High Availability Clusters in VMware vSphere without Sacrificing Features or Flexibility
This paper explains the challenges of moving important applications from traditional physical servers to virtualized environments, such as VMware vSphere in order to take advantage of key benefits such as configuration flexibility, data and application mobility, and efficient use of IT resources and highlights six key facts you should know about HA protection in VMware vSphere environments that can save you money.

Many large enterprises are moving important applications from traditional physical servers to virtualized environments, such as VMware vSphere in order to take advantage of key benefits such as configuration flexibility, data and application mobility, and efficient use of IT resources.

Realizing these benefits with business critical applications, such as SQL Server or SAP can pose several challenges. Because these applications need high availability and disaster recovery protection, the move to a virtual environment can mean adding cost and complexity and limiting the use of important VMware features. This paper explains these challenges and highlights six key facts you should know about HA protection in VMware vSphere environments that can save you money.

Application & Desktop Delivery for Dummies
In this book, you learn how solutions, such as Parallels Remote Application Server (RAS), replace traditional application deployment with on-demand application delivery, and why it's right for your organization.
Applications are essential to the businesses and organizations of all sizes and in all industries. End-users need to have continuous and reliable access to their applications whether working in the office or remotely, at any time of the day or night, and from any device. With the advent of cloud computing, office desktops with installed applications (that had to be constantly updated) have become a thing of the past — application streaming, virtual desktop infrastructure (VDI), and hosted applications are the future (and the present, for that matter). Application virtualization is an easy way to manage, distribute, and maintain business applications. Virtualized applications run on a server, while end-users view and interact with their applications over a network via a remote display protocol. Remote applications can be completely integrated with the user’s desktop so that they appear and behave like local applications. Today, you can dynamically publish applications to remote users in several ways. The server-based operating system (OS) instances that run remote applications can be shared with other users (a terminal services desktop), or the application can be running on its own OS instance on the server (a VDI desktop).

vSphere Troubleshooting Guide
Troubleshooting complex virtualization technology is something all VMware users will have to face at some point. It requires an understanding of how various components fit together and finding a place to start is not easy. Thankfully, VMware vExpert Ryan Birk is here to help with this eBook preparing you for any problems you may encounter along the way.

This eBook explains how to identify problems with vSphere and how to solve them. Before we begin, we need to start off with an introduction to a few things that will make life easier. We’ll start with a troubleshooting methodology and how to gather logs. After that, we’ll break this eBook into the following sections: Installation, Virtual Machines, Networking, Storage, vCenter/ESXi and Clustering.

ESXi and vSphere problems arise from many different places, but they generally fall into one of these categories: Hardware issues, Resource contention, Network attacks, Software bugs, and Configuration problems.

A typical troubleshooting process contains several tasks: 1. Define the problem and gather information. 2. Identify what is causing the problem. 3. Fix the problem, implement a fix.

One of the first things you should try to do when experiencing a problem with a host, is try to reproduce the issue. If you can find a way to reproduce it, you have a great way to validate that the issue is resolved when you do fix it. It can be helpful as well to take a benchmark of your systems before they are implemented into a production environment. If you know HOW they should be running, it’s easier to pinpoint a problem.

You should decide if it’s best to work from a “Top Down” or “Bottom Up” approach to determine the root cause. Guest OS Level issues typically cause a large amount of problems. Let’s face it, some of the applications we use are not perfect. They get the job done but they utilize a lot of memory doing it.

In terms of virtual machine level issues, is it possible that you could have a limit or share value that’s misconfigured? At the ESXi Host Level, you could need additional resources. It’s hard to believe sometimes, but you might need another host to help with load!

Once you have identified the root cause, you should assess the impact of the problem on your day to day operations. When and what type of fix should you implement? A short-term one or a long-term solution? Assess the impact of your solution on daily operations. Short-term solution: Implement a quick workaround. Long-term solution: Reconfiguration of a virtual machine or host.

Now that the basics have been covered, download the eBook to discover how to put this theory into practice!

Mastering vSphere – Best Practices, Optimizing Configurations & More
Do you regularly work with vSphere? If so, this free eBook is for you. Learn how to leverage best practices for the most popular features contained within the vSphere platform and boost your productivity using tips and tricks learnt direct from an experienced VMware trainer and highly qualified professional. In this eBook, vExpert Ryan Birk shows you how to master: Advanced Deployment Scenarios using Auto-Deploy Shared Storage Performance Monitoring and Troubleshooting Host Network configurati

If you’re here to gather some of the best practices surrounding vSphere, you’ve come to the right place! Mastering vSphere: Best Practices, Optimizing Configurations & More, the free eBook authored by me, Ryan Birk, is the product of many years working with vSphere as well as teaching others in a professional capacity. In my extensive career as a VMware consultant and teacher (I’m a VMware Certified Instructor) I have worked with people of all competence levels and been asked hundreds - if not thousands - of questions on vSphere. I was approached to write this eBook to put that experience to use to help people currently working with vSphere step up their game and reach that next level. As such, this eBook assumes readers already have a basic understanding of vSphere and will cover the best practices for four key aspects of any vSphere environment.

