A customer buys two PS Series arrays to store data for the database servers. One array has 15K RPM disks configured as RAID 10, and the other array has 10K RPM disks configured as RAID 6. This system was chosen to meet the need to data capacity and a very high anticipated level of IOPs.
The customer reports that database servers run business critical applications. Performance is a priority for these databases. A large data warehouse holds historical data from the business used to mine data.
Which two configurations provide the fastest performance to meet the customer requirements? (Choose two.)
A. Create one pool and assign RAID preference to RAID 10 for priority applications.
B. Create one pool and let the load balancers manage page placement.
C. Create two pools, and place all log file volumes in the 15K pool and all database volumes on the 10K disks.
D. Create one pool and set a high priority level on all business volumes.
E. Create two pools, place the priority volumes on the 15K disks, and place the data warehouse volumes on the 10K disks.
Answer: AE
