The Amperif Cache Disk System

A description is given of the Amperif Cache Disk System, which provides high performance, large capacity, very flexible, low cost ownership storage for users of a variety of mainframe CPUs. High-speed logic combined with full read and write, track-oriented cache, multiple-channel ports, and data paths as well as disk array design give a high-performance level. The modular architecture of the system provides flexibility for a variety of host interfaces, storage configurations, and operating modes. The system uses a fraction of the floor space, power, and air conditioning of comparable products. Due care was taken to assure data integrity throughout the system.<>
