A technique is described whereby, through the use of software, requested disk data blocks are selectively designated to be entered into a cache memory so as to extend the functional capabilities of existing cache used in computer central processing units (CPUs). The concept employs a software cache management technique where multiple-use software transients can be designated for cache, while other seldom-used data/program information is in a cache bypass mode. This provides the entire cache to be designated for high usage data program transient members, which are maintained by using existing cache algorithms. Non-cache designated members are transferred directly to and from the CPU and disk storage without affecting cache.
