"If we hadn't
invested so heavily
in virtualization, we
couldn't have been
able to capture ...
additional benefit."
-Marcos Feitosa, IT manager, Sicoob

cooperative to use the software.
Payments are based on the
proportionate size and volume
of the branches, with smaller
ones paying less and larger
ones paying more. If, however,
branches prefer to manage their
own IT departments, they're more
than welcome to, whether they
purchase their equipment from
IBM or other sources.
But as Feitosa notes, "While
they're essentially independent
entities, it's probably more
efficient for them if they don't
purchase their own IT assets. We
offer everything they need, and
many of them think their focus
should be on business and not
managing IT."
That, and Sicoob's mainframes
are likely more flexible and
powerful than any machines
the branches might purchase
for themselves. For example,
there are 202 IFLs running on
Sicoob's mainframes, with those
IFLs hosting around 500 z/VM
virtualized servers running SUSE
Linux*.
This huge adoption of IFLs and
z/VM servers has made Sicoob the
largest virtualized environment
in Latin America and the second
largest in the world, according to
Luis Franca, senior analyst, Sicoob.
"We were the first in Brazil to
process core banking with z/VM,"
he notes. "This was a great option

Sicoob has
realized
substantial cost
savings when it
comes to energy
use, to the tune

Sicoob is looking
at an overall
reduction in

than
$12 million

for us, because it has allowed
us to scale to accommodate our
continuing growth."
This was in large part why Sicoob
decided to move to the mainframe
in the first place. Prior to this nearly
wholesale move to the mainframe,
it had been using entry-level
systems in a highly heterogeneous
environment. Sicoob experienced
several problems relating to
scalability and expansion,
including low availability, large
horizontal growth, poor processor
performance, limitations related
to hardware connectivity and
convoluted platform support.
"We used to run everything on
Intel* servers, and we had many
different vendors to coordinate
with. This made that environment
very difficult to manage," Nassar
recalls. "On top of that, we were
also experiencing data center
space constraints. We were simply
running out of room and having
trouble adding additional servers
to enable us to grow."

Additional Benefits

In what some might consider a
risky move, Sicoob decided in
2007 to ditch much of its former
IT infrastructure and move to the
mainframe. Its first foray into this
arena included an IBM System z9*
running z/VM. In addition to that,
the organization also decided to
improve its entire peripheral park

by introducing an IBM SAN-based
storage model that allowed for a
high-end storage solution with
redundant SAN channels.
A year later, the organization
upgraded to an IBM System z10
with additional IFLs with the
goal of improving processing
power. In 2009, it then began
the construction of an additional
data center to meet the disasterrecovery requirements of Brazil's
central bank. When that was
completed in 2010, Sicoob then
invested in its first z196, which
included 16 IFLs. That system
took over the primary production
role of the z10, which was then
reassigned to act as a DR box.
In 2012, the second z196, with
36 IFLs, was deployed to support
the organization's businessintelligence efforts. In addition,
20 IFLs were added to the original
z196. At the same time, Sicoob
launched a Green IT initiative that
emphasized further consolidation
to decrease power consumption.
"This was made possible by our
earlier 2007 strategic decision to
move to the mainframe," Feitosa
says. "If we hadn't done that, and
if we hadn't invested so heavily
in virtualization, we wouldn't
have been able to capture that
additional benefit."
Never a shrinking violet, Sicoob
wasn't close to being finished-
and likely never will be. In 2013,
it acquired an additional 24 IFLs
for its business-intelligence box
and another 11 for its production
system. And then came the
zEC12, which hosts 49 IFLs.
"Instead of buying a lot of small,
entry-level machines, we're buying
huge machines to consolidate as
much as we can," Franca says.
"Right now, we're on a two-year
cycle to get a new machine and,
as we progress, we're stretching
ourselves even further to offer
more services to both our branches
and associates."
