Architecting and utilzing this new computing model has unique challenges and is only suitable for a specific set of usage scenarios.This session will begin with an introduction to Cloud Computing, describing the service model and architecture of some of the most popular Clouds including Amazon's EC2 and Google's App Engine. The discussion will focus on the similarities and differences between each service and the pricing model that each provider offers. We will then dig deeper and explore the following topics in more detail:• Storage as a Service - we will discuss storage infrastructure of virtually unlimited capacity that is made available in the cloud in different forms and through various access models.• Database resources - in addition to computational and storage resources, providers are now offering database resources as a service• Architectural Concerns - we will close by discussing the unique challenges that you need to be aware of before deploying an application in the Cloud including reliability, load balancing, and SLAs.

A significant limitation, however, is monitoring modern applications, which are usually tiered across multiple hosts. How do you combine a variety of monitored data from multiple hosts so as to correctly assess distributed capacity and meet service level objectives? Pretty Damn Quick (PDQ) is a FOSS capacity modeling tool, now in release 5 from SourceForge.org. It has been used over the past 15 years by several corporations as part of their routine capacity planning, and it was written up in Linux Technical Review issue 02, 2008. Rather than requiring you to learn a separate modeling language, PDQ makes use of standard programming languages like: C, Perl, Python, Java and R, and it can be installed on most platforms: AIX, Linux, Mac OS X, Solaris, Windows, z/OS. Participants in this workshop will learn how to apply PDQ to solve multi-tier capacity planning problems associated with multicore servers, an anti-spam farm, a tiered e-business application, a client-server insurance application and more.

So why do we spend so much time trying to squeeze even more out of the processor side of the equation when I/O improvements offer substantially more benefits in overall application performance?Improvements in zSeries architecture has removed many of the historical bottlenecks from the I/O subsystem. As most of us in the real world know however, removing one bottleneck usually just creates another. This is certainly the case today as an ever increasing burden is being place on Disk Subsystems. This means we need to adapt our perspective from the standard RMF/LPAR view to that of the Disk Subsystem. The workshop will walk you through the necessary steps to achieve this level of visibility and spot the new bottlenecks using nothing more than readily available RMF data.Looking inside the box, we will explain the differences between the various disk drive options available today. High performance options such as solid state vs cost effective SATA technology, provide dramatic opportunities for both performance improvements and cost savings. The workshop will provide a scientific, unbiased comparison of these options so that you can make effective decisions for your data center.Finally, the Pros and Cons of the various Data Replication solutions will be discussed.This workshop is designed to provide attendees with the knowledge to better understand the performance and utilization of their storage environment, regardless of their size or choice of storage vendor. All of the samples are from real world data; nothing has been artifically created.As a bonus, John will provide a free I/O performance analysis of your environment including Excel charts and graphs to take home.

In enlightened times of sustainability, it is an advantage to satisfy 'green' criteria. In tough times of need for competitive advantage, it is wise to adopt a mean and minimalist approach to all practices. Thus, the pragmatic 'lean, mean, green capman solution' is to promote the same core practices that have been used for years. The 'more' to be done usually means more applications in more services on more servers for more users of more critical business requirements. The 'less' available usually means less available resources on all fronts. The 'more' has to relate to what is actually achieved (in a business sense) and the 'less' has typically to be financially assessed. Thus the traditional needs for baseline definition, workload characterisation, business drivers, monitoring, analysis and forecasting are all involved. Based on previous master-classes and a book published this summer, Capacity Management: a Practitioner Guide, this workshop also describes experiences in capman consultancy and gap analyses at a number of sites. It pays due respect to the concepts described within ITIL® but it tries to provide practical ideas for cost-effective implementation.Objectives:To familiarise participants with tried and tested practices for managing the performance and capacity of existing IT infrastructures, predicting future demand and assessing its impact on the ability of that infrastructure to continue to meet required service levels.The workshop will describe a coherent set of processes and techniques for an organisation to:• Optimise their IT investment and be able to respond to business needs• Achieve the optimum balance between service quality and cost• Provide IT services required to support the business reliably, consistently and at justifiable cost.

Originally used in Mechanical Engineering, it has become one of the main Six Sigma tools to optimize business processes, and after some adjustments it is used in IT Capacity Management area especially in “behavior learning” products.During the workshop the following topics will be discussed: What is the Control Chart? Where the Control Chart is used: review of some systems performance tools that use it. Control chart types: MASF charts vs. SPC. Gallery of published charts in CMG papers plus some new ones with explanations on how to read them. How to build a Control Chart: using Excel for interactive analysis and R to do it automatically. This session includes a live demonstration of Excel to build different types of control charts against real performance data. Attendees will be provided CDs with the data in spreadsheets and will build Control Charts themselves with their own data. Finally, they will be able to run an R-script to build a Control Chart based on input CSV data. This workshop is based on series of CMG papers about Exception Detection System (SEDS) published by the author. The prototype of the workshop was presented twice this year in Southern CMG meetings in VA and NC.

