NOTE: The SSDs have a limited number of writes that occurs before reaching its write-endurance limit. The manufacturer generally sets a high write-endurance limit to endure degradation caused by various input/output processes and workloads over a period of time. The HP 3PAR StoreServ Storage system tracks all writes to the SSDs and reports the total percentage of write-endurance limit used by system. The constant performance monitoring provides the ability to early detect any SSDs approaching its limit and replace them before they become fully degraded. The SSD reaches its maximum usage limit when it exceeds the write-endurance limit. Any SSDs exceeding the maximum usage limit during the product warranty period will not be repaired or replaced under HP Support contracts.
