Summary:Various embodiments for an Input/Output (I/O) path selection based on workload types are provided. A port workload controller is adapted to control the workload types of ports for accessing a storage device. A storage access command is received by the port workload controller from an application being executed on a virtual server on a physical server. The workload types related to the storage access command are determined. 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 are determined. Storage access paths mapping data that is controlled by the port workload controller is used. A selected storage access path is selected out of the determined storage access paths having the least utilization. The storage device is accessed via the selected one of the plurality of storage access paths.
