Dell PowerFlex 4.6.x Technical Overview
SMART hardware monitoring
The PowerFlex bare-metal solution provides monitoring capabilities for RAID controllers and storage devices compatible with SMART (Self-Monitoring, Analysis and Reporting Technology) protocols.
In Linux-based environments, SMART-compatible HDDs, SSDs and RAID storage controllers can be monitored for SMART attributes such as temperature, SSD wear level, and error counters. LEDs can also be lit on these hardware devices, to simplify physical identification for maintenance purposes.
Each hardware vendor defines specific thresholds for the SMART attributes. This feature currently supports storage devices controlled by LSI, HP and Dell RAID controllers, and stand-alone devices. During system deployment, an external monitoring tool is installed as part of the LIA on each node. Additional RAID controller tools must be installed manually after system deployment: storcli for LSI RAID controllers, hpssacli for HP RAID controllers, or perccli for Dell RAID controllers. These tools are used by the system to collect the counters that are returned to the MDM.
NOTE:In some cases, LSI RAID controllers may report vendor information as "AVAGO" instead of LSI.
The MDM queries the SDSs at set intervals, and stores the returned information. This information can be viewed using CLI queries. In addition, when thresholds are crossed for SMART attributes, alerts are generated by the system.
When the CLI is used to query device information, physical device information, such as serial number, disk slot information, model name, vendor etc., temperature, and wear level information (for SSDs only) is included in the returned response.
You can use PowerFlex Manager to monitor SMART-related alerts in the Alerts view.
In addition, SNMP traps and Secure Connect Gateway alert codes can be used to monitor alerts triggered by devices compatible with SMART.
