Controlling server performance
The server performance is controlled by setting the priority of the I/O operation, the upper limit,
and a threshold (per system) for the host bus adapter.
The following table shows the procedure for controlling the server performance by setting the
priority of the I/O operation, the upper limit, and a threshold (per system) for the host bus adapter.
