Services heuristics for computer adapter placement in logical partitioning operations

摘要

A methodology for configuring the connection of adapters to bus controllers or other possibly failing components (PFCs) in a logically partitioned environment. The present invention comprises an Adapter Placement Program (APP), two Adapter Threshold Programs (ATPs), three Sequential Ranking Programs (SRPs), and three Weighting Factor Programs (WFPs). The APP determines the criteria the administrator desires to use to place the adapters on the bus controllers or other PFCs and selects the appropriate program to execute the adapter placement. The ATPs classify the adapters as either "hot" or "not hot" based on a traffic intensity threshold and place the adapters to the bus controllers or other PFCs. The SRPs rank the adapters and place the adapters to the bus controllers or other PFCs based on their rank. The WFPs assign weighting factors to the adapters and place the adapters to bus controllers or other PFCs based on the adapters' weighting factors.
