Processing within a computing environment that supports pageable guests is facilitated. Processing is facilitated in many ways, including, but not limited to, associating guest and host state information with guest blocks of storage; maintaining the state information in control blocks in host memory; enabling the changing of states; and using the state information in management decisions. In one particular example, the guest state includes an indication of usefulness and importance of memory contents to the guest, and the host state reflects the ease of access to memory contents. The host and guest state information is used in managing memory of the host and/or guests.

Facilitating processing within computing environments supporting pageable guests

An integrated hybrid system is provided. The hybrid system includes compute components of different types and architectures that are integrated and managed by a single point of control to provide federation and the presentation of the compute components as a single logical computing platform.

Management of a data network of a computing environment

Integration of heterogeneous computing systems into a hybrid computing system

The present invention relates to a method, a computer program product and a system for managing virtual instances of a physical port attached to a network. The method is based on the Fiber Channel N_Port virtualization for a physical Fiber Channel N_Port. Multiple virtual Fiber Channel adapters share a single physical N_Port among multiple operating system instances. The invention discloses means for the automatic and persistent generation and administration of unique Worldwide Port Names needed for the N_Port virtualization.

A computer-implemented method, apparatus, and computer-usable program code to generate unique identifiers for a logically partitioned and/or virtualized data processing system. A number of computing entities supported by the data processing system are identified to form a number of identified entities. A set of unique identifiers is generated based upon the number of identified entities. A unique identifier from the set of unique identifiers is assigned to a logical computing entity during operation of the data processing system.
