Accelerating Application
Development and
Analytics
Another difference involves
the multiplatform interpretive
language Java*. It runs faster
on the z14 ZR1 than competing
platforms by removing some
critical Java development pain
points. Large Java applications
periodically manage memory heap
sizes in a process called garbage
collection, which can impact
application responsiveness.
To counter this, IBM built into
the hardware and the software a
function called pause-less garbage
collection. As a result, very large
Java programs running on the z14
ZR1 won't experience the same
"hiccups they do running on every
other system," Mauri notes. In
fact, new and existing secure Java
workload performance has been
improved by up to 30 percent,
latency by 50 percent and overall
Java on IBM Z outperforms Java on
x86 by 50 percent.
In addition, many z14
ZR1 features help accelerate
advanced analytics, including
technology such as the IBM Db2*
Analytics Accelerator for IBM
z/OS to support the IBM Db2
database. This approach allows
for simultaneous support for
traditional online transaction
processing and advanced
analytics workloads.
IBM has also delivered support
for machine learning and artificial
intelligence technology natively
on IBM Z with its introduction
of IBM Open Data Analytics for
z/OS, which includes Python,
Anaconda and Apache Spark. This
is in an effort to build out a full
data-analytics environment and
open it up to existing and new
tools that can take advantage of
IBM Z data where it resides, and
in real time.
"We've opened up IBM Z to all
the new types of data-science

tools that are out there, making IBM Machine
Learning for z/OS the most advanced machine
learning system in the world. We're building on
our heritage, with an industrial-strength database
that scales and performs like no other and allowing
users to access their data via open source or other
companies' analytics tools," Mauri says.
In the past, data may have been moved to a
specialized analytics environment to reduce
latency issues on production systems. By adding
new instruction sets and delivering additional
performance improvements to the z14 ZR1, this type
of analytics can be performed on this system, helping
improve the speed of insights without introducing
risk associated with the movement of data.
"We start at the bottom of the stack, accelerating
the core. Then we move up the stack to an opensource platform and open-source tooling that are
common and used by today's data scientists,"
Tarquinio notes. "They can now get onto the IBM
Z platform and access data just like they would
on any dedicated analytics platform. The data is
protected, thanks to the ability to take advantage of
our IBM Z security. The data remains on the source
database so data scientists have the analytics tools
of their choice to derive value from their data as
quickly as possible."
Also accelerating z14 ZR1 performance is
improved I/O speed. IBM zHyperLink Express is a
new direct-connect short-distance link designed to
deliver low-latency connectivity between z14 and
FICON storage systems. It also improves application
response time, cutting I/O-sensitive workload
response time by up to 50 percent without requiring
application changes.

19-Inch Rack Provides
Space for Storage
Clients looking to customize their IBM Z even
more can utilize unused space in the new 19-inch
frame, by placing other data center components
in the frame. This allows storage vendors to put a
storage subsystem in the rack along with the server
and basically have a data center in a single frame,
for example. This new rack-space friendly design
allows them to put a cost-effective rack footprint in
these data centers. Clients looking to grow into new
markets could use this customization as a way to
have enterprise infrastructure in a smaller footprint.
Working with their partners in IBM Storage, this
announcement includes a statement of direction
for a rack-mounted all flash IBM Storage offering,
that will fit into the unused space in an IBM z14
ZR1. "Taking advantage of the continuing reduction

in size and increasing power
of microelectronics, we've now
packaged this so you can put a
full z14 ZR1 and a flash array in a
single cost-savings frame," Mauri
says. "We've had clients ask for
this, and we think many of them,
as well as business partners, are
going to be excited about this."
When you combine the power of
IBM Z and the optimization with
storage, you begin to get a feel of
how the IBM Z team approaches
system design and development.

A Technological
Orchestra
As clients move toward a mixture
of infrastructure, between
on-premises and cloud, their needs
may change, but the IBM Z platform
can be relied on to meet business
demands. It's fast, flexible,
scalable and secure, and promotes
advanced analytics and machine
learning. Its services can stay
within the confines of a company's
walls or extend to the cloud. The
choice is the user's.
And make no mistake about
it, these systems are built for
today's advanced workloads
and ever-changing data
requirements. They're new, fresh
and ready for another generation
of users and workloads.
"From the silicon up, we
build our own systems-the CPU
architecture, the microprocessor
architecture and implementation,
the I/O subsystem, the cache
hierarchy, the microcode, the
virtualization layers. We innovate
throughout the stack, more so
than anyone else in the industry,"
Mauri says. "As a result, we can
design and tune everything in the
stack to work in harmony, like
an orchestra. That's one of our
advantages."
Jim Utsler, senior writer for
IBM Systems Magazine, has been covering technology for more than 20 years.
