Measures reported by HiVSPPortUsageTest

This test provides information on I/O rates for all the host bus adapters connected to each Storage unit Port.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
IOPS Indicates the rate at which read-write operations are performed on this port. IOPS A high value of this measure is generally indicative of high I/O activity on a port. Comparing the value of this measure across ports will enable you to isolate busy ports, and detect load imbalances.
KBPS Indicates the rate at which data is transferred over this port. KB/Sec  
Response_Time Indicates the responsiveness of this port to read-write requests. Microseconds Ideally, the value of this measure should be low. If the value of this measure is very high or is increasing steadily, then, you might want to check whether the I/O operations rate measure too reports a high value. If so, it is a clear indication that since the I/O activity is high, the hosts are taking a longer time to access the disks, thereby increasing the response time.
