The Right Fit?

By Joe Temple

M

atching workloads to IBM System z* requires
careful consideration. This article outlines the
process from a high-level viewpoint but one that’s
still technically credible and consistent. While much of this
discussion is applicable to other platforms, our focus will be
on the mainframe perspective.

The IBM System z platform is
a computer, which means it can be
programmed. Given code, it can run
any workload. In fact, any computer can
run any workload as long as the code to
perform the work is available. Thus, the
initial three questions to ask about an
existing workload are:

1

Will the code run on System z?
If the answer is yes, the workload is
a candidate to run on the mainframe.
It’s also important to note that
the workload is a candidate to run
anywhere the code is available.
Therefore, code availability for the
platform is a necessary consideration
but not sufficient to determine
workload fit.

If we put the workload on
System z, will it run well?
Traditionally, workloads with high
I/O content were a good match
for System z. This is still true, but
large enterprise UNIX* machines—
particularly IBM Power Systems*
servers—have considerable I/O
capability, including the capability to
virtualize the I/O using processor cores
and internal networking. Accordingly, a
high I/O rate doesn’t necessarily make a
workload a slam dunk for System z, but
it does point to a good candidate.

How much memory
and storage does the
application require?
During the client-server boom of the
’90s, many applications were written

Running highly stacked
workloads on System z
can greatly reduce cost
per unit of work