Green Capacity Planning extends the scope of traditional capacity planning to include power/energy as a new resource.We will review the basic steps for applying Green Capacity Planning including the methodology, terminology, key metrics and practical application of the approach. Three case studies will be used to demonstrate the process.The intent of the cases studies is to:• Apply Green Capacity Planning using a typical system sizing exercise (that includes virtualization)• Interpret “green” data and analysis results• Guide solutions based on energy, space, cost and capacityAfter attending this workshop you should have a much better understanding of how to interpret and apply “green” factors in your capacity planning studies. In addition, you should be able to cut through the hype and quantify the value of “green” industry practices.Green Capacity Planning is a new methodology that will increase your value as capacity planners and reduce the drain on constrained, aging data centers (and the energy grid).

Since its debut in Solaris 10, it has been attracted a wealth of development, including libraries of canned scripts, numerous enabling GUIs, and incorporation into Apple's OS X operating system. The possibilities for using DTrace for performance analysis are endless, and the opportunity for leveraging it for capacity planning remains largely unexplored. In this workshop, we'll give an intensive introduction to DTrace for users of all sorts, show how to incorporate DTrace probes into an application (including a case study), and scratch at the surface of possibilities for applying DTrace to capacity planning. We will illustrate some possibilities for transaction-level resource accounting using DTrace, with the intention of fueling development of continued innovation in performance and capacity management.

This requires that we read in the data, convert it to a representation that is easy to process (e.g., spreadsheets, matrices, vectors, etc.), perform various calculations (e.g., average throughput, regression analysis, response time by transaction, etc.), and present the data in various formats (reports, graphs, web pages, etc.) so that others can understand what it means.Many of our vendors may provide tools that work with the specific data that their products collect, but if we have to merge data from different sources (e.g., the application log files), we have been faced with having to write our own scripts to analyze the data. This would include using Excel, SAS/SPSS, and specialized Java/C programs. And all these operations may have to be carried out each day for hundreds of systems that we might be responsible for.This workshop will introduce the student to the Open Source software called R. This is a statistical programming environment that has been around for over 20 years in the form of S/SPLUS which was developed at Bell Labs. This is an interactive environment that allows the quick development of a script and then the script can be run in a batch environment for repeated executions. This is very similar to the way that the UNIX "shell" is used; you can interactively try out commands and then store them in a script. This workshop will provide the basics of the language and will use some performance data ('vmstat' and 'ps' from UNIX/Windows) to illustrate the commands. Scripts will be provided so that the student can implement these operations on their systems.R can easily handle datasets of several million entries. Even though it is an interactive environment, the core routines are written in C/FORTRAN. On my laptop I can take a data file of 2 million transactions, and their response times, and compute the average response time for each transaction in less than 1 second. Histograms of the response times for each transaction can also be generated in under 1 second. Just try that with Excel.The power of R is that it is a programming environment that has all the statistical functions you could ever want built-in. It other major feature is the ability of producing production quality graphical output in various formats (JPEG, PS, PDF, PNG, BMP, etc.). R runs on most commonly available platforms: Linux, UNIX, Windows, and Macs. The language and data are portable across these platforms. R can also interface to any relational data (via RDBC/JDBC) to manage the storage of data. So R is another tool that you can add to your analysis toolbox to augment the ones that you are already using.

Too, computing in the cloud has its own issues: Where is my data? Who is responsible for back-up? How do I protect against a small company with clever software disappearing? And how do I apply the same principles of governance to SaaS applications and users that I apply to internal ones?Amy Wohl has been covering the SaaS market since its beginnings in the late 90’s. She is the author of the book Succeeding at SaaS: Computing in the Cloud. She speaks to dozens of SaaS ISVs and platform providers every month. This session will look at how the economy is impacting IT and how SaaS will be implemented as a solution. It will emphasize the role of IT staff in managing SaaS applications to insure that they meet the standards of an enterprise data center.

The goal of this paper is threefold. First, to introduce the design, architecture, and features of Btrfs and ZFS. Second, to compare the 2 filesystem architectures and to elaborate on some of the key ''performance by design'' concepts that are embedded into the frameworks. Third, to conduct an actual empirical analysis, comparing the performance behavior of Btrfs and ZFS under varying workload conditions, utilizing an identical HW/SAN setup for all the benchmarks.

