質問 32
A very small data center is being deployed at a service provider site. New 32 GB FC switches to support Open Systems hosts have been purchased and installed in the data center. Two of the tenants for data storage are from competing small businesses. Data storage for each tenant is expected to be a maximum of 500 TB.

Which array is recommended to support these requirements, while occupying the least amount of space in the new data center?
- A. VMAX All Flash 250
- B. VMAX All Flash 950
- C. PowerMax 8000
- D. PowerMax 2000
正解: B
