z/VSE
z/VSE 4.1, the latest advance in the ongoing evolution of
VSE, is designed to help address needs of VSE clients
with growing core VSE workloads and/or those who wish
to exploit Linux on System z for new, Web-based business
solutions and infrastructure simplifi cation.
z/VSE 4.1 is designed to support:
• z/Architecture mode only
• 64-bit real addressing and up to 8 GB of processor
storage
• System z encryption technology including CPACF, con-
fi gurable Crypto Express2, and TS1120 encrypting tape
• Midrange Workload License Charge (MWLC) pricing,
including full-capacity and sub-capacity options.
IBM has previewed z/VSE 4.2. When available, z/VSE 4.2
is designed help address the needs of VSE clients with
growing core VSE workloads. z/VSE V4.2 is designed to
support:
• More than 255 VSE tasks to help clients grow their CICS

• IBM System Storage TS7740 Virtualization Engine
Release 1.3
z/VSE V4.2 plans to continue the focus on hybrid solu-
tions exploiting z/VSE and Linux on System z, service-ori-
ented architecture (SOA), and security. It is the preferred
replacement for z/VSE V4.1, z/VSE V3, or VSE/ESA. It is
designed to protect and leverage existing VSE information
assets.
z/TPF
z/TPF is a 64-bit operating system that allows you to move
legacy applications into an open development environ-
ment, leveraging large scale memory spaces for increased
speed, diagnostics and functionality. The open develop-
ment environment allows access to commodity skills and
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 application 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 EC supports the following Linux on
System z distributions (most recent service levels):
• Novell SUSE SLES 9
• Novell SUSE SLES 10
• Red Hat RHEL 4
