Example conditions to monitor

This section provides examples of conditions you can monitor. It is intended as an introduction and not as a comprehensive reference. These conditions have slightly different names, states, and values, depending on the tool you choose. For example, an SNMP MIB might have a different name than a SMI-S object or an API function.

To properly monitor these conditions, you should become familiar with the tool you choose to implement and read the documentation for that tool.

The possible states and values of these conditions are:

GREEN: Normal

YELLOW: Caution/Alert

RED: Error/Warning

You can implement your own ranges of acceptable states/values, especially if you use a data-source tool.

Device status

All of the monitoring tools return information on the status of the IO Accelerator devices, including the following states:

GREEN: Attached

YELLOW: Detached, Busy (including: Detaching, Attaching, Scanning, Formatting, and Updating)

RED: Minimal Mode, Power loss Protect Disabled

If the device is in Minimal Mode, the monitoring tool can display the reason for the Minimal Mode status.

Required actions

If the device is in Minimal Mode, the action depends on the reason. For example, if the reason is outdated firmware, then you must update the firmware.

Temperature

IO Accelerator devices require adequate cooling. To prevent thermal damage, the IO Accelerator VSL starts throttling write performance after the on-board controller reaches a specified temperature. If the controller temperature continues to rise, the software shuts down the device after the controller temperature reaches the maximum operating temperature.

These temperatures depend on the device. Newer IO Accelerator devices have higher thermal tolerances. Consult the IO Accelerator hardware installation guide to determine the thermal tolerances of all devices you will monitor. This list uses the thermal tolerances for newer devices (93°C throttling, 100°C shutdown).

GREEN: <93°C

YELLOW: 93-99°C

RED: 100°C

You can shift the conditions by a few degrees so the YELLOW condition exists before throttling occurs. For example:

GREEN: <90°C

YELLOW: 90-96°C

RED: 97°C
