Description
The one-stop guide to modern networking for every VMware (R) administrator, engineer, and architect
Now that virtualization has blurred the lines between networking and servers, many VMware specialists need a stronger understanding of networks than they may have gained in earlier IT roles. Networking for VMware Administrators fills this crucial knowledge gap. Writing for VMware professionals, Christopher Wahl and Steve Pantol illuminate the core concepts of modern networking, and show how to apply them in designing, configuring, and troubleshooting any virtualized network environment.
Drawing on their extensive experience with a wide range of virtual network environments, the authors address physical networking, switching, storage networking, and several leading virtualization scenarios, including converged infrastructure.
Teaching through relevant examples, they focus on foundational concepts and features that will be valuable for years to come. To support rapid learning and mastery, they present clear learning objectives, questions, problems, a complete glossary, and extensive up-to-date references.
Coverage includes:
* The absolute basics: network models, layers, and interfaces, and why they matter
* Building networks that are less complex, more modular, and fully interoperable
* Improving your virtual network stack: tips, tricks, and techniques for avoiding common pitfalls
* Collaborating more effectively with network and storage professionals
* Understanding Ethernet, Advanced Layer 2, Layer 3, and modern converged infrastructure
* Mastering virtual switching and understanding how it differs from physical switching
* Designing and operating vSphere standard and distributed switching
* Working with third-party switches, including Cisco Nexus 1000V
* Creating powerful, resilient virtual networks to handle critical storage network traffic
* Deploying rackmount servers with 1 Gb and 10 Gb Ethernet
* Virtualizing blade servers with converged traffic and virtual NICs
Christopher Wahl has acquired well over a decade of IT experience in enterprise infrastructure design, implementation, and administration. He has provided architectural and engineering expertise in a variety of virtualization, data center, and private cloud based engagements while working with high performance technical teams in tiered data center environments. He currently holds the title of Senior Technical Architect at Ahead, a consulting firm based out of Chicago.
Steve Pantol has spent the last 14 years wearing various technical hats, with the last seven or so focused on assorted VMware technologies. He is a Senior Technical Architect at Ahead, working to build better datacenters and drive adoption of cloud technologies.

Chris Wahl has acquired more than a decade of IT experience in enterprise infrastructure design, implementation, and administration. He has provided architectural and engineering expertise in a variety of virtualization, data center, and private cloud-based engagements while working with high performance technical teams in tiered data center environments. He currently holds the title of Senior Technical Architect at Ahead, a consulting firm based out of Chicago. Chris holds well over 30 active industry certifications, including the rare VMware Certified Design Expert (VCDX #104), and is a recognized VMware vExpert. He also works to give back to the community as both an active "Master" user and moderator of the VMware Technology Network (VMTN) and as a Leader of the Chicago VMware User Group (VMUG). As an independent blogger for the award winning "Wahl Network," Chris focuses on creating content that revolves around virtualization, converged infrastructure, and evangelizing products and services that benefit the technology community. Over the past several years, he has published hundreds of articles and was voted the "Favorite Independent Blogger" by vSphere-Land for 2012. Chris also travels globally to speak at industry events, provide subject matter expertise, and offer perspectives as a technical analyst.
Steve Pantol has spent the last 14 years wearing various technical hats, with the last seven or so focused on assorted VMware technologies. He holds numerous technical certifications and is working toward VCDX-if only to stop Wahl from lording it over him. He is a Senior Technical Architect at Ahead, working to build better data centers and drive adoption of cloud technologies.
