SUSE Linux Enterprise Server (SLES) is a Linux-based operating system developed by SUSE. It is designed for servers, mainframes, and workstations but can be installed on desktop computers for testing as well. New major versions are released at an interval of 3-4 years, while minor versions (called "Service Packs") are released about every 18 months. SUSE Linux Enterprise products, including SUSE Linux Enterprise Server, receive much more intense testing than the openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product.
SLES has been developed based on SUSE Linux by a small team led by Marcus Kraft and Bernhard Kaindl as principal developer who was supported by Joachim Schröder. It was first released on 31 October 2000 as a version for IBM S/390 mainframe machines. In December 2000, the first enterprise client (Telia) was made public. In April 2001, the first SLES for x86 was released.
SLES version 9 was released in August 2004. Service Pack 4 was released in December 2007. It is supported by the major hardware vendors—IBM, HP, Sun Microsystems, Dell, SGI, Lenovo, and Fujitsu Siemens Computers.
SUSE Linux Enterprise Server 10 was released in July 2006, and is also supported by the major hardware vendors. Service pack 4 was released in April 2011. SLES 10 shares a common codebase with SUSE Linux Enterprise Desktop 10—Novell's desktop distribution for business use—and other SUSE Linux Enterprise products.
SUSE Linux Enterprise Server 11 was released on March 24, 2009 and include Linux kernel 2.6.27, Oracle Cluster File System 2, support for the OpenAIS cluster communication protocol for server and storage clustering, and Mono 2.0. SLES 11 SP1 (released May 2010) rebased the kernel version to 2.6.32. In February 2012, SLES 11 SP2 was released, based on kernel version 3.0.10.
