Information About Drive Upgrades

You can install additional drives to upgrade partially populated drive enclosures.
WARNING!
feature, only use the self-encrypting drives (SED). Using a non-self-encrypting drive might cause
errors during the upgrade process.
NOTE: SSDs have a limited number of writes that can occur before reaching the SSD's write
endurance limit. This limit is generally high enough so wear out will not occur during the expected
service life of a 3PAR StoreServ Storage under the great majority of configurations, I/O patterns,
and workloads. 3PAR StoreServ Storage tracks all writes to SSDs and can report the percent of
the total write endurance limit that has been used. This allows any SSD approaching the write
endurance limit to be proactively replaced before they are automatically spared out. An SSD has
reached the maximum usage limit once it exceeds its write endurance limit. Following the product
warranty period, SSDs that have exceeded the maximum usage limit will not be repaired or
replaced under Hewlett Packard Enterprise Support contracts.
