Ssd Endurance; Infiniband Host Controller Adapters - Oracle ZFS Storage Appliance Service Manual

Property

SSD Endurance

SSD endurance reports the remaining life expectancy of an SSD. Endurance properties are
reported on the BUI Maintenance > Hardware chassis details page and in the CLI maintenance
chassis disk context. You can set a threshold alert when an SSD exceeds a specified percentage.
For example, set an alert to occur when one or more SSD devices exceeds a 95% threshold.
For more information, see
Guide, Release OS8.6.0.
You can use this feature to monitor the life expectancy of an SSD. For example, if SSD
endurance reports 50% after two years, the SSD is estimated to last for another two years,
assuming the workload is consistent.
Do not use reported SSD endurance percentage as an indication to replace the SSD. SSD
Note -
warranty replacements are made only when a failure is reported.

possible to offline a disk that would prevent access to data (i.e. offlining both
halves of a mirror). If the device is an active hot spare, this will also give the
option of detaching the hot spare completely. Once a hot spare is detached, it
cannot be activated except through another fault or hotplug event.
Note - Do not perform a pool configuration operation while a disk firmware
upgrade is occurring. To check if an upgrade is in progress, navigate to
Maintenance > System in the BUI, or maintenance system updates in the
