SUSE Linux Enterprise Server

New and improved enterprise-class RAS features in SUSE® Linux Enterprise Server help you get the most from your systems and reduce expensive downtime.

Swap over NFS

SUSE Linux Enterprise Server supports swap over NFS. This allows you to use network file system (NFS) over Internet protocols (IP) to use remote storage for local server needs. Once you are no longer restricted to local storage for swap space, you can cut costs dramatically. You can use less costly diskless servers, and simplify server administration—thus reducing acquisition, implementation, administration, and management costs. By using swap over NFS, you can protect your systems against application restarts and expensive downtime.

Control Groups

SUSE Linux Enterprise Server also comes with several kernel-level features and power management capabilities that let you get the maximum performance from your systems. SUSE Linux Enterprise Server comes with control groups for more fine-grained management of CPU, memory, storage and networking resources. Control groups allow you to assign specific hardware resources to applications, processes and threads. This provides you with more granular control of resources and prioritized processing. The result is greater performance for your critical workloads and processes.

Kernel Improvements

SUSE Linux Enterprise Server includes scheduler enhancements that let you optimize the platform for specific workloads. Asynchronous and multipath I/O capabilities reduce overall disk read/write times, and enable the accessing of storage devices through multiple channels. This yields better load balancing and improved performance.
