Microsoft Exchange Server costs half as much as Lotus Notes Server over three years, according to findings from US market watchers Zona Reseach. Notes was labelled expensive and resource hungry in the white paper, which compared the three year lifecycle cost of ownership of the two products. Zona claims organisations can save up to 47 per cent over a three-year period if they plump for the Microsoft messaging product. The researchers concluded that Exchange Server implementations supported 430 per cent more users per server than Notes systems. While Lotus Notes supports a variety of servers, it was taken that the overwhelming majority of servers used for both Notes and Exchange are Intel servers running either OS/2 or Windows NT. Zona found that the costs associated with the server hardware were nearly the same, on a server-by server basis, but that the hardware costs of supporting Notes installations were greater because each server supported fewer users. Zona also concluded that it takes 71 per cent longer to deploy a Notes server than an Exchange server and that it takes more than four times as long to train a Notes user. Martin Penning, Powernotes channel manager at IBM, who oversees Lotus Notes working on the RS/6000 platform, was shocked at the research results and said that they did not correlate with his experience of Notes implementations. ?The scalability of Notes knocks Exchange into the ground,? said Penning. ?In this report they are not comparing apples with apples. The Lotus Notes Server is probably doing a lot more than just email...Lotus Notes supports workflow, distributed document support and document management while Exchange is predominantly email. Notes covers many different platforms, not just the Microsoft operating systems," he added.
