Setting the Remaining Rated Write Endurance Threshold

About this task

The Remaining Rated Write Endurance (RRWE) threshold is supported on PCIe and SAS/SATA SSDs. The Set Remaining Rated Write Endurance Threshold option provides added feature functionality in managing the threshold level for only PCIe SSDs, or SAS/SATA SSDs, or both based on your system configuration.

To set the RRWE threshold:

Steps

  1. In the Server Administrator window, under the System tree, select the Storage tree object.
    The storage Properties window is displayed.
  2. Click the Information/Configuration subtab to display more information.
  3. Under Global Tasks, select Set Remaining Rated Write Endurance Threshold from the drop-down menu.
    NOTE:  You can also click the Set Remaining Rated Writer Endurance Threshold link available on the Storage Dashboard to access this operation.
  4. Click Execute.
    The Set Threshold for Remaining Rated Write Endurance window is displayed with the following options:
    • Set Threshold for PCIe SSD (1–100) — Displays the default threshold value for all PCIe SSDs
    • Set Threshold for SAS/SATA SSD (1–100) — Displays the default threshold value for all SAS/SATA SSDs
  5. Type the threshold values for one or both the available options and click Apply Changes.
    NOTE: If you click Apply Changes without entering a new threshold value for either of the available options an error message is displayed. Enter a new threshold value and then click Apply Changes to successfully complete the task.
  6. After you click Apply Changes, Storage Management updates the system with the new threshold values.
    After the task is completed, you will be redirected to the Information/Configuration window.
    NOTE:  The RRWE threshold can be set for both PCIe and SAS or SATA SSD from PERC 9 or later family of PERC hardware controllers, SWRAID S140 or later, and all supported BOSS controllers. On PERC 9 and PERC 10 controllers, the RRWE threshold for PCIe devices is not applicable, but the values can be altered from Storage Administrator. From PERC 11 or later family of PERC hardware controllers, the RRWE threshold for both PCIe and SAS or SATA drives is applicable. For the BOSS-N1 controller, the RRWE threshold for PCIe drives is applicable.
    NOTE:  The newly entered threshold values are retained even after you upgrade Server Administrator.
    NOTE:  When the Remaining Rated Write Endurance threshold drops below the configured threshold, an Alert is logged, and the SNMP trap is received for the same. For more information about SNMP traps, see the Dell OpenManage SNMP Reference Guide at openmanage manuals.
