HP 3PAR StoreServ 7000 Storage Site Planning Manual

Capacity Specifications
The following table lists system capacity and configuration details.
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 an HP 3PAR StoreServ under the great majority of configurations, IO patterns, and
workloads. HP 3PAR StoreServ 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
HP support contracts.
