ABSTRACT OF THE DISCLOSURE The disclosure relates to promotion of data from a backing store (disk storage apparatus termed DASD) to a random access cache in a storage system such as used for swap and paging data transfers. When a sequential access bit is sent to the storage system, all data specified in a read "paging mode" command is fetched to the cache from DASD. If such prefetched data is replaced from cache and the sequential bit is on, a subsequent host access request for such data causes all related data not yet read to be promoted to cache. For a certain implementation, a maximal amount of related data is promoted; such maximal amount is determined by cache addressing characteristics and DASD access delay boundaries. Without the sequential bit on, only the addressed data block is promoted to cache. TU981014
