IBM Adds zIIP To Mainframe Data Handling: Page 2 of 2

In a similar manner, the operating system and DB2 database have been tightly integrated to take advantage of the zIIP processor, freeing up general purpose computing cycles as data-intensive tasks are routed to the processor, Stallings said.

Bob Hoey, VP of worldwide sales, said IBM enjoyed a surge in mainframe-related revenue in the fourth quarter of 2005 that made it the highest quarter for such sales since the fourth quarter of 1998. It shipped the most MIPS or processing cycle capabilities on its mainframes in the fourth quarter in its history, he said.

Financial servers account for 65% of mainframe sales, and the financial service industry's emphasis on security and reliability are rekindling the mainframe's lease on life, he said. About 20% of mainframe sales are based on its ability to run multiple Linux systems. In some cases customers are consolidating as many as 600 Linux/Intel servers into a single mainframe running Linux virtual machines, he said.
