Which HPE 3PAR StoreServ virtualization technology provides DRAM cache extension to reduce application response time for read-intensive I/O workloads?
A. Priority Optimization
B. Adaptive Flash Cache
C. Persistent Cache
D. Rapid Provisioning
Correct Answer: B
Explanation/Reference:
With HPE 3PAR Adaptive Cache enabled, the system satisfies read requests by using DRAM cache up to a threshold of 90 percent utilization, at which point small blocks of random read data are automatically destaged to the virtualized cache extension created from SSD capacity. Similarly depending on the I/O request small block random write requests will be de-staged from DRAM to Adaptive Flash Cache.
