After a year and a half since the last update submitted to the release SUSE Linux Enterprise 11 SP 3 (Service Pack 3).
The distribution can be downloaded and used for free, but access to get updates and patches is limited to 60-day trial period. Release is available in assemblies for architecture x86 (32 – and 64-bit), Itanium, POWER and System z.
According to the company SUSE, SUSE Linux Enterprise 11 SP 3 is the industry’s first distribution which supports technology UEFI Secure Boot. In addition, it is noted that the hardware and software system based on SLES 11 SP 3 was successfully certified for compliance with the international safety standard EAL4 + Common Criteria and the American standard FIPS 140-2, defines the requirements for cryptographic modules.
Among the improvements has been added:
- Includes full support for booting in UEFI Secure Boot, based on the use of the loader Shim. In the UEFI Secure Boot is not only possible verification of the boot loader, but check downloaded in the future of the Linux kernel and performed at the kernel level modules, thus they can be checked using digital signature key-based SUSE. Thus given all the funds for the organization of the verified boot to protect the system from malicious third-party component substitution at boot time;
- Some new tools for migrating to SLES-intensive tasks running on the system RISC / UNIX. Improved virtualization and content migration of physical servers into virtual environments. The structure includes new versions of the hypervisor KVM 1.4 and Xen 4.2, adds the ability to carryover the PCI-devices in the guest environment using hypervisor Xen;
- Increased scalability when used on large systems. Supported by the server, with up to 4096 logical CPU and 16 terabytes of RAM;
- Added support for servers based on AMD Opteron processors 4000/6000, Intel Xeon E5 family-and fourth-generation processor Intel Core. Including those involved in these processors appeared in virtualization and power management mechanisms;
- Expanded support for storage and network adapters. The ability to use SAN-accelerator IBM zEnterprise System zEC12 Flash Express, 8/16 Gigabit Fiber channel adapters and 10/40 Gigabit Ethernet Adapters Ethernet. Added support for iSCSI Target (LIO). Improved support for FCoE (Fiber Channel over Ethernet). Updated stack OFED 1.5.4 (Open Fabrics Enterprise Distribution);
- Support for dynamic allocation of space in the repository (“thin provisioning”) for snapshots and logical partitions LVM;
- Support NFSv3 over IPv6 (NFSv4 work over IPv6 was available earlier). General improvements in support of the Protocol IPv6 – SLES passes completely texts USGv6 server software for compatibility with IPv6;
- Improved support for Btrfs, including added support for quotas and increased productivity;
- Support for the network installation using a secure HTTPS connection, in addition to the previously supported the setting mode for HTTP;
- Support for installation from USB Flash (iso-image of the installation DVD is decorated in a hybrid form, and it can be copied to the Flash);
- The integration framework that supports the protocol OpenSCAP SCAP (Security Content Automation Protocol) and a set of tools for automatic test systems for compliance with the safety requirements;
- Of the versions supplied packages can be noted: GCC 4.3.4, glibc 2.11.3, kernel Linux 3.0, perl 5.10, PHP 5.3 (discontinued support for PHP 5.2), python 2.6.8, ruby 1.8.7, MySQL 5.5, GNOME 2.28, KDE 4.3.5, OpenSSH 6.2.
Of the experimental features (Technology preview) noted:
- Support for nested virtual environments using KVM;
libguestFS to read and modify data in file systems, virtual machines;
- QEMU virtio-blk-data-plane;
- The ability to hot-add memory to a number of server systems;
- Support for iSNS (Internet Storage Naming Service);
- Mounting the root partition in read-only mode.
