IBM System z10 EC Reference Manual page 8

IBM has previewed z/VSE 4.2. When available, z/VSE 4.2 is
designed to support up to 32 GB of processor storage and
more than 255 VSE tasks.
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 appli-
cation efficiency as I/Os or memory management can be
eliminated.
z/TPF is designed to support:
• Linux development environment (GCC and HLASM for
Linux)
• 32 processors/cluster
• Up to 84* engines/processor
• 40,000 modules
IBM System z10 EC
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 fixed 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 solu-
tions. Our coupling solutions with Parallel Sysplex technol-
ogy allows for greater scalability and availability. The new
InfiniBand Coupling Links (planned to be available 2nd
®
quarter 2008*) on the z10 EC are rated a 6 Gbps and pro-
vides 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, newer security
enhancements, additional high availability characteristics,
Concurrent Driver Upgrade (CDU) improvements,
enhanced networking and on demand offerings. The
z10 EC provides our IBM customers an option for contin-
ued growth, continuity, and upgradeability.
The IBM System z10 EC builds upon the structure intro-
duced on the IBM System z9 EC (formerly z9-109) – scal-
ability 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 of your business. With the potential for increased
performance and capacity, you have an opportunity to
continue to consolidate diverse applications on a single
