The CDC/Atlanta Data Center
provides comprehensive, high-performance, cost-effective mainframe computing services to
CDC and other users of public health-related information. The data center focuses
primarily on statistical, database, administrative, and financial applications.
Additionally, the data center provides large amounts of on-line storage and central
printing for mainframe computer users. These services are provided on IBM
S/390
compatible systems (including central processors, storage, communications facilities,
printers, and software) running the OS/390 operating system. The data center, operating
in an open-shop environment where users own and control their own applications, currently
provides support and technical services to more than 10,000 users. Emphasis on high
reliability in a stable computing environment ensures that critical jobs are completed on
schedule and without error.Mainframe Hardware Configuration
