The technical specifications for the servers which publish EServer content to online readers.

This server runs on Macintosh OS X-based (UNIX) workstations, with twelve CPUs? with speeds up to 3.2 GHz? apiece, several terabytes (millions of megabytes) of file storage, and additional workstations for content management, database and search services, and multimedia development. All EServer computers are connected via switched [gigabit]? [ethernet]? to Iowa State University's OC-12 fiber-optic lines. As a result, our network access is exceptionally fast and reliable.

The website actively experiments with cutting-edge server-side include technologies, and offers numerous database-driven features more sophisticated than those commonly available from commercial Internet Service Providers. Contact us if you're interested in applying these technologies to online publishing projects that might be served by the EServer.

The primary workstation is an eight-processor Macintosh OS X Mac Pro, well-connected to the Internet backbone. It uses RAID 5 hard drive storage.

We aren't as happy as we'd like with the current server arrangement. It's the fastest configuration we've ever had, but could be much better. Click here to read more about our preferred server configuration.
