MISCELLANEOUS RESOLUTION #972Z8
BY: Strategic Planning Committee, Dennis Powers, Chairperson
IN RE: DEPARTMENT OF INFORMATION TECHNOLOGY - REPLACEMENT OF TWO MAINFRAME
PROCESSORS WITH AN UPGRADED SINGLE MAINFRAME PROCESSOR
To the Oakland County Board of Commissioners
Chairperson, Ladies and Gentlemen:
WHEREAS the Department of Information Technology currently has two mainframe processors,
neither of which is manufactured anymore, IBM model 4381-92E acquired in 1987 and IBM model 9121-
260 acquired in 1990; and
WHEREAS the installed version of the operating system for both processors, VSE VI R2, is
operating at or near capacity and is not Year 2000 compliant; and
WHEREAS the most current operating system available, VSE V2R2, is Year 2000 compliant and,
by enabling the consolidation of the two processors into a single mainframe, increases operating capacity
by over 100%, from 25 million instructions per second to 51 million instructions per second; and
WHEREAS insufficient capacity of the current mainframe processors precludes installation of the
necessary upgrade of the present operating system; and
WHEREAS, due to technological advances in reliability and built-in redundancies, as well as off-
loading of several piiiduction applications to client-server platforms (e.g., HRFIS and CLEMIS), the
replacement of two mainframe processors with an upgraded single mainframe processor is now feasible;
and
WHEREAS replacing the two mainframe processors with an upgraded single mainframe
processor will enable several operating efficiencies, as indicated in the attached proposal; and
WHEREAS the Department of Information Technology has investigated the costs and benefits of
acquiring a used processor versus a new processor and recommends the acquisition of a new processor
at a savings over three years of almost $112,000; and
WHEREAS the total first-year cost of acquiring one new mainframe processor (IBM model 2003-
124). including two used 3490-820 Tape Drive Units with cabling for $90,500, is $662,758, with annual
operating costs for operating system software and power/cooling amounting to $48,972.
NOW THEREFORE BE IT RESOLVED that the Oakland County Board of Commissioners
authorizes the Department of Information Technology to replace the two present mainframe processors,
and related equipment, with one new mainframe processor and related equipment at an estimated cost of
$663,000.
Chairperson, on behalf of the Strategic Planning Committee. I move adoption of the foregoing
resolution.

Proposal for Replacement of the IBM Mainframe Processors
Background
Oakland County houses two IBM Mainframe Processors, models 9121-260 and 4381-
92E. The IBM 9121-260 is rated at 16 million instructions per second(MIPS) and the
4381-92E is rated at 9 million instructions per second. The IBM 9121-260 is the
primary production system while the IBM 4381-92E serves as the production batch
processing system and the test and development system. In addition the IBM 4381-
92E also serves as a back up system to the IBM 9121-260 in event of processor failure
and contains a small on-line production system off-loading some processing of the IBM
9121-260.
The IBM 4381 was purchased on October 19, 1987 and the IBM 9121-260 was
purchased on December 27, 1990. The current operating system software is VSE
V(ersion)1R(elease)2. Both processors have been running at full capacity.
Problem
The installed version of the operating system, VSE Vi R2 is not Year 2000 compliant.
Information Technology's recommendation is to install the current version, VSE V2R2.
This would provide being at a current version of the operating system software in
addition to being year 2000 compliant. With each new version of software comes
operating system enhancements which require additional computer processor
resources to operate.
The concurrent maintenance of the production systems and their modification and
testing to become year 2000 compliant is also requiring additional processing
resources. Duplicate test systems, test application files, program source code holding
libraries, and program source code editing files must be maintained during the year
2000 testing. The 4381-92E does not have the capacity to add the new version of the
operating system and process a year 2000 test environment while maintaining the
current application development/maintenance and production batch systems. New
products, Playback and Xpediter, brought in on a trial basis which would aid in the year
2000 testing have been unable to successfully operate due to shortage of test
resources.
Table 1 below identifies the increase of on-line transactions processed for the years
1992, 115.5 million, through 1997,180.0 million estimated. This is an increase of 64.5
million transactions over a 5 year period for an increase of 56%. The respective figures
for 1993 through 1996 are: 127.0 million, 130.1 million, 140.2 million and 169.5 million
on-line transactions processed.

