OKLAHOMA CITY, Okla. (2/5/09)--Tinker FCU announced Tuesday that it is now operating in a virtual environment--which has helped the credit union save about $225,000 a year, extend branch hours by five hours and improve energy efficiency, the credit union said. Tinker is running EPISYS, a core information processing platform used by credit unions, with a virtualized Storage Area Network (SAN) environment. The virtualization allows the credit union to run multiple operating system environments on the same computer. Using the new architecture, Tinker has reduced its number of servers to 40 from 160. “We don’t have to keep growing data centers because we now store information on disk, rather than tape,” said Steve Mooney, Tinker vice president of information system operations. “This type of system is the future in technology.” Tinker has seen a 40% to 45% increase in performance with overnight processing of transactions, and a 50% to 55% improvement in backup processing. Symitar, which owns EPISYS, assisted the credit union with the virtualization. Symitar might offer the same type of environment to smaller credit unions who could not previously afford it, Tinker said. Oklahoma City-based Tinker FCU has $1.8 billion in assets.
