Upgrading Network Capacity


Note: This Business Focus is a continuation of the one in Chapter 8.

The Bradley Advertising Agency (BAA) has decided to implement a parallel 40 Gigabit Ethernet network. The existing Gigabit Ethernet network will support generalpurpose needs, and the 40 Gigabit Ethernet network will interconnect servers and video-editing workstations. BAA will purchase an additional server and storage rack dedicated to high-speed, high-capacity storage for video editing. The storage rack will have a 30 TB storage array, expandable to 200 TB. The reasons for the upgrade include the following:

  • The existing twisted-pair cable was tested and found to support 10 Gigabit but not 40 Gigabit Ethernet.
  • Gigabit Ethernet will meet the demand for general-purpose networking now and for the foreseeable future.
  • 40 Gigabit Ethernet will meet current and near-term demands for video file sharing among video-editing workstations.
  • 40 Gigabit Ethernet equipment is much cheaper than InfiniBand equipment.

BAA hasn't yet developed a detailed plan for implementing the parallel network. Your job is to help them by answering the following questions:


How will the new server, storage array, and video workstations be interconnected?
