COPERATIVE
CONSOLIDATION
The Credit Union System of Brazil saves millions of dollars
and gives back to nature by virtualizing on the mainframe
By Jim Utsler k Photography by Marcio Monteiro

S

erendipity is a funny thing.
You may start a project
with one goal in mind
and then, fortuitously, end up
with an equal or better benefit.
Companies that consolidate
servers to free up data center
space, for example, often end up
saving on energy-related bills.
The Credit Union System of
Brazil (Sicoob) experienced
something very similar to this.
Wanting to streamline its highly
heterogeneous computing
environment, it decided to migrate
as many workloads as possible to
the IBM mainframe using
z/VM*. This would result in a more
manageable IT environment that
would allow Sicoob to quickly
keep up with increasingly dynamic
market changes.
That was indeed a noble goal-
and was in fact achieved-but this
move to a largely single-system
computing environment resulted
in some unexpected benefits.
For example, the company is

now providing cloud services to its users, partners,
other companies and costumers, an advantage the
organization hadn't considered when it began its
consolidation efforts in 2007.
Additionally, Sicoob has realized substantial
cost savings when it comes to energy use, to the
tune of some $1.5 million a year. And for its efforts,
the Federation of Brazilian Banks recognized
the organization for its socially responsible
environmental contributions. "We knew that we
would save a lot, but we weren't expecting that
much," says Marcos Feitosa, Sicoob's IT manager.

Focusing on Business

Unlike traditional banks, Brasilia, Brazil-based
Sicoob is a cooperative system in nearly every sense
of the word. It's not a corporation. It's not on a
stock exchange. It's not in the business of simply
generating massive amounts of profits. Rather, its
focus is on its member users, or "associates," who
are the actual owners of Sicoob.
The roughly 2.5 million associates are serviced
by branches located throughout Brazil (the only
country in which Sicoob operates) and the 26,000some employees who work for the organization. The
associates go to the branches for savings and checking
accounts and credit and debit cards, as well as loans-
"every kind of service all banks provide," Paulo

Nassar, cloud team leader, Sicoob,
remarks. Profits from activities
such as these are used to improve
banking services and support the
development of the regions in
which branches are located.
Supporting these efforts are
two IBM zEnterprise* 196s
(z196), one of which is devoted
to business intelligence and is
running IBM software such as
SPSS*, Cognos* and InfoSphere*
DataStage*. The second z196
is used for production, with the
processing of the organization's
virtualized homegrown
application distributed between
that system and a newly installed
IBM zEnterprise EC12 (zEC12).
An IBM System z10* acts as a
disaster-recovery (DR) system,
while also performing some
parallel-processing functions.
Currently, Sicoob's core
banking application is used as
part of a Software-as-a-Service
(SaaS) computing model, with
each branch paying the larger
