Abstract

Multiple field-replaceable magnetic core storage units M1...Mn are powered by a common power source PS without individual power adjustments. Such units can have different operating characteristics. For example, cores of different units can be manufactured under different conditions. To establish optimum operating characteristics in each unit which can be satisfied by one power source, an individual adjustment parameter is required based on a plot of marginal operating characteristics of the memory. This is accomplished in this instance by individual adjustments of unit operating temperatures after a best average operating condition of PS is established.

Multiple Storage Arrays Connected to One Power Source

Multiple field-replaceable magnetic core storage units M1...Mn are powered by a common power source PS without individual power adjustments. Such units can have different operating characteristics. For example, cores of different units can be manufactured under different conditions. To establish optimum operating characteristics in each unit which can be satisfied by one power source, an individual adjustment parameter is required based on a plot of marginal operating characteristics of the memory. This is accomplished in this instance by individual adjustments of unit operating temperatures after a best average operating condition of PS is established.

The best average condition of PS is calculated as the average of the best individual settings of source PS. Such settings are determined by measurements of marginal characteristics made on individual units with source PS varied and temperature maintained constant at a normal best temperature for most units.

Treating the best average power as a coarse adjustment, finer operating adjustments are made by varying individual unit temperatures with common power held constant at the calculated best average point. With best average common power and best individual temperatures thus established, if necessary through one or more iterations of the procedure, they can be maintained constant by conventional power and temperature regulating systems. The latter systems are sh...
