Measures reported by VrtxPowerUnitTest
VRTX is powered by two to four Dell 1100W PSUs. VRTX uses these PSUs to support both low-line (115 VAC) and high-line (220 VAC) power sources. Dell 1100W PSUs support a maximum of four PSUs with the current sharing circuitry. Critical errors in a PSU can affect the health of the power supplies in that PSU, which in turn can adversely impact VRTX operations. This is why, it is very important for an administrator to detect the failure of a PSU before it occurs and do whatever it takes to avert the disaster. The VrtxPowerUnitTest test aids administrators in this exercise.
This test reports the current status of each PSU in VRTX, and in the process, highlights those PSUs that are error-prone. Additionally, the test also points to those PSUs that are not redundant. This way, the test brings the very vulnerabke PSUs to the attention of the administrator.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Health_status |
Indicates how healthy this PSU currently is. |

The values that this measure can report and their corresponding numeric values are discussed below:
| Measure Value |
Numeric Value |
| Other |
1 |
| Unknown |
2 |
| Normal |
3 |
| NonCritical |
4 |
| Critical |
5 |
| NonRecoverable |
6 |
Note:
By default, this measure reports one of the Measure Values listed above to indicate the current health of a PSU. In the graph of this measure however, the same is represented using the numeric equivalents only. |
| Redundancy_status |
Indicates the current redundancy status of this PSU. |