Table 1.
Processor performance data was collected using a monitoring product called VSE
Explorer on the IBM 9121-260. This product collects performance statistics on
processor utilization. The statistics were collected in 15 minute intervals from 6:30 AM
to 7:00 PM over several periods. Table 2 summarizes the results of the analysis
indicating that the processor was being utilized at 100% capacity for most of the prime
shift.
9121-260 Average Processor Utilization for Prime Shift
Table 2.
Although we do not have the VSE Explorer monitoring product on the IBM 4381-92E,
through observation of the performance of the guest operating systems in relation to
October 31, 1997 2
one another is a reliable indicator that this system is fully utilized. Four operating
system guests are defined to this system: the test maintenance/development guest, on-
line Future Calc production guest, production batch guest, and a technical system test
guest for installation of operating system products and fixes. Running the batch
production system guest during the day simultaneous with the other guests systems
brings the system to a near halt. Also, we are having difficulty in utilizing additional
products to aid in the testing of year 2000 conversion programs due to lack of
processor resources.
Both processors are now out of production and have been replaced with a newer
CMOS, complementary metal oxide semiconductor, technology which has reduced the
cost of the new processors. The IBM 9121 has been discontinued from manufacturing
since 1994. The IBM 4381 has been discontinued since 1991.
Maintaining two systems has added to increased complexity of system connectivity and
maintenance costs. Upgrading both systems to the new version of the operating
system would also substantially increase the operating system software costs and
would not provide the needed increase in processor resources.
Alternative Upgrade Solutions
Two alternatives are addressed. Both alternatives are directed at replacing both
processors with a single processor. With production applications being purchased
which run on different computer platforms and an increase in processing power on a
single central processor, consolidation of the two mainframes is feasible. With a single
central processor, simplicity of the mainframe connectivity and maintenance effort is
achieved. Also, a reduction in operating and software costs result.
The new version of the operating system provides for message queuing software, MQ
Series, to be installed which allows for simplicity in platform to platform
communications. MQ Series provides the ability to pass data real time between
different computer platforms. This will provide the interface mechanism between the
legacy systems and the newly acquired and/or developed client/server applications.
This will also allow the mainframe to be positioned as a server providing data to
graphical applications running on the client personal computers. It would also allow for
the elimination of the communication equipment which provides connectivity to the
State's Law Enforcement Information Network. This communication equipment,
LEMCOMs, are in need of replacement due to their age, purchased in January of 1985,
and requirement of re-starting the computer to bring them back in service after failure.
The consolidation of the two mainframes would also provide for the elimination of two
3725 communication processors and peripheral switching equipment required in today's

Table 3.
This solution provides for replacing both the IBM 9121-260 and IBM 4381-92E with a
used market IBM 9121-480 Processor. As Table 3 indicates, the purchase price of this
used hardware is $17,700. What now becomes a significant cost is the software at
$186,792 per year.
IBM is currently offering a competitive marketing program referred to as the Enterprise
System Offering. The Enterprise Server Offering which allows for a 75% discount on
the VSE/ESA software price does not apply to used processors.
This processor is rated at 37 million instructions per second which would provide for a
48% increase over the current 25 million instructions per second provided by the
combined 4381-92E and 4381-260.

Table 4.
This processor incorporates the advanced CMOS, complementary metal oxide
semiconductor, architecture. The CMOS architecture allows for a significant parts
reduction over IBM bipolar technology. Fewer parts reduces the overall cost of
purchase and operation. It provides increased processor reliability, internal component
redundancy, and onboard diagnostics and correction. On site, easy replacement of
major components is also common in this processor. This improved reliability permits
the elimination of a costly "emergency back up" computer in the configuration,
IBM's Enterprise System Offering is a "3 year, bundled" offering which includes the
2003 CMOS Processor, the VSE/ESA V2 operating system software, IBM hardware
maintenance coverage, shipping and installation and local migration consulting
services. Within this offering, the VSE/ESA V2 operating system software is discounted
75% for the next three years. This results in $316,024 of operating system software
savings over a three year period. The total three year cost for this processor is
$670,202. This ESO program will not reduce the operating system software for used
processors.
October 31, 1997 5
This processor is rated at 51 million instructions per second which would provide for a
100% increase over the current 25 million instructions per second provided by the
combined 4381-92E and 4381-260.
Recommendation
The Department of Information Technology's recommendation is to purchase the IBM
2003-124 processor. Replacing both processors with the 2003-124 would save
$111,786 over the purchase of a used 9121-480. This provides a 14% savings. This
option provides for the least purchase and operating cost, necessary increase in
processor resources required for year 2000 compliance, latest technology and
eliminates both current processors with built in reliability.

Tape Drive Replacement
Replace six Memorex Telex round tape drive units with two used IBM 3490-B40 square
tape cartridge units. The Memorex Telex units were purchased in 1985. The estimated
cost of two used IBM 3490-B40 Tape Drive Units is $80,000 plus $10,500 for
installation, shipping and cables. Total estimated purchase cost of $90,500. The
replacement would standardize on usage of square cartridge tapes.
