Just in time for school: Free Adeona service tracks stolen laptops Rachel Tompa rtompa@u.washington.edu As college students head back to school with gleaming new laptops, some will, unfortunately, see the last of their machine in a library, cafeteria or dorm room. And it's not just college campuses that are hot spots for computer theft, or just students who are the targets. Newspapers recently reported that airports in the United States record hundreds of thousands of laptop thefts annually. Such thefts are not only expensive, they also often mean losing sensitive data.

In early 2006, Marshall University laid out a plan to migrate HOBBIT (Figure 1), an HP OpenVMS cluster handling university-wide e-mail services. Plagued with increasing spam attacks, this cluster experienced severe performance degradation. Although our employee e-mail store was moved to Microsoft Exchange in recent years, e-mail routing, mailing list and student e-mail store (including IMAP and POP3 services) were still served by OpenVMS with about 30,000 active users. HOBBIT's e-mail software, PMDF, provided a rather limited feature set while charging a high licensing fee. A major bottleneck was discovered on its external disk storage system: the dated storage technology resulted in a limited disk I/O throughput (40MB/second at maximal) in an e-mail system doing intensive I/O operations.