Typical areas of application are datacenter consolidation and what-if analysis. Unfortunately, each server comes with different configurations (e.g., number of processors, memory size) while the published SPEC results are available only for a small subset of the configurations; typically the most powerful. The problem we are trying to solve in this work is how to scale down or up a SPEC result in order to account for different numbers of processors with respect to the benchmarked configuration.

In this session a strategy will be outlined for avoiding this dilemma. In particular, a description of how to architect cloud computing not simply as a replacement for the data center, but as its reinforcement will be provided – a way to deliver a rich set of information services with unbounded processing power into the very fabric of the data center. Following the same reasoning, the data center should be considered not just as old infrastructure that the cloud supersedes – but as a new unit of management that the cloud sustains and supports. The next revolution in computing is a "both-and": cloud computing meets the virtual data center.

In a complicated batch schedule, determining which jobs are on the critical path can be a seemingly daunting task. Various commercial products can be used for this task, but they may not be necessary. The code needed to determine which predecessor jobs constitute a particular job's critical path is relatively, perhaps surprisingly, simple.

Indeed, load testing by definition is performed in a dedicated and isolated environment, without any performance interactions with other services. On the other hand, production environments have different hardware configurations and can leverage virtualization technologies to consolidate different services, therefore creating performance interactions between different services.

We know an an update to a row or delete of a row can never be index-only. So, how can the INDEX_ONLY column on the PLAN_TABLE be "Y" for maintenance SQL? A third mystery is the fact that adding an ORDER BY clause to an SQL statement might actually ELIMINATE a SORT! And the fourth and final mystery (and perverse fact) is that removing an ORDER BY clause can actually introduce a SORT into your access path.

This study came about as a result of multiple IT management vendors providing metric base-lining (or dynamic thresholding) capability based on the assumption of normally distributed data. This study will show that IT data does not behave normally and in fact takes on an infinite number of distributions. Thus any base-lining techniques using normal distribution assumption as the basis of their analysis will be significantly inaccurate.

But many businesses have critical work which runs periodically (daily, monthly), non-interactively, and with an elapsed time requirement (“batch window”). Elapsed time prediction utilizes different modeling and analysis techniques when compared with interactive workload analysis. These techniques are outlined and applied in three case studies (UNIX/Windows systems): (1) one very resource-intensive job (2) multiple simultaneous jobs and (3) hundreds of smaller jobs.

This has for example, caused the typical performance bottlenecks to shift from the host to the components inside the disk subsystem. But I/O performance reporting has not kept up with the latest architectures and it is very difficult to see what is going on inside the disk subsystem. This results in bad surprises from time to time, but also in overspending on hardware.

Most user workloads fluctuate unpredictably. These fluctuations are traditionally characterized by random variables, leading to stochastic models of system performance. This session presents an alternative characterization of uncertainty that does not employ random variables or other standard probabilistic concepts. The approach provides a new way to separate risky predictions from safer predictions derived from the same model.

As a result, server troubleshooting and performance management has changed since its emergence. In this presentation we will review the various changes and focus on the specifics and similarities of the three major players in the market today : IBM AIX, SUN Solaris and VMware ESX.

This paper provides an overview of cloud computing, a discussion of the different types of cloud computing models, and the impact of these models on capacity managers. Specifically, the paper will discuss how the three major sub-processes of the ITIL model for IT computing are impacted by the three emerging cloud computing models.

There were a couple of papers at CMG'08 that got me thinking about how the functionality could be done with ''R''. Specifically these were papers on the use of pivot tables in Excel and on using ''sparklines'' to present information in a concise format. Through the use of examples, I hope to whet the reader's appetite in considering adding ''R'' to their toolbox.

Wouldn't it be nice to break it out into application vs. network time? In the first part of this session, we will show how you can get response time for various TCP applications such as Telnet, CICS, FTP, and web server. Then, we will discuss how to think about response time monitoring for Enterprise Extender.How do we define, match and break out a transaction into its components when so many headers are involved? We will again see if we can break out the time into application and network time, this time for packets flowing over HPR over UDP.

However, there are easy ways to figure out what causes the system to slow. TCP/IP flow patterns and Java application’s response time patterns are very useful to come up with solutions.This research will trace patterns that initiate the response time slowness of the online web based system by the pattern, and guide the solutions for systems to respond quickly.

Topics such as data growth, access patterns, traffic characterization, and the working set are used to introduce the need for technologies such as larger drives, flash disks, multi-tiering, dynamic cache partitioning, virtual provisioning and the like. Further, it examines the technologies, their lifetime expectancies, and their suitability to various workloads and applications.

