7.14 Maintaining an Energy-Efficient Storage Space

The power management options in maxView Storage Manager control the power profile of the physical drives on a controller. They offer a balance between maximum performance and minimum power usage. To ensure continued operations when temperature thresholds are exceeded, you can enable Survival mode to throttle dynamic power settings to their minimum values. Spares created to protect an array are underutilized till the array state becomes degraded owing to drive failures. To achieve power efficiency gain, the inactive spares can be spun down.

To set the power management options for a controller:

  1. In the Enterprise View, select a controller.
  2. On the ribbon, in the Controller group, click Set Properties.
    The Set Properties window opens.
  3. Click the Power Management tab.
  4. In the Power Mode drop-down list, select:
    • Balanced—Set static settings based on configuration and reduce dynamically based on workload.
    • Minimum Power—Set power settings to lowest possible values and reduce power dynamically, based on workload.
    • Maximum Performance—Set power settings to highest possible values and do not reduce power dynamically.
    Note: Some controller(s) do not support Balanced and Minimum Power mode.
  5. In the Survival Mode drop-down list, select:
    • Enabled—Allows the controller to throttle back dynamic power settings to their minimum values when temperatures exceed the warning threshold.
      Note: Enabling Survival mode allows the server to continue running in more situations, but may affect performance.
    • Disabled—Disables Survival mode.
  6. In the Spindown Spares Policy drop-down list, select:
    • Enabled—Allows the inactive spares to spin down.
    • Disabled—Disables the inactive spares from spinning down.
    Note: Spindown Spares Policy is supported only in RAID and Mixed Mode.
  7. Click OK.
