1.z/OS V1.7 support on the z10 BC™ requires the Lifecycle Extension for z/OS V1.7, 5637-A01. The Lifecycle Extension for z/OS R1.7 + zIIP Web Deliverable required for z10 to enable HiperDispatch on z10 (does not require a zIIP). z/OS V1.7 support was withdrawn September 30, 2008. The Lifecycle Extension for z/OS V1.7 (5637-A01) makes fee-based cor- rective service for z/OS V1.7 available through September 2009. With this Lifecycle Extension, z/OS V1.7 supports the z10 BC server. Certain functions and features of the z10 BC server require later releases of z/OS. For a complete list of software support, see the PSP buckets and the Software Requirements section of the System z10 BC announcement letter, dated October 21, 2008.

2.Compatibility Support for listed releases. Compatibility support allows OS to IPL and operate on z10 BC

3.Requires Compatibility Support which allows z/VM to IPL and operate on the z10 providing IBM System z9® functionality for the base OS and Guests. *z/VM supports 31-bit and 64-bit guests

4.z/VSE V3 operates in 31-bit mode only. It does not implement z/ Architecture, and specifically does not implement 64-bit mode capabili- ties. z/VSE is designed to exploit select features of IBM System z10, System z9, and IBM eServer™ zSeries® hardware.

5.z/VSE V4 is designed to exploit 64-bit real memory addressing, but will not support 64-bit virtual memory addressing

Note: Refer to the z/OS, z/VM, z/VSE subsets of the 2098DEVICE Preventive Planning (PSP) bucket prior to installing a z10 BC

Everyday the IT system needs to be available to users

–customers that need access to the company Web site, line of business personnel that need access to the system, application development that is constantly keeping the environment current, and the IT staff that is operating and maintaining the environment. If applications are not consis- tently available, the business can suffer.

The z10 EC continues our commitment to deliver improve- ments in hardware Reliability, Availability and Serviceability (RAS) with every new System z server. They include micro- code driver enhancements, dynamic segment sparing for memory as well as the fi xed HSA. The z10 EC is a server that can help keep applications up and running in the event of planned or unplanned disruptions to the system.

IBM System z servers stand alone against competition and have stood the test of time with our business resiliency solutions. Our coupling solutions with Parallel Sysplex tech- nology allows for greater scalability and availability. The Infi niBand Coupling Links on the z10 EC provides a high speed solution to the 10 meter limitation of ICB-4 since they will be available in lengths up to 150 meters.

What the z10 EC provides over its predecessors are improvements in the processor granularity offerings, more options for specialty engines, security enhancements, additional high availability characteristics, Concurrent Driver Upgrade (CDU) improvements, enhanced network- ing and on demand offerings. The z10 EC provides our IBM customers an option for continued growth, continuity, and upgradeability.

The IBM System z10 EC builds upon the structure introduced on the IBM System z9 EC – scalability and z/Architecture. The System z10 EC expands upon a key attribute of the platform – availability – to help ensure a resilient infrastructure designed to satisfy the demands
