The company introduces the IBM System z9 mainframe in July. Representing a three year, $1.2 

billion development effort encompassing 5,000 IBM engineers, software developers, technology 

professionals and security experts from around the world, the System z9 performs as the hub in a 

new era of collaborative computing. Available in two models (the z9 109 and z9 S54), the new 

mainframe system can process one billion transactions a day, more than double the performance 

of its predecessor (the IBM zSeries z990 [ T Rex ]), run five world class operating systems, and 

process up to 6,000 secure online handshakes per second (about three times as many as before). 

IBM begins shipping the z9 on September 16. 

IBM announces the availability of its Blue Gene (

 Science & Technology) supercomputing 

system, the most powerful supercomputer, at its newest Deep Computing Capacity on Demand 

Center in Rochester, Minn. The new Center will allow customers and partners, for the first time 

ever, to remotely access the Blue Gene system through a highly secure and dedicated Virtual 

Private Network and pay only for the amount of capacity reserved.  

In February, the company rolls out the IBM eServer p5 510, designed to bring POWER5 

performance and advanced virtualization capabilities to an entry level UNIX and Linux server. In 

June, IBM previews details of a planned high density POWER5 based system for high 

performance computing. The planned 16 way IBM eServer p5 575 cluster node is capable of 

sustaining 87.3 Gflops of performance and can achieve up to 55 percent greater speed than the 

eight way IBM eServer p5 575 cluster node that was introduced in the fall of 2004. In October, 

the company debuts four new UNIX systems    including the IBM System p5 550Q, p5 520, p5 

550 and p5 505    that are equipped with POWER5+ microprocessor technology and are 

intended for small and medium sized businesses. The following month, IBM previews a pre 

release version of the upgraded high density POWER5+ IBM p5 575 supercomputer.
