Kurzbeschreibung

21. März 2014 Vmware Press Technology
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.

5.0 von 5 Sternen Klare Kaufempfehlung 9. April 2014
Format:Kindle Edition|Verifizierter Kauf
Als langjähriger VMware admin der sich mit dem Thema Netzwerk bisher nicht viel auseinander setzen musste, habe ich mir dieses Buch gekauft um meine Wissenslücken im Bereich VLAN, Teaming, und iSCSI Storage zu verkleinern.

Die Rechnung geht auf. Das Buch geht auf alle wesentlichen Aspekte des Übergangs zwischen physikalischem und virtuellem Netzwerk ein, natürlich mit starkem VMware-Bezug, schaut dabei aber auch oft über den Tellerrand hinaus. Ein guter Mix.

Die Informationen sind kompakt und gut begreiflich aufbereitet, auch für non-native speaker.

Die Funktionsweise der verschiedenen Optionen in den vSwitches werden sehr ausführlich erklärt, so dass auch erfahrene Administratoren noch das ein oder andere lernen können.

Abgerundet wird das Buch durch eine ganze Reihe von Design-Vorschlägen bei verschiedenen NIC Anzahlen und Konstellationen.

Ich kann dieses Buch neuen und alten VMware admins, sowie physikalischen Netzwerkadmins, die sich mit ihren VMware Kollegen eine gemeinsame Kommunikationsgrundlage schaffen wollen, nur empfehlen.

2.0 von 5 Sternen Disappointing 1. April 2014
Von Iron_Discipline - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Verifizierter Kauf
"The one-stop guide to modern networking for every VMware administrator, engineer, and architect". This book is an absolute homerun of a read for a junior network admin who landed his first job at a company leveraging vSphere. That said, I'm basing this review on the subject-matter depth I expected to glean from a book put out by VMware Press and authored by well-known blogger Chris Wahl. No disrespect to either of these parties but I feel this book missed the intended mark.

BLUF: There isn't much content here for a VMware Administrator. Even less for Engineer or Architect-level folks.
vCNS/vShield isn't mentioned. VXLANs aren't mentioned. SDN isn't mentioned, which I can understand since this is an Administrative guide, but NSX wasn't mentioned either. The scope of this book really is limited to just vSphere.

Chapters 1-6: Could have been cut and paste out of any networking 101 or Wikipedia article on networking basics. Other than passing mention of Nutanix's hyper-converged platform, these chapters offer little value to either a networking admin or a VMware admin.

Chapter 7 (How Virtual Switching Differs from Physical Switching): Useful for someone unfamiliar with VMware.

Chapters 8-10: Light on content, other than definitions of very basic concepts like what a VLAN is, what a VMkernel Port is, etc. At this point we're 135pgs into the book and we haven't touched a single thing that a low-level administrator (network or otherwise) can't rattle off in his sleep.
To say I'm disappointed is an understatement, but maybe we can still have some redemption in the second half of the book.

Chapter 11 (Lab Scenario): More definitions, a screen grab of the VLANs from UCS manager, and a picture of the summary tab of an ESXi 5.5 host, taken from the web client. Is this to prove that the authors have access to a server? I don't understand why they are wasting so many pages saying NOTHING!

Chapter 12 (Standard vSwitch Design): Importance of establishing naming conventions, and building a standard vSwitch that will carry all management and virtual machine traffic using 4 portgroups and 2 NICs. There is also mention of the VMkernel port req'd for NFS traffic. More on these topics later in the book though.

Chapter 13 (vDS design): Worthwhile chapter on how to build a distributed vSwitch.

Chapters 14 and 15 (iSCSI considerations): Definitions and basic configuration. Nothing new here.

Chapters 16 & 17 (NFS overview): Good chapters on how VMware handles NFS traffic and how to do a basic configuration.

Chapter 18 (additional vSwitch Design Scenarios): vSwitch design suggestions for hosts that have more than 2 physical NICs.

Chapter 19 (Multi-NIC vMotion Architecture): Interesting chapter on a concept I don't often think about.

End of the book.

5.0 von 5 Sternen An excellent resource for VMware admins doing networking, or networks admins working with VMware 4. April 2014
Von Sam McGeown - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I recently got my hands on a copy of Chris Wahl and Steve Pantol’s Networking for VMware Administrators and was very keen to read it – especially given the reputation of the authors. I came to the book as someone who is at CCNA level (although now expired) and someone who regularly designs complex VMware networks using standard and distributed switches. I would class myself as having a fairly decent understanding of networking, though not a networking specialist.

