Monitoring predictive failure analysis on drivesStorage management supports Self Monitoring Analysis and Reporting Technology (SMART) on physical disks that are SMART-enabled.SMART performs predictive failure analysis on each disk and sends alerts if a disk failure is predicted. The controllers check physicaldisks for failure predictions and, if found, pass this information to iDRAC. iDRAC immediately logs an alert.Controller operations in non-RAID (HBA) modeIf 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 all properties including the following:– 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– Patrol read unconfigured areas• View all properties that are applicable to a RAID controller expect for virtual disks.• Clear foreign configurationNOTE: 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 controllersWhile 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 onthe next controller.• Schedule multiple jobs to run at a later time using the scheduling options.Managing PCIe SSDsPeripheral Component Interconnect Express (PCIe) solid-state device (SSD) is a high-performance storage device designed forsolutions requiring low latency, high Input Output Operations per Second (IOPS), and enterprise class storage reliability andserviceability. The PCIe SSD is designed based on Single Level Cell (SLC) and Multi-Level Cell (MLC) NAND flash technology with ahigh-speed PCIe 2.0 or PCIe 3.0 compliant interface. iDRAC 2.20.20.20 and later versions support Half-Height Half-Length (HHHL)211
