A storage administrator needs to configure a storage pool for an application that requires high performance but also high availability.
Which data profile would you select?
Suggested Answer:
C
Double parity RAID is RAID in which each stripe contains two parity disks. As with triple mirroring, this yields high availability, as data remains available with the failure of any two disks. Double parity RAID is a higher capacity option than the mirroring options and is intended either for high-throughput sequential-access workloads (such as backup) or for storing large amounts of data with low random-read component.
Note: RAIDZ (single parity), Z2 (double parity), Z3 (triple parity)
