The Qumulo software uses erasure coding to ensure data redundancy. By design, the drives are unconfigured or are configured as single physical drive RAID 0 logical drives in the Smart Array controller configuration so that they are presented individually to the Qumulo software.When redundant hardware RAID is not used to manage drives, processes such as background surface scans, disk error handling, and latency management should be handled by the operating system, filesystem, or software stack.The Qumulo software monitors drives for errors and latency that may not yet have resulted in a drive failure. The software marks the drives as offline when pre-determined thresholds are reached. When a drive is marked offline, Qumulo may send a case to HPE or may encourage the customer to work with HPE to replace the drive.
