"By not moving data off the mainframe, you're actually
preserving security and governance of the data. When
you're not making, moving and sharing copies of it, you
can prevent breaches or compromised data."
-Nick Sardino, program director, IBM z Systems Offering Management

out to the cloud, as it's relatively
easy to use and doesn't require
huge capital outlays. Others
interested in machine learning,
continuous intelligence and
cognitive processing, however,
are more interested in an on-site
platform that will perform data
analysis faster, providing a more
robust competitive advantage.
"Last year, IBM announced
a cloud-based IBM Watson*
Machine Learning environment,
and people were rightly very

excited about it. There are
definitely benefits to it," Sardino
notes. "But others have expressed
an interest in having an analytics
platform that sits right next to
their data."
And that's the z Systems
platform and IBM z* Analytics,
along with a number of
related machine learning and
analytics tools. The mainframe
is able to perform complex
machine learning and cognitive
processing across multiple

I/O Improvements for Machine Learning
On the IBM z13* system, data proximity has been bumped up across all cache
levels. For example, L1 and L2 cache is per core and there are eight cores on
a central processor (CP) chip. Technical specs include:
*
*
*
*
*

L1 cache/core
96 KB I-cache
128 KB D-cache
L2 cache/core
2M+2 MB eDRAM split private L2 cache

L3 cache is per CP chip, and there are six CP chips in a drawer.
Its specs include:
*
*

On-chip 64 MB eDRAM L3 Cache
Shared by all cores

L4 cache is per system controller (SC) chip, and there are two SC chips in
a drawer. Specs include:
*
*
*

eDRAM Shared L4 Cache
480 MB per SC chip (Non-inclusive)-224 MB L3 NIC Directory
2SCs = 960MB L4 per z13 drawer

data sources more quickly and
efficiently than other platforms.
"Some of the more
sophisticated analytical
operations benefit from
z Systems processor technology
including Java* enhancements
that benefit the analytics engine,
the IBM z/OS* Platform for
Apache Spark, as well as the
large amount of supported
memory, increased I/O
bandwidth and a very rich
caching structure," Sardino says.
"This is especially true of the
IBM z13*."
And unlike cloud resources,
an on-premises mainframe
essentially butts against critical
data-storage resources. This helps
allay concerns some may have
regarding machine learning in the
cloud, including how to transfer
data, how to ensure cloud-based
data is current, how secure the
data is and how to avoid potential
network latency issues that may
hamper model retraining.
"By not moving data off the
mainframe, you're actually
preserving security and
governance of the data. When
you're not making, moving
and sharing copies of it,
you can prevent breaches or
compromised data," Sardino
says. "It's also about the value
of the data on the mainframe,
the value of running analytics
on that data and the proximity
to up-to-the-minute
transactional data.
