"In this z Systems announcement cycle, IBM has made several bold statements, not only for the new entry system, the zBC12, but also with many across-the-board enhancements that forcefully position the z Systems portfolio to meet the emerging challenges facing modern enterprises remaking themselves to deal with new customer engagement models. Many of these enhancements are delivered via the new z/OS Version 2.1."

- Mike Kahn,
Managing Director, The Clipper Group

Director, IT Strategy and Architecture,
SC Data Center,
Colony Brands

"Using Linux and the IBM z/VM® operating system on IBM z Systems, the city created a customized cloud environment which provides a scalable and secure self-service platform on which employees can develop open source applications.

- Gordon Bruce,
CIO of Honolulu’s
Department of Information Technology

"We deployed our production business analytics environment on z Systems within 11 days, providing us with an efficient platform that ensures the flexibility, availability and reliability that our users demand. Creating a new Cognos server used to take months, and now it takes just hours."

- Cal Braunstein,
Chairman and CEO, Robert Frances Group

President, Clabby Analytics

"Our two mainframes host 100 virtual servers, replacing at least 50 under-utilised x86 machines....this ultimately means that we're making better use of taxpayer money."

- Tim Simpson,
IT Support Manager, Dundee City Council
