Which external storage can be connected to PowerMax using DX emulation?
A . Data Domain
B . Unity
C . PowerStore
D . Compellent
Answer: A
Explanation:
Data Domain is the only external storage that can be connected to PowerMax using DX emulation. DX emulation is a specialized back-end DA emulation that handles SAN attached disks. DX directors are configured on existing PowerMax front-end Fibre Channel ports and are required to be implemented in pairs for high availability. DX emulation is used to support ProtectPoint technology, which integrates primary storage with Data Domain protection storage to accelerate backup and recovery. Therefore, answer A is correct1.
B, C, and D are incorrect because they are not external storage that can be connected to PowerMax using DX emulation. Unity (B), PowerStore ©, and Compellent (D) are primary storage arrays that do not support ProtectPoint technology or DX emulation.
