SUSE® Linux Enterprise Server 11 Service Pack 1Scalability Today

• The only enterprise Linux operating system that helps customers

– Manage several workloads within one Linux instance in a lightweight manner by providing Kernel Resource Management with Control Groups

– Compute huge amounts of data in memory, e.g. in data- warehouse and ERP systems, by supporting 16TiB RAM(and beyond) on certified hardware

– Improve efficiency by leveraging HW support for power saving features due to the “tickles idle” Kernel, i.e. individual cores can be sent to sleep completely

SUSE® Linux Enterprise ServerScalability Future

• Container Technology (based on lxc) extends Kernel Resource Management and enables you to create lightweight virtualization-like separations for better load management and higher security (soft partitioning)

• With the increasing number of cores per system, improvements in power management and scheduling are key to control costs in physical and virtualized environments

• Local storage: maintain existing capabilities (e.g. XFS) and introduce btrfs as a supported solution, to improve manageability and give customers a maximum of flexibility

• Expand network filesystem capabilities (NFSv4.x/pNFS), to improve performance, reliability and security of filesystems across datacenter networks

SUSE® Linux Enterprise Server for System z 10 years on the Mainframe

The first deployments on Linux for the mainframe were file and print servers.

The first piece of software that became popular was Samba.

The first large commercial customer for SUSE Linux Enterprise Server for S/390 was Telia, the largest telecommunications company in Sweden.

Today, companies are running their mission-critical workloads on top of SUSE Linux Enterprise Server for System z.

Page 20: SUSE Linux Enterprise Server  for System z SP1

© Novell, Inc. All rights reserved.20

SUSE® Linux Enterprise Server for System z 11New Features in GA Version

Dynamic add/remove of CPU and memory: resources of a Linux guest under z/VM can be adjusted while running. A pool of CPUs are dynamically given to a Linux guest and used as needed

Vertical CPU management: helps get the most performance out of System z10 servers by being aware of the server's NUMA characteristics

Linux CPU Node Affinity: improves performance by scheduling processes to the optimal node where the CPU is associated, exploiting the new System z10 CPU node topology

Enhanced HiperSocket support: Additional Layer 2 support for IPV4 and support for IPV6

Modularization of qdio and thin interrupts: Make the thininterrupt layer independent from qdio and improve the codelayering in the qdio module. This provides for additional performance enhancements.
