Which NetApp Virtual Storage Tier component works at the host level?

• A. Flash Pool
• B. Flash Disk
• C. Flash Accel
• D. Flash Cache

Answer: (C)

Flash Accel operates at the host level, providing caching directly on the client side to speed IO before it even reaches the NetApp storage array. This host-based caching reduces latency and increases throughput for frequently accessed data by keeping hot data on the host’s SSDs or cache software, independent of the storage system’s controllers. The other components sit on the storage side: Flash Pool is an SSD-based tier managed by the storage controllers, and Flash Cache is a controller-level cache using flash. Flash Disk isn’t a host-level VST component. So for host-level acceleration, Flash Accel is the correct choice.
