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. |
