It emerged from a line of S/390-compatibility/coprocessor cards for PCs, but is a true S/390 system capable of server duties, having relegated the Pentium II to the role of an I/O coprocessor. It was the first S/390 server to support PCI. It had the same performance and 256 MB maximum memory capacity as the 7 years older low-end 9221 model 170. 52: 2313:
The ES/9000 family's 18 models - successors to the proven IBM Enterprise System families ES/9370, ES/4381 , and ES/3090 - provide a solid foundation for increased computing performance and function. The family's performance range spans a 100-fold growth from the compact, rack-mounted Model 120 to the

reduction from the G3. The initial G4-based models became available in June 1997, but it wasn't until the 370 MHz model RY5 (with a "Modular Cooling Unit") became available at the end of the year that a 9672 would almost match the 141 MHz model 9X2's performance. At 370 MHz it was the

As explained by IBM, the MIPS ratings are varying estimates. Besides 468 MIPS, ratings of 465, 467, 475, 480, 484.5, and 485 MIPS exist. IBM's own publication also implies 485 MIPS, but later IBM rated it 510 MIPS. For different workloads different ratings exist, calculated from IBM's LSPR ratings,

allows different operating systems to run concurrently in separate logical partitions (LPARs), with a high degree of isolation. Initially 7 partitions per a disconnected side were supported. In December 1992 the LPAR capacity of the H2 (520-based) models was increased to 10 per a disconnected side.

There are many published sources of processor capacity data available in the industry today. Most of these sources provide data in the form of MIPS tables. MIPS tables available from consultants and industry watchers are not based on independent measurements. Rather, they typically are developed

The lower 6 of the 8 water-cooled models (codenamed H0) were immediately available, but used the same processor as the 3090-J, still at the 69 MHz (14.5 ns) maximum frequency and thus with unchanged performance. Those models' main difference from the 3090-J was the optional addition of

The IBM z13 was the last z Systems server to support running an operating system in ESA/390 architecture mode. However, all 24-bit and 31-bit problem-state application programs originally written to run on the ESA/390 architecture readily run unaffected by this change.

Launched in 1994 first as the "Parallel Transaction Server" (alongside the 9673 "Parallel Query Server"), subsumed by the "Parallel Enterprise Server" launched later in the year, the six generations of the IBM 9672 machines transitioned IBM's mainframes fully to
