.. provides the base for Information Systems (IS) growth into the 'nineties:
New Model 120E provides low-cost entry point to the Enhanced 3090 Family.
Six-way model with IBM's largest single system image; up to 60% more processing power than the previous top-of-the-line IBM 3090
Up to ten-fold growth path via seven new models offering increased granularity
Price/performance and environmental benefits with up to three central processors per side
Processor storage of up to 1.28 Gb available, with maximum central storage capacity doubled from 128 to 256 Mb and maximum expanded storage capacity doubled from 512 to 1024 Mb
Expanded storage available on all enhanced 3090 models
Maximum channels increased from 96 to 128
Up to six faster optional Vector Facilities, providing up to 27-fold performance growth within the Enhanced IBM 3090 Family for users with compute-intensive applications.
.. enhances the value of the IBM 3090 as a corporate asset:
Upgrade paths to enhanced models from all previous 3090 models as well as within the Enhanced IBM 3090 Family
From 4 to 18% performance improvement between enhanced and corresponding, previously-available models
Price/performance improvements for upgrades to enhanced models from previous models.
.. provides new opportunities for users of IBM 308X:
Up to three times growth potential of IBM 308X range for commercial users and even more for compute-intensive users, offering a long-term investment comprising IBM latest, extendable large systems technology
Processor storage up to ten times the maximum 308X capacity, giving the potential for improved response times, more users, quicker job turnaround and fewer DASD paging devices
Low-cost Model 120E provides new growth path for IBM 3083 Model CX, E, EX, B and BX users
Capacity growth with reduced environmental requirements; for instance, up to three times the performance in only one and a half times the space (for the central electronic complex) when moving from an IBM 3081-KX to the new triadic 3090 Model 300E.
.. reaffirms IBM's technology and design leadership:
Most enhanced IBM 3090 models feature the faster second generation IBM one-megabit chip in central storage - the world's densest memory chip in production use for large systems today
High memory availability even with the largest 3090 storage options, using one megabit chips and multiple-bit error detection and correction in Expanded Storage
Faster cycle times; 17.2ns on Models 180E and higher, provided with improved IBM-patented Emitter Coupled Logic chips
IBM Thermal Conduction Module (TCM) chip sites increased from 100 to 132. No TCM currently utilises more than 121 chip sites, demonstrating and maintaining the extendability of the Enhanced IBM 3090 Family
Capacity of Read Only Storage for microcode doubled, permitting implementation of functional and performance enhancements.
.. highlights the importance of XA:
New triadic and six-way 3090 model supported via extensions to IBM's advanced-function System/370 Extended Architecture (XA), System Control Program (SCPs), MVS/XA and VM/XA System Facility (SF)
Enhanced four-way 3090 model supported by MVS/XA and VM/XA SF in both single-image and partitioned mode, as well as by VM/SP High Performance Option (HPO) in partitioned mode
Expanded storage supported by MVS/XA VM/XA SF and VM/SP HPO
Vector Facility supported by MVS/XA, VM/XA SF and VM/SP HPO
Enhanced 3090 uniprocessor and dyadic models supported by MVX/XA, VM/XA SF. VM/SP HPO and MVS/370
Guest performance improvements under VM/XS SF for preferred and non-preferred VM/SP and VM/SPO guests, using Virtual Machine Assist (VMA) supported under Start Interpretive Execution (SIE), assisting users migrating to XA or running applications requiring multiple SCPs.