To truly understand how an application performs, the impact of poor performance and to quickly identify the fault domain, one must correlate Synthetic and Real End User Monitoring. Learn how a holistic approach to APM brings visibility through the Front-End, Middleware and Back-End database calls. The result is good Service Quality- the representation of a business service to meet its goals and deliver value.

An effective analytical engine can also help correlate between business, application & infrastructure views and thus help justify value to respective stakeholders. It can also be a means to plan capacity for future growth, expansion & mergers.

This is a critical task and can save hard dollars in both CPU time taken by the stack and in the bytes transferred over the network. In our work, we have seen from 20% - 80% overhead at many companies, which can be eliminated fairly easily.In this session, we will discuss:• Unneeded traffic - where is it generated?• Unnecessary TCP sessions - why?• TCP errors which can be eliminated.We will conclude by looking at productivity on Enterprise Extender networks.

While for a single exposure I/O device service time characterization limited to the mean and the standard deviation is sufficient to predict the average I/O time in a realistic model, it is inadequate with PAVs. We also consider methods for matching real-life workload distributions to phase-type distributions, used to enable numerical solutions of queues with multiple servers, and we point out potential pitfalls related to their use in modeling the performance of PAVs.

Is that really the case? This paper discusses how High Availability, Load Balancing, Multiple Standards (platforms, operating systems, middleware services, etc.), and Application Incompatibility affect the amount of computing capability which is actually usable. Can you explain to executive management why 25-30% peak CPU utilization is reasonable if you engage in a lot of HA, load balanced, and multi-platform solutions? Would you like to be able to?

Multi-address space application scenarios use a combination of velocity and response time goals across multiple WLM service classes to manage performance. In addition, some of these workloads are also eligible to be redirected to zIIP and zAAP specialty engines on your System z processor. Let's connect all these pieces together to understand WLM management of enclaves and what makes work eligible for zIIPs and zAAPs.

It uses a nonparametric approach that handles continuously distributed and discrete data, detects significance, enables predictions, evaluates time to events (response time) and allows event censoring (equipment swaps). This session will provide insight into how Cox Regression Analysis works and how it was used with SAS to identify critical components of computer performance and capacity problems. This methodology worked and helped improve performance in previously intractable areas.

This session analyzes a multi-class queuing model, which evaluates if job's response time goals are reachable, and if not, what would be, in some sense, optimal alternatives. This model may be useful to estimate the limits of tuning, or to compare alternatives between hardware upgrade and tuning, or estimate a minimal necessary level of the hardware upgrade to reach a given set of response time goals.

The performance metrics to monitor are the following: • Congestion window• Round trip time• Round trip variance• Retransmissions• Duplicate acknowledgments• Bad status• Hung connectionsIn this session, we will discuss baselining for TCP/IP. Setting appropriate thresholds may be the most critical portion of this whole task. You may have 'Red letter days' in your industry. These are very high volume days. On such days, the thresholds should be different. In this session, we will discuss all the complexities of baselining and how to do this automatically.We will end by discussing an interesting security requirement from the U.S. Federal Government's Office of Management and Budget. The memo OMB 06-16 states that mobile and remote access devices should be reauthenticated after 30 minutes of inactivity. We will discuss how this may be accomplished and some of the pitfalls.

Software testing requires dedicated test labs with a need for constant scale-up of resources. This paper discusses the approach to combine Grid Computing with Virtualization technologies for creating Virtual Test Labs that use the spare CPU cycles of underutilized systems. Virtual Test Labs powered by idle desktops, results in reduction of operating cost and energy expenses with an offshoot of having a positive impact on the environment.

Measuring the host resource usage is straightforward and the necessary tools are included with most virtualization environments. However, complexities introduced by the different virtualization techniques create problems with measurements within the guests, resulting in missing model parameters. This session shows how to use the Menascé technique that computes missing parameters with the Simalytic Modeling technique to predict application performance more effectively in virtualization environments.

We show how the understanding of these distributions contributes to developing accurate models that predict IT service end-to-end times. During this session, another approach to computer performance modeling, simulation modeling, is introduced. The basics of simulation modeling to predict computer performance are presented.

It builds supervised learning models for single or multiple workloads. STA identifies and ranks performance events (e.g., branch mispredicts, cache misses) in terms of their contribution to execution cycles and optionally locates their source-code origins to aid in optimization. This is done through the use of model trees to account for the multi-phase nature of workload performance and for statistical interactions between performance events.
