Enhanced power-loss data protection
|
For data protection, Oracle Flash Accelerator F640 PCIe Card
v2 is designed with energy storage components to complete
buffered writes to the persistent flash storage in case of a
sudden power loss. These energy storage components are designed
for the life of the drives and do not require periodic
maintenance.
