Explanation

NetApp has used flash to provide Flash Pool volume-level caching inside its arrays, Flash Cache caching inside its controllers, and now Flash Accel software, the three legs of the VST stool. Applications in the servers request data services from NetApp's ONTAP arrays and the read data is cached by Flash Accel in third-party flash hardware, PCIe or SSD, providing an up to 90 per cent reduction in application and server latency. Flash Accel is free to download by NetApp customers and has some API-level integration with NetApp's array software, ONTAP. It has a 2TB capacity limit.
