) and simpler management.
  • Logical Volume Manager (LVM) thin-provisioningThin provisioning is a way to place virtual devices on a data volume that can share data, grow with use and allow for snapshots of snapshots without degradation. This functionality is enhanced in Service Pack 3. Thin provisioning gives you physical storage over subscription and lets you optimally utilize available storage in your shared storage environment on the Volume Management layer.
  • iSCSI Target (LIO)The iSCSI Target (LIO) implements a generic SCSI target that provides remote access to most data storage device types over all prevalent storage fabrics and protocols. iSCSI target (LIO) support increases speed and synchronizes the target for iSCSI and FCoE together, using just one stack to improve throughput and performance.
  • IPv6The next-generation Internet Protocol version 6 specification (IPv6) is the successor to Internet Protocol version 4 (IPv4). Kernel subsystems and other system services, including NFSv3, AutoFS, UEFI 2.3.1, and Python-Ethtool, have been upgraded to support IPv6.
  • Support for high-speed interconnectsOpen Fabrics Enterprise Distribution (OFED) 1.5.4 support enables affordable, high-speed, remote direct memory access (RDMA) capable fabrics and unified interconnects based on InfiniBand and 40 Gigabit Ethernet. Support for Fiber Channel over Ethernet (FCoE) allows existing fiber channel storage to be accessed using an Ethernet adapter. Data Center Bridging (DCB) enhancements allow network traffic with differing requirements to operate and co-exist on Ethernet networks.

Simplified Administration, Development and Systems Management

  • 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.
  • YaST/AutoYaST/WebYaSTYaST is a user-friendly environment for installing and configuring Linux systems. Predefined patterns simplify setup and deployment. AutoYaST extends this functionality to larger numbers, letting you deploy server subsets or entire groups—even unattended. WebYaST offers the functionality of YaST via a web browser.
