The Met Office forecasts a bright outlook for Linux on zEnterprise

Saving software licensing and hardware lifecycle costs by consolidating applications and systems

Published on 27 Nov 2013

We already had a few Oracle databases running under Linux on the mainframe, as part of a pilot program we had undertaken a couple of years ago. It proved so successful that it actually set a technical foundation for consolidating more Oracle on System z.

The Met Office is the UK’s national weather service, providing weather forecasts for the public, for government, and for businesses in a wide variety of sectors. It employs 1,800 people at 60 locations around the world, and creates more than 3,000 tailored forecasts and briefings each day, as well as conducting weather- and climate-related research.

Business need
The Met Office uses post-processing systems to tailor its weather forecasts for specific clients’ needs. Running these systems on a distributed Linux infrastructure was becoming complex and expensive.

Following a comprehensive evaluation and benchmarking process, the Met Office decided to migrate suitable candidates from its distributed Linux landscape onto a pair of IBM® zEnterprise® 196 servers.

Consolidating from 204 x86 processor cores to 17 IFLs cuts Oracle licensing costs by a factor of 12. Fewer physical servers means a more manageable Linux landscape and lower hardware lifecycle costs.