The best practices covered here will focus largely on management and configuration solutions so should remain relevant for quite some time. However, with that said, things are constantly changing in IT, so I would always recommend obtaining the most up-to-date information from VMware KBs and official documentation especially regarding specific versions of tools and software updates. This eBook is divided into several sections, and although I would advise reading the whole eBook as most elements relate to others, you might want to just focus on a certain area you’re having trouble with. If so, jump to the section you want read about.

Before we begin, I want to note that in a VMware environment, it’s always best to try to keep things simple. Far too often I have seen environments be thrown off the tracks by trying to do too much at once. I try to live by the mentality of “keeping your environment boring” – in other words, keeping your host configurations the same, storage configurations the same and network configurations the same. I don’t mean duplicate IP addresses, but the hosts need identical port groups, access to the same storage networks, etc. Consistency is the name of the game and is key to solving unexpected problems down the line. Furthermore, it enables smooth scalability - when you move from a single host configuration to a cluster configuration, having the same configurations will make live migrations and high availability far easier to configure without having to significantly re-work the entire infrastructure. Now the scene has been set, let’s get started!

How Data Temperature Drives Data Placement Decisions and What to Do About It
In this white paper, learn (1) how the relative proportion of hot, warm, and cooler data changes over time, (2) new machine learning (ML) techniques that sense the cooling temperature of data throughout its half-life, and (3) the role of artificial intelligence (AI) in migrating data to the most cost-effective tier.

The emphasis on fast flash technology concentrates much attention on hot, frequently accessed data. However, budget pressures preclude consuming such premium-priced capacity when the access frequency diminishes. Yet many organizations do just that, unable to migrate effectively to lower cost secondary storage on a regular basis.

PowerCLI - The Aspiring Automator's Guide
Automation is awesome but don't just settle for using other people's scripts. Learn how to create your own scripts and take your vSphere automation game to the next level! Written by VMware vExpert Xavier Avrillier, this free eBook presents a use-case approach to learning how to automate tasks in vSphere environments using PowerCLI. We start by covering the basics of installation, set up, and an overview of PowerCLI terms. From there we move into scripting logic and script building with step-by

Scripting and PowerCLI are words that most people working with VMware products know pretty well and have used once or twice. Everyone knows that scripting and automation are great assests to have in your toolbox. The problem usually is that getting into scripting appears daunting to many people who feel like the learning curve is just too steep, and they usually don't know where to start. The good thing is you don't need to learn everything straight away to start working with PowerShell and PowerCLI. Once you have the basics down and have your curiosity tickled, you’ll learn what you need as you go, a lot faster than you thought you would!

ABOUT POWERCLI

Let's get to know PowerCLI a little better before we start getting our hands dirty in the command prompt. If you are reading this you probably already know what PowerCLI is about or have a vague idea of it, but it’s fine you don’t. After a while working with it, it becomes second nature, and you won't be able to imagine life without it anymore! Thanks to VMware's drive to push automation, the product's integration with all of their components has significantly improved over the years, and it has now become a critical part of their ecosystem.

WHAT IS PowerCLI?

Contrary to what many believe, PowerCLI is not in fact a stand-alone software but rather a command-line and scripting tool built on Windows PowerShell for managing and automating vSphere environments. It used to be distributed as an executable file to install on a workstation. Previously, an icon was generated that would essentially launch PowerShell and load the PowerCLI snap-ins in the session. This behavior changed back in version 6.5.1 when the executable file was removed and replaced by a suite of PowerShell modules to install from within the prompt itself. This new deployment method is preferred because these modules are now part of Microsoft’s Official PowerShell Gallery. 7 These modules provide the means to interact with the components of a VMware environment and offer more than 600 cmdlets! The below command returns a full list of VMware-Associated Cmdlets!

Why Network Verification Requires a Mathematical Model
Learn how verification can be used in key IT processes and workflows, why a mathematical model is required and how it works; as well as example use cases from the Forward Enterprise platform.
Network verification is a rapidly emerging technology that is a key part of Intent Based Networking (IBN). Verification can help avoid outages, facilitate compliance processes and accelerate change windows. Full-feature verification solutions require an underlying mathematical model of network behavior to analyze and reason about policy objectives and network designs. A mathematical model, as opposed to monitoring or testing live traffic, can perform exhaustive and definitive analysis of network implementations and behavior, including proving network isolation or security rules.

In this paper, we will describe how verification can be used in key IT processes and workflows, why a mathematical model is required and how it works, as well as example use cases from the Forward Enterprise platform. This will also clarify what requirements a mathematical model must meet and how to evaluate alternative products.
