With two recent product additions to VST, NetApp now offers end-to-end Flash options spanning
from the client application through the disk subsystem. Controller level. Storage controller-based
[email protected] Flash Cache-retains hot, random read data. (You can learn more about the
algorithms used by Flash Cache and other details in a previous Tech [email protected] article.) Disk-subsystem
level. NetApp Flash Pool technology uses a hybrid model with a combination of SSDs and HDDs in a
NetApp aggregate. Hot random read data is cached and repetitive write data is automatically stored
on SSDs. Server level. NetApp Flash Accel technology extends VST into the server. It uses any server-
side Flash device (PCI-e Flash card or SSD) as a local cache that off-loads I/O from networks and back-
end storage to deliver optimum I/O efficiency to your busiest applications while freeing up server
CPU and memory resources. All three levels continue to offer the full advantages of VST, including:
Real-time promotion of hot data with high granularity. Hot data enters VST immediately, and its 4KB
granularity means that it uses Flash-based media very efficiently. Easy to deploy and simple to
manage. VST works with your existing data volumes and LUNs. It requires no complicated or
disruptive changes to your storage environment. There is no need to set policies, thresholds, or time
windows for data movement. Fully integrated. VST is fully integrated with the NetApp Unified Storage
Architecture, which means that you can use it with any NAS or SAN storage protocol with no changes.

A Flash Pool is built from a Data ONTAP aggregate in a two-step process, described in section 3,1, "7-
Mode CLI." Essentially it is the addition of SSDs into an aggregate to provide a high-bandwidth, low-
latency location that is capable of caching random reads and random overwrites.
