“HPE Adaptive Sparing is a patented way to fully flash-optimize sparing. HPE 3PAR has always addressed the need for spare space better than other architectures through distributed sparing and Adaptive Sparing extends this leadership to solid state media.
NAND flash overprovisioning is key to managing endurance, but it’s expensive and limits the stated capacity of the SSD to less than the quantity of flash chips in the device. Overprovisioning is in many ways the opposite of thin provisioning (TPVV). Thin provisioning allows HPE 3PAR StoreServ arrays to tell a host a particular VV has more capacity available than is currently written (the host believes there is more storage than is currently
provisioned). SSD overprovisioning reports less capacity than the sum of the flash chips. A 480 GB SSD, for example, might have a total of 576 GB of flash chips where the additional 96 GB (20 percent) is used for over provisioning.
Adaptive Sparing is the result of collaboration between Hewlett Packard Enterprise and SSD suppliers to return system-level reserved spare space to the SSD’s controller, allowing it to be used as drive-level overprovisioning space for managing endurance and performance. Current NAND flash technology has a property where write operations wear the flash chips and they eventually wear out. Returning spare space back to the drive means that SSD endurance is guaranteed by HPE in HPE 3PAR StoreServ arrays for five years through an unconditional drive warrantee.”

Adaptive Sparing
The HPE 3PAR architecture further extends SSD media utilization and endurance through patented Adaptive Sparing technology. To enable this
technology, Hewlett Packard Enterprise collaborates with SSD suppliers to use release capacity typically reserved by SSD suppliers for wear
management to allow HPE 3PAR systems access to a higher amount of drive flash capacity.
