SUSE Linux Enterprise Server
SUSE Linux Enterprise Server (SLES) is a Linux-based operating system developed by SUSE®. SLES is designed primarily for servers, mainframes and workstations. Major versions of SLES are released at an interval of 3 to 4 years, while minor versions called "Service Packs" are released about every 12 months.
A complete list of the kernel versions used with SLES versions can be found here.
