Unisys Corporation has announced that a recently completed Yankee Group study has found that Unisys mainframe environments, such as the ClearPath HMP mainframe-class servers, are significantly less expensive to operate than comparable IBM mainframes running similar applications. The study found that the Unisys ClearPath environment can support a similar number of concurrent users and concurrent applications with far fewer MIPS (81% less) and staff (77% less) than the IBM OS/390 CMOS environment requires. MIPS, or millions-of-instructions-per-second, is a commonly used measurement of a computer`s "horsepower" and potential speed. The Yankee Group study shows that Unisys systems can handle comparable workloads much more efficiently than IBM systems. "Our users have always known that Unisys mainframe-class environments were more efficient and less expensive to operate than comparable IBM environments," said Brian Hadfield, vice president and general manager of the ClearPath business initiative at Unisys. "We are pleased that Yankee Group has been able to demonstrate the greater cost-effectiveness of Unisys ClearPath mainframe-class servers with good, hard numbers." The Yankee Group conducted a survey of 109 IBM and 99 Unisys user companies in the United States, Canada, Europe, South Africa, New Zealand, and Australia. "The survey was designed to compare user perceptions of the Unisys ClearPath and the IBM OS/390 CMOS operating environments in terms of their relative ease of use, user satisfaction, and reliability. The survey also compared staffing levels of various key related support functions. Other issues and factors compared included the number of concurrent users, concurrent applications, and business applications " commented Mark Paterson Business Initiative Manager, Unisys SA. "Our survey is based on the real-world experience of the users of these systems," said Perry Harris, Director, Management Strategies, at Yankee Group. "Overall satisfaction and reliability were found to be equal for both IBM and Unisys, but the survey emphatically shows that Unisys systems work more efficiently and require less staff to operate." "We always knew our Unisys system cost us less to operate, we just didn`t know how much less," commented Chris Bell, chief technology officer for Rexel, Inc., an electrical distributor with 196 branches in 22 states. "We`re an $800 million dollar business, with 10,000 terminals connecting into our Unisys ClearPath server, and we do it with 11 people."
