SSD Over Provisioning Optimization
Solid state devices can be optimized by deallocating all used blocks before any data is written to the drive.
The optimization process is performed when the first logical drive in an array is created and when a physical
drive is used to replace a failed drive. Not all controllers support this option.
The SSD Over Provisioning Optimization feature allows the user to disable over provisioning optimization in
the GUI.
To disable Over Provisioning Optimization:
1.
Open HP SSA.
