IBM 2094 System z9, open front with one Support Element IBM 2094 System z9, rear IBM 2094 System z9, open rear. IBM System z9 is a line of IBM mainframe computers. The first models were available on September 16, 2005. The System z9 also marks the end of the previously used eServer zSeries naming convention. It was also the last mainframe ...
In July 2005, IBM announced a new family of servers – the System z9 family – with the IBM System z9 Enterprise Class (z9 EC) and the IBM System z9 Business Class (z9 BC) servers. The System z9 servers offered:
IBM introduced its first z/Architecture-based system, the z900, in late 2000. [1] Later z/Architecture systems include the IBM z800, z990, z890, System z9, System z10, zEnterprise 196, zEnterprise 114, zEC12, zBC12, z13, z14, z15 and z16.
An IBM System z9 mainframe A mainframe computer , informally called a mainframe or big iron , [ 1 ] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses , industry and consumer statistics , enterprise resource planning , and large-scale transaction processing .
In IBM System z9 and successor mainframes, the System z Integrated Information Processor (zIIP) is a special purpose processor.It was initially introduced to relieve the general mainframe central processors (CPs) of specific Db2 processing loads, but currently is used to offload other z/OS workloads as described below.
The IBM System z Application Assist Processor (zAAP), previously known as the zSeries Application Assist Processor, is a mainframe processor introduced by IBM in 2004. zAAP engines [1] are dedicated to running specific Java and XML workloads under z/OS, accelerating performance. zAAPs are available for zSeries 990 and 890 servers and later zSeries and zEnterprise models.
Starting with System z9 running z/OS 1.7, IBM offered the multiple-subchannel set facility, which allowed up to four independent sets of 64 Ki subchannels. [3] The installation was responsible for defining the Input/Output Configuration Data Sets (IOCDS's), and the operator could select a specific IOCDS as part of a power on reset (POR).
Transaction Processing Facility (TPF) [2] is an IBM real-time operating system for mainframe computers descended from the IBM System/360 family, including zSeries and System z9. TPF delivers fast, high-volume, high-throughput transaction processing, handling large, continuous loads of essentially simple transactions across large, geographically ...
