Users Guide

SMART performs predictive failure analysis on each disk and sends alerts if a disk failure is predicted. The controllers check physical disks
for failure predictions and, if found, pass this information to iDRAC. iDRAC immediately logs an alert.
Controller Operations in Non-RAID (HBA) Mode
If the controller is in non-RAID mode (HBA mode), then:
• Virtual disks or hot spares are not available.
• Security state of the controller is disabled.
• All physical disks are in non-RAID mode.
You can perform the following operations if the controller is in non-RAID mode:
• Blink/unblink the physical disk.
• Configure the following properties:
• Load balanced mode
• Check consistency mode
• Patrol read mode
• Copyback mode
• Controller boot mode
• Enhanced auto import foreign configuration
• Rebuild rate
• Check consistency rate
• Reconstruct rate
• BGI rate
• Enclosure or backplane mode
• View all properties that are applicable to a RAID controller expect for virtual disks.
• Clear foreign configuration
NOTE:
If an operation is not supported in non-RAID mode, an error message is displayed.
You cannot monitor the enclosure temperature probes, fans, and power supplies when the controller is in non-RAID mode.
Running RAID Configuration Jobs On Multiple Storage
Controllers
While performing operations on more than two storage controllers from any supported iDRAC interface, make sure to:
• Run the jobs on each controller individually. Wait for each job to complete before starting the configuration and job creation on the
next controller.
• Schedule multiple jobs to run at a later time using the scheduling options.
Managing PCIe SSDs
Peripheral Component Interconnect Express (PCIe) solid-state device (SSD) is a high-performance storage device designed for solutions
requiring low latency, high Input Output Operations per Second (IOPS), and enterprise class storage reliability and serviceability. The PCIe
SSD is designed based on Single Level Cell (SLC) and Multi-Level Cell (MLC) NAND flash technology with a high-speed PCIe 2.0 or PCIe
3.0 compliant interface.
Using iDRAC interfaces, you can view and configure NVMe PCIe SSDs.
The key features of PCIe SSD are:
• Hot plug capability
• High-performance device
The PCIe SSD subsystem consists of the Backplane, PCIe Extender card which is attached to the backplane of the system and provides
PCIe connectivity for up to four or eight PCIe SSDs at the front of the chassis and the PCIe SSDs.
You can perform the following operations for PCIe SSDs:
• Inventory and remotely monitor the health of PCIe SSDs in the server
• Prepare the PCIe SSD to be removed
