See what's new in SP2
Service Pack 2 gives you more than 75 new features specifically focused on enhancing SUSE Linux Enterprise Server for System z.
As mainframe Linux adoption expands and accelerates, so does the pace and scale of Linux development and innovation.
With SUSE Linux Enterprise Server for System z 11 SP2, you can easily implement the latest technical advances for Linux on your mainframe systems. Again, SUSE is first to take advantage of the Linux capabilities of IBM's new System z hardware. We have worked with IBM to make those advancements available in the mainstream Linux kernel.
In consequence, with Service Pack 2, SUSE has implemented more than 75 new features that enhance SUSE Linux Enterprise Server for System z. Many of them were created in direct response to customer requirements. Leading organizations from around the world participated in the beta program, and were deeply involved in testing and usability assessment. The advances and improvements in this release are a direct result of customer collaboration and SUSE's commitment to meeting our customer requirements.
This update delivers significant advances in performance and I/O throughput, systems management, system diagnosis and problem resolution, as well as special features for the exploitation of the latest zEnterprise hardware. To name just a few:
- Kernel 3.0: SUSE Linux Enterprise Server for System z 11 SP2 includes the Linux 3.0.x kernel. This allows for enablement of the most recent hardware, and provides massively improved I/O throughput and performance.
- Enhanced CPU node affinity support for z196: This feature allows the Linux kernel scheduler to optimize its decisions based on the z196 processor, cache and book topology, and provides for increased application workload density per system and much better performance.
- FICON DS8000 Solid State Drive support: Transparent to the DASD device driver, no change is needed to use solid state disks. A new flag in the device characteristics will show the administrator if a device is a solid state disk. Thus workloads can be placed on the storage which support best their I/O characteristics, random I/O is accelerated, and sequential I/O can be placed cost effectively.
- z196 exploitation via alternate GCC: This feature provides for performance improvement for applications through the exploitation of new z196 processor instructions and optimized alignment of code. This increases the application workload density per system, so less time and cycles are used for the same workload.
- FICON Dynamic PAV toleration: The DASD device driver tolerates dynamic Parallel Access Volume (PAV) changes for base PAV. PAV changes in the hardware configuration are detected and the mapping of base and alias devices in Linux is adjusted accordingly. This improves the flexibility and availability of SLES for System z, by allowing changes in the PAV infrastructure without the need to restart the system.
