Which NetApp Storage Tier component works controller-wide on a FAS controller?

A.
Flash Pool

B.
Flash Disk

C.
Flash Accel

D.
Flash Cache

E.
Flash IO

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.
