Met Office makes a cost-conscious and
test-driven decision to consolidate Linux
instances on the mainframe

ou check the weather
forecast on a Monday and
see it's going to be sunny
all week. Alas, on Wednesday,
it's raining. That's the curse of
weather forecasting. Occasionally,
no matter how many models are
run and how good the science,
probability runs foul of the physics.
But that's quickly changing,
thanks to the ever-increasing
power of supercomputers and
much more sophisticated modeling
capabilities. One organization
that's taking up the challenge of
improving forecasts for both its
commercial and noncommercial
customers is the Met Office, a
provider of global weather forecasts, based in the U.K.
Not only does it have a
supercomputing environment

to power its weather modeling,
but also two IBM zEnterprise*
196s (z196s) that help propagate
that forecasting information
to end users and customers.
Much of this is done thanks to
the organization's heavy and
increasing use of Linux* running
on a series of Integrated Facilities
for Linux (IFLs).
As is often the case with this
type of consolidation, Met Office
is now in the position to better
serve its downstream customers
and contain operating costs-not
to mention more accurately tell
people whether they need their
umbrellas or not.

Based in Exeter, Devon, England,
Met Office has been operating

since 1854, first providing forecasts for oceangoing ships. When aviation became prevalent, it
expanded its portfolio to serve aircraft as well.
After World War II, Met Office began using early
computers to improve its forecasting. In the late
1960s, it introduced its first IBM mainframe to
its computing lineup.
Now it offers forecasting information and
weather-related products to a variety of
customers. "We forecast for the public and
a wide range of commercial sectors, and
have a strong history of forecasting for the
marine and aviation sectors," explains
Martyn Catlow, Met Office portfolio lead
for centralized IT infrastructure. "We also
produce weather products for defense and
a wide range of retail and infrastructure
customers, such as national road and
utility services."
Notably, global climate change
research is a large aspect of Met Office's
predictions and a huge consumer of
IT capabilities, Catlow says. "The
data produced by this activity to date
amounts to around 17 petabytes and
is archived in a specially designed,
multi-storage-tier data warehouse,"
she adds.
The heavy-duty number
crunching involved in the
creation of numerical
forecasts is conducted in a
supercomputing environment
