Implementing a Business Focused Service Level Management Framework
Project management in the Internet industry, is it really the same game?
Successful organisations in this dynamic and evolving environment are re-thinking how business can achieve increased value from Information Technology (IT) by:
This paper examines why it is essential for organisations to achieve IT service excellence, and describes the challenges faced both in the construction and delivery of IT services evolving towards a business centric IT model.
It assesses the changing role of IT service delivery management, and highlights the impact of service delivery failure upon the organisation. The paper analyses why many organisations are ill-equipped to deliver IT service excellence and proposes a pragmatic approach through which organisations may manage this process to meet/exceed user/customer expectations.
What is virtulisation and why is the term having such a high focus in the IT industry? Do all uses of the word virtualisation have the same meaning? What has virtualisation to do with RAID (if anything)? Where should virtualisation be implemented - in the SAN, the Server, or the Storage system? Why should anyone be interested in virtualisation and what can it do for people's businesses?
The first reference to virtual within IT that most people can remember was in the early 1970's when IBM described the capability to have logical access to more computer memory than physically existed as "virtual storage". Today's usage of the terms virtual and virtualisation has not fundamentally changed since the 1970's. Broadly speaking, virtualization can be defined as the creation of an image or a "reality" that doesn't physically exist.
This paper looks at virtualisation in the 2000's by introducing a methodology described as the Layers of Virtualisation. This methodology identifies where virtualisation brings value to the areas of availability, capacity, performance, and storage management. The ultimate objective of this paper is to help identify answers to the questions posed above.
This paper provides insight into the Performance aspects and the Tuning
possibilities for an OS/390, WebSphere, CICS/TS, MQSeries and DB2 Java
application. The application uses Java totally for the front and back end.
Application interaction is via a browser based Java applet to a WebSphere
WAS servlet, to CICS via the CICS Transaction Gateway and then to DB2 via
SQLJ and JDBC. Background processing uses MQSeries and triggered JCICS
transactions. The talk discusses mainly DB2 V6 and CICS/TS V1.3 but will
aim to include early experiences with DB2 V7, CICS/TS V2 and WebSphere V4.
The OS/390 environment disk IO activity tuning opportunities can produce results that seem like miracles. Productive capacity of a complex can be greatly increased because IO activity tuning will also improve processor, main storage and virtual storage utilization. This presentation will demonstrate all that is needed for an effective IO activity tuning project along with the benefits achieved by such activities.
The presentation’s five major points are:
IBM's introduction of Workload License Charge (WLC) in October 2000 ushered in a new era
for capacity planners, software capacity planning. The zSeries hardware combined with
z/OS software enables usage based pricing for IBM's and other vendors' software
products. The main topics of this presentation include (a) what are the components of
variable charging for software, (b) how to gather information needed for planning, (c)
performance implications of lower cost software alternatives, and (d) sample software
capacity planning exercises.
Business today is volatile - characterised by mergers, takeovers, structural changes, new technology and outsourcing. In particular, too many large IT projects are technical successes but business failures. Often these failures are the result of insufficient attention to the people issues related to the management of change. This paper looks at the hidden costs of change, and some of the reasons why change is resisted. And offers suggestions for more effective management of change.
BS15000:2000 is the recent standard introduced for IT Service Management by the British Standards Institute.. It is a practical, common sense, best practice specification for ITSM and supports the Information Technology Infrastructure Library (ITIL) process guidelines. However, its introduction and acceptance for an outsourced environment may be anathema to external service providers. This presentation will introduce BS15000:2000, cover both practical and hypothetical aspects of its adoption in an SLA, and address a customer perception of short-term gains and long-term aims.
BS15000:2000 includes the standard, Code of Practice, and Self-Assessment Workbook and encompasses ITIL principles and philosophy. It is a management summary of the processes and relationships between:
As computer systems become increasingly complex, the task of developing and maintaining new systems becomes more challenging.
Individuals may have extensive knowledge in any one area, such as database design, IO, capacity planning, design techniques or testing. However, it is rare to find someone who truly is an expert in all of them. As a result, one of the more valuable skills is being able to approach any aspect of a computer system from the point of view of the relevant expert.
