IBM Systems Magazine, Mainframe - July/August 2014 - 33

"If you have a mission-critical workload with a lot of work to
do, the last place you should put it is on an x86 server. It
belongs on a secure, highly reliable, high-utilization server."
-Joe Clabby, president, Clabby Analytics

servers feature functional recovery
routines for every major routine
in the system, for example,
allowing them to rapidly refresh if
a problem occurs. An automated
restart manager in the z/OS*
allows the system to reboot
failing software components. The
operating system also performs
predictive failure analysis, over
time learning to anticipate
problems and report them.

More for Less
It's hard to argue with the
performance advantages. The
mainframe offers big value for the
money, featuring virtualization
that can deliver nearly 100
percent utilization for sustained
periods of time. Virtualized x86
networks are an improvement over
computing silos scattered around
the enterprise, but their utilization
rates might only reach 60 percent-
nowhere near the mainframe level.
That means with x86 you're
paying for computing resources
that will sit idle much of the time
and your operations could suffer
because you can't effectively access
the resources you have. Next thing
you know, you're buying more
systems to do the work. Which
brings us to a little-appreciated
fact: for heavy I/O workloads
like those found in transaction
processing, a System z solution
can cost less than x86 solutions.
Sure, the capital outlay for
your x86 boxes is lower. You
might get your hardware for a few

hundred thousand dollars versus
$1 million for a mainframe,
which certainly appears cheaper
at face value. It's important to
keep in mind, however, that the
cost of operations dwarfs the cost
of acquisition. All of those x86
boxes doing your processing have
multiple cores, and each core
requires its own software license.
Compare this to a System z server
with a single core, and suddenly
that x86 server farm doesn't
sound so cheap anymore.
According to Clabby's analysis,
implementing the same heavy I/O
workloads on an x86 platform
would cost $1 million more than a
mainframe solution. Add to this the
staff hours required to update all
of those cores, not to mention the
cost of power, cooling, cabling and
space. And since this is a discussion
of risk management, it is important
to remember that more cores means
more security vulnerabilities and
more opportunity for failure.
In contrast, a System z solution
consists of one box to commission,
power and maintain; one core to
license; and one core to protect.
Best of all, with automatedmanagement tools and predictive

utilization

analytics, mainframes are getting
easier to manage every year.
"It's a great architecture, with
industry-leading security, a huge
communication subsystem, and
the fastest processor, which makes
it best in the industry at handling
heavy I/O workloads," Clabby says.
"The problem is that x86 people
don't understand that so they
keep buying more and more x86
machines and software in order to
secure their environments."
It's important to note that x86
boxes do have important roles to
play in infrastructure-oriented
applications like HTML serving and
firewalls, file/print and Web-facing
workloads. They are not, however,
appropriate for I/O intensive,
essential workloads.
Organizations with these types of
heavy I/O workloads can continue
to buy x86 servers. They can
try to augment them by adding
communications switches and
hardware or software solutions
designed to create a distributed
computing environment with
failover, backup and recovery
capabilities. Ultimately, however,
they will wind up paying more for
these capabilities while at the same
time risking failures, data breaches
and underperformance.
The key is to choose the right
tool for the job. "If you have a
mission-critical workload with a
lot of work to do, the last place
you should put it is on an x86
server," Clabby says. "It belongs
on a secure, highly reliable,
high-utilization server. That's
why you choose a mainframe.
If people don't take the time to
understand that, they're going
to end up spending a lot more
money to process the same work
and wasting corporate funds while
doing it."
