Multiprise 3000
Encyclopedia
As of late 2006, IBM
's Multiprise 3000, having the product number 7060, is physically the smallest mainframe
, introduced in 1999 and still in common use (HxWxD are 82 x 52 x 111 cm). It uses a similar case as the S/390 Integrated Server, which was introduced about one year earlier. The Multiprise 3000 is unusual because it contains internal disk storage. There is still an active resale market for the Multiprise 3000.
The Multiprise 3000 is popular among smaller mainframe customers, particularly those running the 31-bit
z/VSE V3R1 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 and VM/CMS are also compatible.) The 3000 supports subsequent OS releases, including all z/OS releases up to and including V1R5. However, the Multiprise 3000 is rapidly losing popularity among z/OS
and Linux on zSeries users because it does not support z/Architecture
. Multiprise 3000 users are upgrading to 64-bit
models, especially the System z9
BC, to run newer software such as DB2
Version 8 for z/OS. That trend has accelerated as of late 2006 given reported U.S. prices as low as $30,000 for used 64-bit z800 models and about $100,000+ for new System z9 BCs.
IBM has announced that z/VSE V4R1, due at the end of 2006, will require a z/Architecture system. This announcement may accelerate retirements of 3000s given the system's popularity with VSE users.
The Multiprise 3000 supports ESCON
and a limited number of network adapters for external I/O. There are three models available (7060-H30, -H50, -H70), that differ in the capacity and throughput and, thus, software license costs. Both H30/H50 have one main processor with 1GB/2GB of memory while the H70 model has two main processors with 4GB of memory. All models also have one System Assistance Processor (SAP). The main processors are the same CMOS chips used in the G5 series of IBM 9672, the flagship S/390 systems.

31-bit
Perhaps the only computing architecture based on 31-bit addressing is one of computing's most famous and most profitable. In 1983, IBM introduced 31-bit addressing in the System/370-XA mainframe architecture as an upgrade to the 24-bit addressing of earlier models...

Z/Architecture
z/Architecture, initially and briefly called ESA Modal Extensions , refers to IBM's 64-bit computing architecture for IBM mainframe computers. IBM introduced its first z/Architecture-based system, the zSeries Model 900, in late 2000. Later z/Architecture systems include the IBM z800, z990, z890,...

64-bit is a word size that defines certain classes of computer architecture, buses, memory and CPUs, and by extension the software that runs on them. 64-bit CPUs have existed in supercomputers since the 1970s and in RISC-based workstations and servers since the early 1990s...

IBM System z9 is a line of IBM mainframe. It was announced on July 25, 2005 and the first models were available on September 16, 2005. The System z9 also marks the end of the previously used eServer zSeries naming convention, and it is the last z/Architecture 1 machine.- Background :System z9 is a...
