IBM Systems Magazine, Mainframe - March/April 2017 - 30


"If a client has a high-risk workload
that needs to be in a secure
environment and handle future
growth, we can offer the capabilities
of the mainframe with traditional and
open-source workloads."
-Steffen Thoss, offering manager, z Systems virtualization and Linux

says Steffen Thoss, offering
manager, z Systems virtualization
and Linux, IBM.
SUSE currently offers z/VM*
support and will soon add KVM
support, Thoss says. SUSE's
offerings include OpenStack
enablement via the SUSE
OpenStack Cloud product. Meanwhile, Canonical supports an
OpenStack solution with its own
version of KVM. IBM and Red Hat
are discussing enabling cloud
options for z Systems.
Container technology from
Docker, Kubernetes, Apache
Mesos and Canonical's Ubuntu
LXD/LXC support the cloud
environment, says Marcel Mitran,
IBM Distinguished Engineer, CTO,
IBM LinuxONE*. Deployment and
management tools-such as Chef,
Puppet, Salt Stack and Ansible-
and application management and
orchestration tools-including API
Connect and Juju-are available
to help clients offer as-a-service
environments.
Cloud calls for integrating
all of the platforms running in
your data center, which makes
using open-source software a
natural choice. IBM works with
its distributors to enable Linux on
z Systems clients to use the same
open-source software that runs on
x86. By doing so, "we are aligning
with the needs of our client," says
Gerald Hosch, marketing, Linux
z Systems, IBM.

The Co-Location
Advantage
Client needs are also well-served
by running Linux with z/OS or
z/TPF on the same platform, as
this prevents server sprawl in
the data center and streamlines
infrastructure.
Many clients host their most
mission-critical applications
on the mainframe because
of its reliability, security and
availability. They appreciate
the economy of scale the
z Systems platform provides.
Hundreds of applications can
run on the same server, which
improves operational efficiency,
density and utilization, Adlung
says. Co-location minimizes data
crawl by placing the data close
to the applications to yield high
performance and low-latency
networking.
Co-location also adds
flexibility to the mix. Adlung
notes one midsized z Systems
client that added Linux to
support z/OS. It reaped the
benefit of co-locating Linux
on IBM z* as well as scaling
easily to fit demand. The client
was so pleased with the Linux
installation that it added
workloads independent of
z/OS. Now its Linux footprint
is larger than that of z/OS. "It
is really a blueprint for the
utilization of both z/OS and
Linux," he says.

Improved Efficiency

R

IBM works
closely with its

3
Linux distribution
partners to
serve client
requirements for
cloud and related
technologies

Running Linux on z Systems
gives clients all of the benefits of
the mainframe platform, which
enables many VMs to run at
the same time, Thoss explains.
Clients see high response times
and throughput when running
traditional and open-source
workloads in parallel because
z Systems uses resources such as
memory and CPU more efficiently
than other platforms. A client
can run data of record, such
as DB2* on z/OS, and connect
it to workloads in the Linux
environment, which benefit from
the z Systems platform's security
and tooling for both environments.
Linux on IBM z also helps with
consolidation. Thoss points to a
banking client that experienced
a growth surge that resulted in
a new bank branch opening
daily. The client realized that
having a separate x86 server for
each branch was making the IT
environment unmanageable. It
switched to Linux on z Systems
to gain more control and better
management of its IT. This also
resulted in a more cost-efficient
system and the ability to grow in
the future.

Preparing for
Next-Gen Applications
Some traditional, risk-averse
clients want to maintain a secure,
protected platform, and IBM
