To support this massive capacity, users will have to own an eServer z900 mainframe running Linux, but the company says that this will prove to be economical, given the scalability, reliability and manageability of IBM's high-end workhorse.
Mark Levitt, research director at analyst IDC, believes this will be a strong draw for corporations with large numbers of e-mail users. "Service providers and a growing number of enterprises see centralised e-mail hosting as the preferred way to provide the scalability and reliability needed to deal with increased e-mail usage and message complexity," he said.
Companies that already use the mainframe to host business applications will naturally see the greatest cost benefit.
