System z

IBM's family of 64-bit mainframes, introduced in 2000 as the zSeries. It includes the z9, z10 and zEnterprise z196, z114, zEC12 and zBC12 models, all of which are robust, mission critical computer systems that generally run under IBM's z/OS or z/VM operating systems.

IBM's z/Architecture was a major upgrade to the previous ESA/390 mainframes. The first z mainframe was the high-end 900 line, followed in 2002 by the zSeries 800, geared to the mid-size customer. Following is a list of "z" models over the years. The enterprise class designation refers to the high-end machines. See z/OS, zEnterprise, z/Architecture, IBM branding and System/390.

Description of the procurement: the contribution service of ard, zdf and deutschlandradio (hereinafter referred to as "beitragservice") intends to use the currently used two-processor network, consisting of 2 central server systems model z196 and zec12, by purchasing two central server systems from the manufacturer ibm (probably z13s) replace.
This was accomplished through the interoperability of the z196 server with the zEnterprise Blade center Extension (zBX).
zEC12 advances performance for analytics, increasing performance of analytic workloads by 30% compared to its IBM predecessor, the z196.
The new capability of consolidating and centralizing management of Windows applications on x86-based IBM System x servers will be available for either of the zEnterprise systems -- the z196 or z114.

Also, new IBM z196 mainframes will provide greater resilience and increased capacity to support Westpac's continued growth while virtualised midrange servers and storage solutions will reduce CPU power demands and overall data centre footprint.
A water cooling option is also available for the z196 that can reduce energy use by up to 12%.
This will include new IBM z196 mainframes for greater resilience and increased capacity, while virtualised midrange servers and storage solutions will reduce CPU power demands and the overall data centre footprint.
IBM said more than a third of the new customers for its z196 mainframe, which started shipping last year, are in growth markets, or countries outside of Japan, western Europe and North America.
Since IBM's z196 started shipping in the third quarter of 2010, IBM has added 68 new System z customers, with more than one third in growth markets.
The z196 is the fastest enterprise server in the world and represents a giant leap forward in performance.
The z196 processor is a four-core chip that contains 1.
