Abstract: A method for detection of a sequential data stream which can be performed in a data storage subsystem without host computer (10) intervention featuring examination of the channel program processed during a read operation for signals indicative that the data is not part of a sequential data stream, for example, embedded seek instructions. If a particular channel program does not contain such indications, the successive record or records may then be stated to a faster access memory device such as a solid-state cache (22). The invention is described in a plug-compatible, software-transparent configuration.

Abstract: A method of operation of a memory array for storage of records of differing predetermined sizes (Fig. 4) which features division of the array into domains which are substantially integral multiples of the predetermined record sizes. In a preferred embodiment the domain allocation may be varied adaptively in accordance with usage so as to enable more efficient use of the array (Fig. 3).
