Capacity Planning in the
Development Cycle
Abstract
The key success factors for the forecasting task are the established and
documented relation between business activity and data processing activity and
the ability to determine the resource consumption demands of new applications.
The focus of this session is new application planning and how it defines the
relationship between the development process and the capacity planning function.
Bio
John Pilch spent 20 years working as a Member of the Technical Staff within
the Bell System, first, with Bell Laboratories, and later, with Bell
Communications Research. His seminal work in the area of benchmarking S390
environments led to a series of evaluation reports that was distributed to every
data center in the Bell System. He was also a key member of many modeling and
application sizing efforts for new/emerging applications, both in mainframe and
UNIX environments. After retiring from the Bell System, John has been applying
his application sizing talents for companies like Merrill Lynch and Aventis in
UNIX as well as NT environments. John is a fixture at CMG conferences, and has
been the 'consultant' to the Program Committee for many years - without
John, CMG would have a very difficult time in developing the materials that
manage the conference papers and sessions.

Performance
Analysis of Virtual Tape Subsystems
Abstract
Virtual tape (VT)
subsystems are an important part of a large percentage of OS/390 installations.
While, they do a beautiful job of solving many traditional tape problems, they
are not all things for all installations. VT systems present some interesting
challenges, since while they look like real tape drives to standard OS/390
performance monitors, there are important internal activities that those
monitors do not see. The two primary implementations (IBM VTS and STK VSM) both
produce SMF records which provide metrics unique to virtual tape. Approaches to
analysis will be discussed and will include both an RMF view and virtual tape
measurements. Graphical examples will be drawn from a variety of different
types of installations. While most examples will be based on STK VSM, specific
IBM VTS metric references will also be provided. There will be no attempt to
compare the performance and merits of different architectures, though the
techniques presented can help installations with comparative analysis.
Bio:
Ned is a retired IBM Senior Systems Engineer with over 25 years working with
large accounts; for over 15 years Ned was as a Large Systems Regional Designated
Specialist focusing on performance analysis and capacity planning. Ned is
currently a Senior Consultant with ISM. Primary responsibilities include
product management for the DB2, CICS, and tape library members of the PerfMan
reporting and analysis product line. Secondary functions include PerfMan for
OS/390 design assistance and customer consulting.

My Experiences
with Wireless
Abstract
Wireless
LANs based on IEEE 802.11 are worming their way into enterprise networks. Road
warriors are taking advantage of wireless "hot spots" at airports and hotels.
Teleworkers are dropping wireless gateways behind DSL and cable modems at home.
Once employees get hooked on the convenience of high-speed wireless, they become
advocates for WLAN access back at the office. Bob set up his home-office and
found out the good, the bad, and the ugly about 802.11. He walks you through
what he found out so that you can learn from his trials and tribulations."
Bio
- Bob Johnson, currently a
Technology Strategist in the
Office of the CTO at
Computer Associates, has been one of the mainstays in the performance industry
for many years. His long time association with Landmark made him well known,
first in the mainframe community, and later for his seminal work on translating
UNIX terminology for mainframe professionals. His MVS textbook was a classic,
and his numerous articles and entertaining yet enlightening presentations have
long made Bob a top speaker in the industry.

Sizing Exchange 2000
Server Based on Exchange 5.5 Workloads
Server Consolidation in the
Microsoft Exchange world has been a topic of interest lately. Exchange 5.5
Servers supported 800-1000 email users and provided a truly distributed
messaging environment for large corporations. Exchange 2000 claims to provide a
more centralized platform with capability to support 10,000+ users and reduce
TCO. This session describes a methodology to consolidate Exchange 5.5 servers to
Exchange 2000 based on existing Exchange 5.5 measurements, the transaction
profile correction factor and the Exchange 2000 scalability factor computed from
the benchmark study.
Bio: Saqib N. Syed is a consulting engineer at the Performance Assurance
R&D center, BMC Software,
Waltham. Mr. Syed has been
working at BMC Software (previously BGS Systems) for the last 6 years and has
been responsible for research and development of collection technology on
Windows NT and modeling enterprise applications. Mr. Syed has held positions at
Digital Equipment Corporation and Computer Associates as a performance analyst
and has been working in the area of performance and capacity management for the
past 8 years. Mr. Syed has a Bachelor's degree in Computer Science and
Engineering from Bangalore University, India and a Master's degree in Computer
Science and Engineering from University of Michigan, Ann Arbor, MI.
