I/O State area fields:
Device Name—Name of the disk drivers in the AIX system.
I/O Rate—Size of the input/output data in the disk driver per second.
IOs/Sec—Number of the transfer times in the disk driver per second. A transfer is an I/O request
to the physical disk. Multiple logical requests can be integrated into a single I/O request to the disk.
The size of the transferred data in each transfer is not fixed.
