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. Because tenants are from competing companies, the service provider wants to be able to provide data storage from different arrays to each tenant to guarantee separation of data and information.
Which array is recommended to support these requirements, while occupying the least amount of space in the new data center?
