**IBM S/390 Multiprise** was a short-lived series of small, compact, entry-level [mainframes](/source/IBM_mainframe).

## Multiprise 2000

The first model of the Multiprise series, the **Multiprise 2000**, was released in 1996[1] as a compact and affordable version of [S/390 G3](/source/IBM_System/390#9672) mainframe.[2][3]It used the same technology as the 9672 G3, but it fit half as many processors (up to five) and its off-chip caches were smaller. The 9672 G3 and the Multiprise 2000 were the last versions to support pre-XA [System/370](/source/System/370) mode. In October 1997 models of Multiprise 2000 with an 11% higher performance were launched.[4]

## Multiprise 3000

The **Multiprise 3000** (product number **7060**) was a compact [mainframe](/source/IBM_mainframe) measuring just 82 x 52 x 111 cm introduced in 1999.[5] There were three models available (7060-H30, -H50, -H70), that differed in the capacity and throughput and, thus, in software license costs. Both H30/H50 had one main processor with 1GB/2GB of memory while the H70 model had two main processors with 4GB of memory. All models also had one [System Assistance Processor](/source/System_Assistance_Processor) (SAP). The main processors were the same CMOS chips used in the G5 series of [IBM 9672](/source/IBM_9672), the flagship S/390 systems.

The Multiprise 3000 had [ESCON](/source/ESCON) channels and a limited number of network adapters for external I/O. It had a similar use case to that of the [S/390 Integrated Server](/source/PC-based_IBM-compatible_Mainframes#S.2F390_Integrated_Server), which was introduced about one year earlier. The Multiprise 3000 was unusual in that it contained internal disk storage.

IBM also produced a 7060-H55 which was built on the 9672-R16 platform and a 7060-H75 which was built on the 9672-R26 platform. These machines are sometimes referred to as "the secret 7060". The 7060-H55 and 7060-H75 had OSA network adapter capabilities which allowed the network to talk across multiple LPARs. The 7060-H30, H50 and H70 were not OSA capable and would require one network adapter per LPAR with a limit of four.

Models H50 and H70 were withdrawn from marketing in 2002.[6] Withdrawal of service for all models occurred at the end of 2012.[7]

The Multiprise 3000 was popular among smaller mainframe customers, particularly those running the [31-bit](/source/31-bit_computing) [z/VSE](/source/Z/VSE) V3R1 [operating system](/source/Operating_system). Initially supported OSes were OS/390 V2R4 through R8, VM/ESA V2R2 through R4, and VSE/ESA V2R2 through R4. (The 31-bit versions of [TPF/ESA](/source/TPF/ESA) and [VM/CMS](/source/VM/CMS) are also compatible.) The 3000 could run subsequent OS releases, including all z/OS releases up to and including V1R5. However, the Multiprise 3000 rapidly lost popularity in the 21st century among [z/OS](/source/Z/OS) and [Linux/390](/source/Linux_on_IBM_Z) users because it did not implement the full [z/Architecture](/source/Z/Architecture) architecture.

IBM's announcement that z/VSE V4R1, released in 2006, would require a z/Architecture system accelerated retirements of MP3000s given the system's popularity with VSE users. Multiprise 3000 users mostly upgraded to [64-bit](/source/64-bit_computing) models, starting with the [System z9](/source/System_z9) BC, to run newer software such as [DB2](/source/IBM_Db2) Version 8 for z/OS. That migration has largely completed as of 2022, though anecdotally via mailing lists it appears that some shops still are running on what is now a completely unsupported system.

As of late 2006, the Multiprise 3000 was physically the smallest [mainframe](/source/IBM_mainframe) in common use, but modern [IBM zSeries](/source/IBM_Z) mainframes are more productive and energy efficient.[8]