Another challenge facing us is that a project may run for a prolonged period of time. The ability to process information and note the key facts quickly is essential. Equally important is the ability to quickly retrieve these facts at a later stage of the project.
Working on a complex system also means that we have to work at different levels of detail - constantly switching from the overall system to the minute detail of a particular component.
Mind mapping is a tool that can be used to address all of these challenges and more, and the purpose of this paper is to show how this can be done.
Complex IT management, budgets, deliverables on time, utilisation, throughput, response, and availability; all issues we as IT professionals deal with on a regular basis. We know where each of these key areas are in terms of providing efficient effective IT services but unfortunately it is often not up to us to make final decisions concerning these matters. Executive management require a regular "feed" of information that they can use to manage their resources. This paper takes a look at establishing that "feed" of information to management.
In less than 12 months, Suncorp Metway has grown from 1 TB of NT data in the
SAN to over 5 TB. Of this, half is at the main site and half is at the DR
site. The two sites are connected via dark fibre and WDM links. Remote Disk
Mirroring is easy (sic). The difficult piece of the puzzle is how to put the
DR servers back together with the copies of the production data at the DR
site. This case study will examine the complexities of NT mirroring, stripe
sets, recovering file servers, Exchange servers and SQL servers as well as
other NT exotica.
In an effort to minimise the total cost of ownership of enterprise
computer systems an industry consortium (including Intel, IBM, Sun,
Microsoft, BMC Software, and others) have sought to establish a
complete set of management infrastructure standards that facilitate
the integration of various hardware and software management systems.
This initiative is called Web-Based Enterprise Management (WBEM)
and is now coordinated by the Distributed Management Task Force (DMTF).
In this paper we cover the overall goals and framework of WBEM, as
well as critically assessing both its strengths and weaknesses. We
then provide a more concrete focus and example by examining Windows
Management Instrumentation (WMI) which is Microsoft's implementation
of the WBEM standards.

How much should you invest in assuring that your business critical and customer facing applications will meet their service level metrics? A Performance Test Centre can provide predictive application performance analysis, but can you afford the investment?
This presentation describes the need, benefits and options for utilising a Performance Test Centre to assure the performance of your critical applications. Specifics that will be covered are:
History has shown that over 35% of web applications perform poorly due to issues that reside outside of an organisation's web infrastructure. This presentation outlines the benefits that your organisation can achieve from utilising hosted web load testing services to thoroughly test your web application's performance from outside your organisation's firewall.
A web-based, hosted load testing service conducts full-scale testing of your site in a matter of hours. By emulating the behavior of thousands of users against a staging server, it identifies bottlenecks and capacity constraints before your customer's site goes live.
The continuing trend of increased densities of disk drives bring with it some interesting and challenging tradeoffs, which are made extremely attractive given the lower cost points they represent. In fact, there are a lot of pressures which suggests that this increasing density, decreasing cost trend is encourageable and hence will be prolonged.
This presentation will deal with a current view of the technology itself and progress into the performance and capacity considerations which need to be addressed so that a large scale deployment of this technology and it’s named successors can be realized. Examples from commonly found workloads are used to augment the various phenomenon observed.
This presentation discusses server consolidation which is becoming an area of increasing interest to organsiation suffering from server sprawl and tightening IT budgets.
This presentation looks at:
Many organisations have recognised the need to develop e-business initiatives.
The emerging wave of e-business strategy is the transformation and integration
of all business processes to take advantage of new technology, and leverage
competitive advantage. The transformation of business processes cuts across all
IT systems, from legacy transactional systems involved in order fulfillment, to
the supply chain and customer relationship management. This is a significant
development over simple buying and selling that has characterised e-business
until recently.
The new wave of e-business initiatives has been enabled by recent developments
in middleware technology. IBM's MQSeries and MQSeries Integrator provides the
glue that makes possible such transformations in business processes. As the
essential interface between the organisation, suppliers and customers,
middleware has become the critical component for systems management.
This presentation looks at the latest enhancements in MQSeries Version 5 and
MQSeries Integrator, and discusses the requirements and importance of managing
the new components in the middleware architecture. It provides examples of the
transformation of key business processes in certain organisations, and the
systems management challenges these presented.
Workload Manager is central to two new functions in z/OS: Intelligent Resource Direction and the IBM License Manager. These new capabilities are in some ways complementary and may also be in conflict with each other.
