Abstract:
1. A method for an Input/Output (I/O) path selection based on workload types by a processor device in a computing environment, the method comprising: providing a port workload controller being adapted to control the workload types of a plurality of ports for accessing a storage device; receiving a storage access command by the port workload controller from an application being executed on at least one virtual server on a physical server; determining the workload types related to the storage access command; determining a plurality of storage access paths between the application and the storage device having the same workload types as the determined workload types related to the storage access command, wherein storage access paths mapping data that is controlled by the port workload controller is used; selecting a selected one of the plurality of storage access paths out of the determined one of the plurality of storage access paths having the least utilization; and accessing the storage device via the selected one of the plurality of storage access paths.
