A customer with multiple Oracle databases reports that user are experiencing slow application
response time. You need to create an optimized solution for this customer. You have already done
database performance motoring using Oracle AWR, server and storage performance monitoring.
You discover that there is a high I/O Walt and the average I/O latency is -30 ms. which is causing slow
response times.
Which solution should you propose to address the performance problems?
A.
HPE 3PAR storage array with high performance spinning disks with HPE 16 Gb/s StoreFebric
B.
HPE 3PAR hybrid storage Array with spinning disks. Adaptive Flash Cache and AO with HPE 16 Gb/s
StoreFabric
C.
HPE 3PAR all=flash storage array with HPE 16 Gb/s StoreFabric
D.
HPE 3PAR Storage Array with a sufficient number of spinning disks with HPE 16 Gb/s StoreFabric
C. HPE 3PAR all=flash storage array with HPE 16 Gb/s StoreFabric

B. – Adaptive flash cache reduces application response time for read intensive I/O workloads and can improve write throughput in mixed-workload environment. Adaptive Flash Cache effectively increases the amount of random read data cached on high-speed media on a node. By doing this, Adaptive Flash Cache can increase the overall random read IOPS an array can deliver by “unloading” the back end of the array potentially resulting in increased write throughput on the array. Using SSDs as Level-2 read cache to hold random read data that has aged out of DRAM cache is a cost-effective way of keeping more random read data on very fast media to improve overall system performance.