We'll examine both IRD and ILM in detail, describe the possible areas of interaction, and suggest ways to ensure harmonious operation of z/OS in LPAR clusters with Variable Workload License Charges.
I/O performance continues to play a central role in many applications,
especially those involving very large databases, such as found in Data
Warehouses. High performance arrays, ever larger disks, and fast
interconnects enable new applications and services, but are only part
of the myriad of factors that affect performance.
The paper discusses the measurement and analysis of i/o performance,
particularly in an open-systems environment. It covers both hardware
aspects and the impact of the software layers typically encountered,
such as device drivers, logical volume managers, file systems and
application interfaces.
IT Strategic planning without Measurement might also be called daydreaming. There are always cases where reality has been bypassed in the effort to come up with a suitably inspiring strategic plan, typically ending in a suitable disaster.
Even at this early planning stage, measurement is required to give credence
to any strategy being proposed. This ounce of reality is needed to get the serious buy in of business management as to what is being proposed, how long it will take to reach fruition, and approximately at what cost.
Tools for direct measurement of Quality of Service (QoS) as represented by End-To-End Response Time (ETE RT) are gaining acceptance. However, classifications of such tools were developed before the wide commercial adoption of the Web and are, thus, out of date. In this paper, author presents an update to Tsykin-Langshaw '98 classification, with the specific emphasis on the measurement of the Web-based activities. Review of the existing tools is included and specific difficulties of operation in the Web-based environment are discussed. Future trends are indicated.
Barry Merrill's MXG has been the cornerstone of capcity planning for many organisations. It collects data from many sources - not only MVS anymore.
So why run MXG on the mainframe?
With the increased costs of running SAS on the new technology what options are there?
This paper reviews the planning process behind moving and looks at issues and problems in actually making the move form ones sites experiences.
This is a joint paper to be presented by David vasey and Steve Jack of SJCC Pty.
MVS - From 9672 to zSeries
- One sites experiences of moving from the CMOS 9672 hardware to the new zSeries that was released August 2000.
As sites around the world awaken to the dawning of IBM's zSeries, and given the decrease in hardware costs and increase in software costs, capacity analysts will require a better understanding of their mainframe environments prior to determining provisioning requirements.
This presentation will review the potential costs and challenges associated with the move to zSeries. It will present what options IBM and their partners have created to charge sites for their new hardware and software in the future and pays particular attention to the areas of:
The presentation will also look at the challenges presented to the capacity planning/management teams within a site after the migration, in particular the additional costs when workload requirements are not determined correctly.
With the advent of corporate globalisation and 'e'-business, increasingly IT organisations are called on to demonstrate the value they deliver to the business. This invariably has a major impact in the way in which they operate as both a supplier and customer. In the past data centers were run as huge cost centers that at best, broke even or at worst, run at a loss. There were huge operational inefficiencies and inevitably bad customer experiences. This ultimately resulted in a large number of corporations outsourcing their IT organisations to specific companies specializing in IT delivery (facilities management). This is not so different in today's market place, especially in the area of e-business with Internet Service providers (ISP's), Application Service Providers (ASP's) or Management Service Providers (MSP's).
Many of today's IT organisations outsource certain activities such as Storage Management, desktop environments or networks. But not all corporations want to outsource, in fact many are spinning off their IT organisations as a separate (but still wholly owned) business with their own strategies, goals, objectives, budgets, targets and management teams.
In these modern IT organisations, their customers and customer services are the key to success. Not surprisingly IT organisations are now concentrating more than ever on the quality of service and the cost of production.
IT customers on the other hand are more concerned with the purchase costs associated with IT and also the quality of their delivered service.
The IT framework that ensures customer satisfaction is a 'Service Level Management Framework' (SLMF). This paper highlights the major issues concerning the service level management dilemma of the modern IT organisation and how the SAS SLMF fits into the picture, based on our experiences at customer sites.
Project management in the Internet space has several unique challenges. Primary amongst them are the short time to market, critical nature of user interface design and usability, and ever changing requirements. Success is determined by the project team's ability to quantify, qualify and react effectively. The presenter will examine these issues and offer insights gained first hand as a project manager in this challenging environment.
