ability to have your data or log
data and metafiles stored in a
clustered file system that are
accessible from multiple nodes.
So, for example, a client is
running an application server
(like WebSphere* Application
Server) that happens to go down,
and all of the logs that were
written by that application server
can actually be accessed from
another node, another application
server on another node that
reaches into the same file system
that is being shared and you
have all of your high-availability
capabilities. There's no need to
restart that system.
Q
A
Part of the z13 announcement
was the statement
of direction for KVM. How does
KVM benefit clients?
We've had great success
bringing Linux to z Systems.
We are investing in an open
hypervisor and open management
tooling to build on that success.
KVM is an open-source industrystandard
hypervisor that is well
known in the Linux environment.
It is supported on x86 platforms
and the Power* platform and
we intend to deliver that on the
z Systems platform as well. It
gives clients flexibility and choice.
KVM allows clients who don't
necessarily have z System skills
today or may not have z/VM*
skills today to easily deploy a
hypervisor and Linux VMs on
that hypervisor. Often these
clients will have KVM skills that
they are leveraging on other
platforms. The addition of KVM
on z Systems allows them to
use tools and the governance
models for which they have
existing skills already in their
environments. KVM also provides
a large open-source community.
Q
Is the addition of KVM
something clients
requested?
6 // MAY 2015 Linux on z Systems
A
Yes, a number of our clients
have asked for this because
they wanted that choice and
that flexibility. They have a skill
base built around KVM already
and they want to be able to
leverage that on z. It also brings
the investment that the opensource
community is developing
on top of KVM and around KVM.
IBM will be able to leverage that
large investment and bring that
to our clients. So it really does
attract new clients that may have
not been interested in coming to
the platform but now with this
open-source standards KVM,
they will be attracted to the
platform. IBM will also continue
to build capabilities around the
standard KVM that provide more
enterprise capabilities that our
customers expect.
Our clients are looking to
cloud delivery mechanisms,
whether it is a private cloud
within their enterprise
delivering to their internal
clients or if it is leveraging a
public cloud to augment their
on-premise enterprise private
cloud. We also see a number of
our clients starting to provide
services based on their internal
capabilities, including hosting,
infrastructure as a service,
platform as a service and
especially software as a service.
We also see interest from
service providers in the
mainframe. Much of that is due
to the higher-level quality of
service that they would be able
to leverage to provide a superior
experience to their end users.
Part of it is the cost efficiencies
of aggregating workload onto
a large z System and part of it
is the ability to differentiate
from some of the cloud service
providers that provide a
commodity experience. This is
where KVM with its open-source
standardized hypervisor can
help because these companies
-Bryan foley, business line manager for Linux on z Systems
already have experience using
KVM to provide virtual machines
to their end users.
Q
A
What does the KVM
announcement mean for
z/VM users?
We have honed z/VM, and
its virtualization capabilities
have been optimized for the
mainframe for decades-it is a
best-of-breed hypervisor. IBM will
continue to invest in it and make
improvements as we go forward.
Many of our largest clients rely on
z/VM as their virtualization layer
for Linux for their mission-critical
workloads. These clients rely on it
for its optimization characteristics.
IBM has recently increased
that investment to deliver more
innovation and to meet the needs
of our clients as they want more
and more out of the hypervisor
layer. For example, clients wanted
to be able to host more virtual
