Abstract:
An endurance parameter value of a non-volatile memory included in a non-volatile dual in-line memory module (NVDIMM) can be monitored and compared against a warning threshold value. In response to the endurance parameter exceeding the warning threshold value, a system alert can be generated, within a host system of the NVDIMM, to inform a system user that the NVDIMM is approaching its end-of-life. If the endurance parameter exceeds a replacement threshold value greater than the warning threshold value, an upgrade process can be initiated. The upgrade process can include copying data from the first non-volatile memory to a volatile memory of the NVDIMM and copying, in response to the first non-volatile memory being replaced with a second non-volatile memory, the data from the volatile memory to the second non-volatile memory.
