This article by Eric Siron, the author of Microsoft Hyper-V Cluster Design, presents holistic and specific methods to determine how well your system performs. It then guides you through balancing virtual machines across cluster nodes.
Now that we've covered how to design and plan your virtual machines, we're going to turn to the host's view of things. There are add-on and third-party tools that can perform automatic load balancing, but a failover cluster of Hyper-V Servers will only perform balancing in response to a failover event. Whether you'll use automated tools or not, you'll need to have an understanding of your host's abilities.
Balancing is not the entire story. Even if you have additional tools that can perform load balancing for you, you'll still need to keep abreast of the performance metrics of your cluster. As new virtual machines are added, your total capacity will be lessened and you'll want to know well in advance if you need to add hardware. Remember that your cluster is probably intended to survive the loss of at least one host without negatively impacting virtual machines, so just having a fully functional cluster with sufficient capacity may not be adequate.
There are two basic components to proper balancing. The first is being aware of what your hosts are capable of. The second is being aware of what they're doing. This article will work through a number of ways to satisfy these needs. You'll be introduced to the following concepts and activities:
- General system testing
- Disk I/O testing
- Memory testing
- Network testing
- Preferred and possible owners
This Article, by David Duncan and Christopher Liley, authors of Microsoft Dynamics GP 2013 Reporting, Second Edition, explains that, as a developer or consultant who has been assigned the task of filling user requests for reports should be aware that ultimately the very first question after deciding on the reporting tool is, "Where is my data and how do I get to it?"
Knowing where to begin is a critical first step in the development process. The aim of this article is to provide helpful tips for finding and locating data in the Dynamics GP 2013 ERP system and company databases. Although we'll discuss some reporting tools that do not require us to know the SQL database structure for Dynamics GP companies, it is still helpful to understand how GP stores its data.
In this article, we will discuss the following:
- Differences between the system database and company databases
- Conventions that are helpful to know and understand when it comes to Microsoft Dynamics GP 2013 data and how it is stored
- Using Resource Descriptions as a tool for finding data from within GP 2013
- Utilizing additional tools, such as the GP 2013 SDK and Support Debugging Tool, to find our data

In this article, Keith McCormick co-author of IBM SPSS Modeler Cookbook expresses pride in the fact that as a group of authors (Dean Abbott, Meta S. Brown, Tom Khabaza, and Scott R. Mutchler) that they have often provided the unexpected, the innovative, and boundary testing aspects of using Modeler everyday. Even the reviewers played a critical role in this. Two of the reviewers, Terry Taerum and Jesus Salcedo, made improvements to recipes and supplemented the recipes in the final days of the review process. All of the reviewers played a role in making the collection more innovative. Colin Shearer kindly observed in his Foreword:

In this article by Max De Wilde and Ruben Verborgh, the authors of the book Using OpenRefine, we dive deeper into dataset repair, demonstrating some of the more sophisticated data operations OpenRefine has to offer. OpenRefine (ex-Google Refine) is a powerful tool for working with messy data, cleaning it, transforming it from one format into another, extending it with web services, and linking it to databases like Freebase. The true power of OpenRefine only emerges when you dive into its more advanced features. This article will therefore shed light on the following:
- Recipe 1 – handling multi-valued cells
- Recipe 3 – clustering similar cells
Let's start with recipe 1.Read Advanced Data Operations in full
In this article by Brian Peiris, the author of the book Instant jQuery Flot Visual Data Analysis, we will understand that the axes are the most configurable parts of the chart. Flot gives you the ability to change the position, type, and colors of the axes. It also gives you full control of the ticks and labels on the axes, letting you adjust the number of ticks and alter the formatting. Axes also determine how the data is displayed; you can change the min and max settings to display only a part of the data on the chart and you can also transform the data in various ways.
The full documentation is available at https://github.com/flot/flot/blob/master/API.md#customizing-the-axes. We will take a look at some examples of the configuration options by creating a chart that has a logarithmic axis and another chart that includes multiple axes.Read Working with axes (Should know) in full
