TECH SHOWCASE

From Novelty
to Powerhouse
How Linux on System z has become a go-to
solution for businesses
By Shirley S. Savage

C

hances are you're
engaging with Linux*
on a daily basis without
even realizing it. The OS plays a
role in many aspects of your dayto-day life, from ATM transactions
to your home office printer to Web
services to your Android phone.
In just more than two decades,
Linux has become the most
sought-after open-source OS
used by companies worldwide.
IBM continues to be a proponent
of Linux, a role it adopted in
1999 when it first announced
Linux would be available on all
platforms, including System z*
servers. Since then, the OS has
matured from a penguin-logoed
novelty to a powerhouse system
used by enterprises as well as small

and medium businesses. "So who's
using Linux? You are," says Bill
Reeder, worldwide IT optimization
sales leader, System z.
Much of the interest in Linux on
System z is now being driven by
cloud, virtualization and server
consolidation, says Bryan Foley,
program director, System z Strategy
and Linux for System z Business
Line Manager. "The ability to
consolidate several individual
servers onto a single platform is a
first step, and customers recognize
that Linux on System z is a great
place to do that."
Organizations can realize
cost, security and performance
benefits by consolidating to
a single platform. One IBM
customer consolidated more than

200 x86 processors down to 17
processors on the mainframe,
saving on licensing, operational
and personnel costs. Another
company found consolidating
with Linux on System z
eliminated many of its technical
issues, according to Foley.

Smart Move
Companies are choosing to
run Linux on System z to take
advantage of the mainframe's
robustness, reliability, security
and disaster recovery capabilities.
The platform is designed
to maintain transactional
throughput up to 100 percent of
CPU utilization because I/O to
disk and network are offloaded
from the transactional CPU, which
