NetApp commissioned Demartek to evaluate the performance acceleration and storage efficiency benefits of applying its Flash Cache or Flash Accel technology in a user environment, as well as the benefits of using both technologies together.
Two different application workloads were used for these tests. Each has different operating characteristics and I/O profiles.
NetApp Flash Accel is server-side caching software that is used with either PCIe flash cards or SSD drives in a server. NetApp Flash Cache is flash PCIe based hardware and software that is used in FAS and V-Series controllers.
A summary of the Demartek results.
Using either technology yields significant improvements, but using Flash Accel in conjunction with Flash Cache maximizes overall performance and storage efficiency.
In summary, either technology used by itself shows benefits, but the combined use of both technologies maximized storage efficiency.
