Wi-Fi networks have been misunderstood by much of the IT community since their inception. Even the reasons for this misunderstanding are kind of hard to understand. The result has been that myths about 802.11 (better known as Wi-Fi) networks have grown almost as fast as the technology itself. In this web seminar, we'll examine 11 common Wi-Fi myths and explore ways to use correct information to make your networks scalable, secure and satisfying for your users.

The flexibility, reduced cost, and mobility of cloud computing have made the concept a hot topic. Before implementing this method of computing, however, it is important to consider the security of the "cloud." During this webinar, we will help you understand some of the risks and benefits of cloud computing so you can decide if it is the right solution for you.

In this webinar, the first of two based on our Cybersecurity Foundations course, you will examine the following topics: verifying users and what they can access, ways a user can be validated to computer and network resources, how cryptography is used to protect data, symmetric and asymmetric encryption and hashes.

Here are seven tips for working with vSphere, including: Logging in via Command Line, dealing with connection problems using ssh to an ESXi host; network performance issues; possible storage problems; Log Files to View in vSphere ESXi 5; network performance troubleshooting; migrating to a virtual machine using VMotion.

This vSphere Essentials white paper will give you a basic understanding of some of the concerns or planning points to consider as you get ready to deploy vSphere in your organization. This is a glimpse into some of the essential things to consider for implementing vSphere. This will focus on some of the basics that vSphere administrators run into when installing the latest features and not realizing they still have some older versions implemented.

This white paper has three main goals. The first is to generate a better understanding of the cloud in both the business and IT communities. The second is to describe the major components of vCloud and the virtual datacenters they provide. The third is help businesses visualize and understand how vClouds could be beneficial in addressing their specific IT needs.

Resource Pools are often misunderstood, disliked, and untrusted by vSphere Administrators. However, resource pools can be very useful tools for administrators who want to configure resource management without having to individually configure each VM. This leads to the administrator’s desire to explore the proper usage of resource pools.

With the growth of bring your own device (BYOD) and mobility, users are increasingly asking for computing anywhere from any device at any time. Users now expect productivity on the go with a desktop that can be freely accessed and secure. We're no longer a society that sits at a desk to be productive. The VMware Horizon Suite allows the datacenter administrators to satisfy the accelerated mobility needs of the workforce while still maintaining an IT solution that is easily managed and secure.

VMware vCloud Director fashions the provisioning of the software-defined datacenter layer to allow for a full virtual datacenter deployment within a short period of time. A vCloud consists of many layers and can quickly become a complex architecture. Before any deployment, requirements should be defined so that the vCloud can be designed to offer those services needed. It is imperative to understand the many components of vCloud, how each vCloud construct fits, which allocation models are available, and what network options can be chosen.

You have spent money on software and hardware, implemented best practices, and believe you are secure, right? You may have overlooked the weakest link: your employee. Many breaches occur as a result of an employee mistakenly clicking on a link or visiting a site that allows a virus to be unknowingly downloaded, giving hackers access to your network. Today, a well-trained workforce is a necessity and may even be your most important cybersecurity tool. In this webinar, security expert David Willson will discuss how many breaches have occurred and are occurring, the tools and techniques hackers use to trick employees into clicking on links or opening attachments, and how to prevent such behavior.

vSphere 5.5 is now available with myriad small improvements such as a faster Web Client, LACP, Autoscale and higher configuration maximums. In addition, there are changes coming such as VSAN, which may be ground-breaking in regard to VM storage of the future. Since the release of vSphere 5.5, they have not yet announced a change to the blueprint for the test. That being the case, I will say, for now, that the VCP-510 test should remain unchanged as well. My goal here is not to reeducate you on everything that you need to know for the test; instead, it is to point out the few changes that might apply in your company or organization.

If you have been working with vSphere 5.1 or 5.5 lately, you have undoubtedly noticed that the latest features such as XvMotion and vSphere Replication are only available on the Web Client. This cheat sheet for the new Web Client includes instructions for configuring VMs, networking, storage, resource settings, cluster settings, permissions, and many other settings.

The technologies examined reduce operational expenses (OpEx), not capital expenses (CapEx) that has traditionally been the focus of virtualization. Many companies implemented virtualization with the goal of saving money in the form of fewer servers to buy with a side benefit of reducing the footprint of the servers and lowering the required power and cooling. Most of the savings were in capital, but do not expect the same with many of the technologies listed here, because some may even require some additional capital expenditures, at least for software, in order to save on the day-to-day operations of IT. The bigger cost in running an IT department is in the OpEx category anyway, so savings there are recurring.

In this seminar, discover how OpenStack can simplify your cloud infrastructure management. Experts from Red Hat, the leading contributor to the OpenStack project, will fill you in on how organizations have solved problems and increased business value with open-source cloud technology. They will also give you a peek into the future of Red Hat OpenStack and reveal how Red Hat training and certification can ensure the success of your cloud deployment.

Often, we don't have time to learn the reasons behind the standards we use. But learning what instigated a standard goes a long way toward not only understanding its importance, but also more easily and effectively applying it in your workplace. In this hour-long webinar, Global Knowledge instructor Keith Sorn will discuss common networking standards and explain how they were determined and why they are relevant. He will fill you in on things like why it's important to use proper color-coding standards when making cable and why the length limitations on wired cable are essential. He will also explain new standards, such as power over fiber.

The Logical Volume Manager (LVM) is a powerful tool for managing storage on Linux servers. This video provides an overview of how LVM works and explores several ways that LVM makes storage management easier and more flexible.

VMware Horizon 6 was announced in April and began shipping in June 2014, bringing a more unified suite delivering more integration with infrastructure and cloud products and more simplicity for all devices. Along with the numerous updates across the Horizon suite, VMware has transitioned to a more traditional product licensing hierarchy. This paper explores the new licensing model and provides an overview of the new features associated with VMware Horizon 6.

With VMware's recent release of the Horizon Suite (specifically View 6), VMware has taken the performance and usability features and put them all under the Blast moniker. This category of features is grouped from a marketing perspective but will retain their technical terms in the documentation, similar to how the term vSphere encompasses both ESXi and vCenter. Learn about the various features of the components that comprise the Blast family, including a brief discussion of what they are, improvements in version 6, and any notes or requirements for implementation.

One of the advantages of vSphere is that you can move a virtual machine from one location to another, across servers, storage locations-even data centers. Physical servers don't have that ability and that can have many implications for disaster recovery, availability, and so forth. This white paper explains why migrations are useful, the methods that vSphere makes available for you to manually move a virtual machine (VM), and how vSphere can automate the process for you in various scenarios.

There are two types of virtual switches available using vSphere, the vSphere Standard Switch and the vSphere Distributed Switch. The vSphere Standard Switch (vSwitch or vSS) resides in and is manually configured and administered on each ESXi host. The vSphere Distributed Switch (dvSwitch or vDS) provides similar functionality but is centralized to vCenter Server and is more featured. This white paper will cover the vDS architecture as well as an overview of many of the different features that are exclusive to the vSphere Distributed Switch.

Virtual storage area network (VSAN) and VMware View can offer cost savings and performance benefits compared to traditional SAN implementations for virtual desktop infrastructure (VDI). If you are starting a new desktop virtualization project, it would be wise for you to take the time to explore your options and compare VSAN to other options.
