Case in Point: NT on the High Seas

Every day, the Exchange server handles between 3000 and 7000 messages. In 24 hours, the crew typically transmits about 1000 messages off ship and receives an equal number from land. To support all the messaging traffic, the Navy replaced the Vinson's existing Exchange server, a homegrown 100MHz Pentium server that had 64MB of RAM and 4GB of storage, with a new Compaq 200MHz Pentium Pro server with 396MB of RAM and an 18GB RAID array.

"We're really proud of the new Exchange server because migrating from Microsoft Mail to Microsoft Exchange during the middle of a Western Pacific/Persian Gulf deployment was quite interesting," laughs Bowley. "When we were on deployment in the Persian Gulf, we were one of the few ships in the Navy that maintained an Internet mail link with the US. To say that this benefit was an incalculable morale boost would probably be an understatement," said Bowley. The ship sent and received more than 5000 Internet messages a day while in the Persian Gulf. In all, the Vinson processed nearly 1.2 million email messages during deployment in the Gulf.

The upgrade plan called for migrating one department from MS Mail to Exchange every week. The IS team delivered a set of upgrade instructions to all users. Of course, not every user followed all the instructions as carefully as Bowley would have liked. The team was able to handle some problems over the phone and use tools such as Systems Management Server (SMS). However, many problems required visiting various sites around the ship. The ship's vast size and intense level of activity while deployed made for some long days. "If you're a network administrator, you know what I mean. I think a lot of my gray hair is the result of that migration," says Bowley.

While at sea, the Vinson's network communicates with the US via the CA 3 Challenge Athena satellite system. The ship routes communications through Hawaii to Florida, and then to the rest of the country. The system performs well, and routinely permits email to travel from the ship to its destination in two to four hours.

At times during deployment in the Persian Gulf, the ship experienced transmission rates of four minutes. "Sometimes, it was almost chat-like," said Bowley. "We had a very generous bandwidth allocation because the ship's chain of command realized the importance of giving the crew the ability to communicate with their families."

In addition to email access, Web access is important. The Navy wanted to expand the network and provide more services, such as Web access. "I'd say about 200 of our clients run Microsoft Internet Explorer or Netscape Navigator. About 50 of those clients have complete Web access; the rest are restricted through Microsoft Proxy Server," said Bowley. Users on the ship regularly access Web sites such as USA Today, CNN, Navy Online, and The Bureau of Naval Personnel. The Navy Personnel site is particularly important because it contains the latest instructions, policies, and advancement exam results. "The news sites were extremely popular while we were deployed to the Arabian Gulf as part of Operation Desert Strike," reports Bowley. "The Web access permitted the crew to keep in touch with current events as they were happening, and this capability contributed very positively to morale."

Looking Ahead to the 21st Century
What's next for the Gold Eagle LAN? The Vinson's IS team is busy preparing to migrate many clients to NT Workstation 4.0 with Office 97. They're also deploying a corporate-style intranet aboard ship. Each department will have a set of Web pages for instructions and information. The IS team will use Adobe Acrobat and other Web publishing tools to create links to other pages on and off ship. "One department has already created an Adobe-based chain of command, important instructions, and standard operating procedures, all in hyperlinked text with imbedded photographs," said Bowley.

The USS Carl Vinson is a strong case for the IT-21 concept because the ship is deploying standard technology quickly and to great effect. NT has helped in many areas. "For us, it was a quantum leap," says Bowley, "I don't know how we did our jobs before."
