INPUT/OUTPUT PORT ROTATION IN A STORAGE AREA NETWORK DEVICE |
摘要 |
In one aspect of the present description, in an input/output (I/O) device having multiple CPUs and multiple I/O ports, a cycle of I/O port rotations is initiated in which each port rotation of the cycle includes rotating an assignment of at least one I/O port from one CPU to a different CPU of a plurality of the CPUs. In the illustrated embodiment, an I/O port assignment for each CPU of the plurality CPUs is rotated for at least a portion of the cycle. Other features and aspects may be realized, depending upon the particular application. |

1. A method, comprising:
assigning input/output (I/O) ports to a plurality of central processing units (CPUs) of an I/O adapter; for each CPU, transferring data between the CPU and each I/O port assigned to that CPU; determining whether to initiate a cycle of I/O port rotations; and upon determining to initiate a cycle of I/O port rotations, initiating a cycle of port rotations in which each port rotation of the cycle includes rotating an assignment of at least one I/O port from one CPU to a different CPU of the plurality of CPUs and wherein an I/O port assignment for each CPU of the plurality CPUs is rotated for at least a portion of the cycle. |
