The process of learning how to subnet IP addresses begins with understanding binary numbers and decimal conversions along with the basic structure of IPv4 addresses. This paper focuses on the mathematics of binary numbering and IP address structure.

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. Examples include how to expand storage capacity on the fly using LVM and resize2fs, and how to migrate data from local storage to a storage area network (SAN) without downtime using pvmove.

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.

Network Functions Virtualization (NFV) is gaining momentum along with Software-Defined Networking (SDN). This paper examines the history of NFV and explores the prospects for networking to gradually evolve from a hardware-centric approach to a software-driven model. It concludes with an examination of future market implications and how NFV can help organizations to achieve their goals.

Many people believe that cloud computing requires server (or desktop) virtualization. But does it? We will look at using virtualization without cloud computing, cloud computing without virtualization, and then look at using both together. In each case, we'll look at where each deployment might be most useful, some use cases for it and some limitations.

Nasser El-Batal will walk you through the most useful, recognized, and mandated ITSM best practices in the industry: TOGAF, COBIT and ITIL®. He will highlight the benefits of integrating them into a single implementation program to avoid project disaster. Discussions are focused on "Getting Your House in Order" and how to establish your own organization-specific business transformation program, while increasing your organization maturity.

After a review of Software-Defined Networking (SDN) and its close cousin Network Functions Virtualization (NFV), this white paper addresses three main deployment scenarios: SDN without deploying cloud computing, cloud computing without deploying SDN, and deploying cloud computing in conjunction with SDN. We'll look at use cases, when the approach makes sense, and any applicable limitations.

The Open Group Architectural Framework (TOGAF) provides a structure for describing all transformational work within an enterprise. While TOGAF focuses on the role of an enterprise's architects, it also very much addresses the space in which business analysts (BAs) play. This can lead to role confusion, blurred deliverables, and duplicate work. In this one-hour webinar, business analysis expert and Global Knowledge instructor Adam McClellan will focus on those parts of TOGAF in which the business analyst is typically the most active, and he will outline how the analyst's work contributes to the broader architecture. He will also provide perspective for architects who work with BAs and for BAs interested in the architecture disciplines.

In 2013, VMware announced VMware Virtual SAN (VSAN), which is VMware's native version of Software Defined Storage (SDS). It is simple, easy to setup and managed by user-defined policies. This paper explains VSAN, its basic requirements and how it works.

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.
