IBM Z10 BC manual Linux on System z, Operating System ESA/390

enhanced access to open code libraries, both of which can be used to lower development costs. Large memory spaces can be used to increase both system and appli- cation effi ciency as I/Os or memory management can be eliminated.

z/TPF is designed to support:

•64-bit mode

•Linux development environment (GCC and HLASM for Linux)

•32 processors/cluster

•Up to 84* engines/processor

•40,000 modules

•Workload License Charge

Linux on System z

The System z10 BC supports the following Linux on System z distributions (most recent service levels):

•Novell SUSE SLES 9

•Novell SUSE SLES 10

•Red Hat RHEL 4

•Red Hat RHEL 5

Operating System	ESA/390	z/Architecture

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 z/OS V1.7 support was withdrawn September 30, 2008.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 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 System 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 31-bit mode only. It does not implement z/Architecture, and specifi cally does not implement 64-bit mode capabilities. z/VSE is designed to exploit select features of 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.
