SPRING '02 FORUM
This presentation describes a practical philosophy
for building a foundation for Service Level Management. Many
different performance, capacity, and monitoring tools will be
mentioned as they relate to building a system for tracking network,
system, and application service levels. Specific design decisions
and lessons learned will also be discussed, as well as many of
the experiences of implementing an enterprise management system
for a worldwide IT infrastructure.

Content delivery networks featuring "servers at the edge of the Internet" have achieved impressive levels of performance in a number of real world situations. Some content delivery providers have made bold claims about the complexity and value of their patented "rocket science" algorithms. This paper provides an independent look at these algorithms and examines cases where they are, and are not, likely to deliver the performance benefits they promise. The paper also discusses the pros and cons of web caching, which can be viewed as a grassroots alternative to top down content delivery services.

Architectural decisions are among the earliest made in a software development project. They are also the most costly to fix if, when the software is completed, the architecture is found to be inappropriate for meeting quality objectives. Thus, it is important to be able to assess the impact of architectural decisions on quality objectives such as performance and reliability at the time that they are made.
This presentation describes PASA, a method for performance assessment of software architectures. It was developed from our experience in conducting performance assessments of software architectures in a variety of application domains including web-based systems, financial applications, and real-time systems. PASA uses the principles and techniques of software performance engineering (SPE) to determine whether an architecture is capable of supporting its performance objectives. The method may be applied to new development to uncover potential problems when they are easier and less expensive to fix. It may also be used when upgrading legacy systems to decide whether to continue to commit resources to the current architecture or migrate to a new one.
The steps in the PASA method are described together
with an overview of the techniques used to perform an architecture
assessment. These techniques include the use of architectural
styles, performance antipatterns and performance modeling as well
as strategies for identification of alternatives for meeting performance
objectives if problems are discovered. The method is illustrated
with an example drawn from an actual assessment.

Virtual tape (VT) subsystems are an important part
of a large percentage of OS/390 and z/OS 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 StorageTek 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. Primary focus
will be on VSM; however, VTS information will be included. There
will be no attempt to compare the performance and merits of different
architectures, though the techniques presented can help installations
with comparative analysis.
Storage Networks have received a great deal of publicity and are being deployed by an increasing number of companies. Storage networking is the general term used to encompass accessing storage across a network, which includes Storage Area Networks, and Network Attached Storage. With the dramatic increases in the amount of storage being deployed, many solutions are being brought to market.
In this discussion, the market segmentation for storage networking and the requirements for storage in each market segment will be explained. Making a choice between the different types of solutions being offered for storage networking in SAN and NAS is aided with an explanation of these approaches. Part of this explanation deals looking at where the different solutions best fit into a storage networking strategy.

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 presentation is new application planning, and it defines the relationship between the development process and the capacity planning function.
"Pay as you go" pricing and "capacity on demand" packaging have emerged recently as familiar themes in the marketing literature of many hardware and software vendors. However, the implementation of these concepts raises some new technical problems whose solutions are still being refined. These solutions are creating a new set of challenges for performance analysts and capacity planners. This paper analyzes a number of these challenges, with special emphasis on those associated with the IBM License Manager (ILM) and the Variable Workload License Charge (VWLC) pricing model employed in z/OS environments.
The notion of scaling used to mean "How big do we have to make the server?" Unfortunately, the new e-business approach to applications has spread the work across many different components owned by many different organizations.
Now, when we talk about scaling, we have to address networks, storage, security, application architecture, and even other entire applications. This paper proposes an approach to modeling business transactions to determine what is impeding the business process, what to do about it, and the effect of taking that action.
