Question

The EteX Company, which specializes in e-textbooks, is looking to provide redundant data center capabilities from its home location of Boston to a co-location facility in San Antonio. Since all textbooks are sold and accessed through the Internet, any major disruptions lasting longer than 12 hours in computing services would have a significant impact on revenue and reputation. Therefore, the company wishes to have the capabilities of quickly responding to such disruptions in their data center via a remote facility. Should a disruption occur, the remote facility should be able to resume normal computing services within 8 hours. Each data center has a centralized storage device that can provide this level of replication via the network. The main storage device holds 10TB and the update interval to the remote data center is three times per day transferring 40GB of information. Design a basic but cost effective network solution that will provide the necessary communication channel(s) between the two data storage units for the data transfer three times a day. This should include but not be limited to the type of network media or services used; required networking equipment; topology; protocols and connection types used; and how it will be managed by a single network administrator.