The book starts out at from a really basic level explaining OSI, what a protocol is etc. and builds on the foundation set out as it progresses. Part I of the book gives are really good explanation of not only the basics of networking, but a lot of the “why” as well. If you’ve done CCNA level networking exams then you will know most of this stuff – but it’s always good to refresh, and maybe cover any gaps.

Part II of the book translates the foundations set out in Part I into the virtual world and takes you through the similarities and differences with between virtual and physical. It gives a good overview of the vSphere Standard Switch (VSS) and vSphere Distributed Switch (vDS) and even has a chapter on the Cisco 1000v. One of the really useful parts of the book are the lab examples and designs, which takes you though the design process and considerations to get to the solution.

Part III is an excellent and detailed section on storage networking covering networks for iSCSI and NFS, and design and configuration of both – with use cases. If you’ve not had much experience with these protocols in a production environment then this section will be a fantastic resource.

Part IV is labelled “Other Design Scenarios” and contains a lot of reference storage design examples based on numbers of NICs available in a host and whether that includes IP based storage – again, another really useful resource.

I really like the writing style that the authors have used, there’s enough humour and anecdotal/real world reference to drag it out of the “pure technical” category and help engage the reader, without detracting from the sheer volume of information that’s contained in the book.

Throughout the book there are lots of clear diagrams which help to explain and expand on the text, and again improve the readability of the book.

I would recommend this to any VMware administrator with responsibility for designing and managing VMware networking – and also perhaps some network administrators who work with a VMware team. It will give insight into how the two relate to each other. I’d probably even recommend it to storage administrators who manage iSCSI and NFS storage networks with VMware.

There are parts of the book that were really basic and, I have to confess, I skipped over – but as I mentioned before I have a fair amount of networking experience. But there is also enough meat on the bones to make the book worthwhile and a great resource for your bookshelf.

Networking for VMware Administrators is available on Amazon in both paper and kindle versions:

* Full disclosure – I was sent a copy of the book for review, I will receive no reward for this and the review is my own honest thoughts and opinion.

5.0 von 5 Sternen Excellent addition to any VMware professional's library. Get it! 7. April 2014
Von Richard R - Veröffentlicht auf Amazon.com
Format:Taschenbuch
Being a consultant who works daily with VMware technologies, yet lacking a background in networking, I had been eagerly anticipating the release of this book for a while. Networking was always something that ‘someone else’ did in the past but due to the convergence of data centre skills this attitude really doesn’t cut it anymore. The timing is highly appropriate and I have been a fan of Chris Wahl’s material for a while so was very happy to get my hands on a copy.
First things first, the biggest achievement of this book was to hold my attention throughout its entire duration. Even when covering some relatively non-glamorous, yet essential, topics it did not, at any point become too dry and make me lose interest. The authors have a slightly humorous yet non-flippant style that keeps you reading and entertained yet doesn’t skimp on the content.
In terms of technical detail the most interesting part for me by far were the use cases. The authors talk you through multiple different permutations of network adapters and port requirements across both vSphere standard and distributed switches, in each case allowing you to put together a resilient and performant design. I’ve been reading about these things for years now but rarely have I seen the info collated together so concisely in one place with proper justifications that actually make sense. I now confidently feel I could design vSphere host networking in most common configurations and make informed choices, justifying their selection. The other one that was great for me was the description of the different options for networking to NFS storage and getting around the lack of multipathing. I was faced with this issue with a client last year and literally spent countless hours combing google for good answers on this, turning up very little that made sense, but finally now it was summarised for me in a handful of pages. Thirdly it has an excellent section on multi-nic vmotion.
If I could make some suggestions for what I would have liked to see then maybe it would have been good to see some highly detailed packet-walks for traffic between VMs within/between hosts across the physical network and the processes that take place. In addition I was surprised to not see at least a one-pager at the end about network virtualisation and the future of virtual data centre networking, although I realise this was not within the scope of the book. Having said that I used this text as a primer before hitting an NSX bootcamp at VMware and it really helped me prepare for/survive the, rather intense, training. Overall I’m very impressed with this book and it’s definitely one of the best that I have in my library now. Highly recommended and I’m sure anyone who works in this field and knows the quality of the authors will be buying anyway. I’m off to start my second read…(this doesn't happen often)

5.0 von 5 Sternen Great book for anyone that manages a VMware environment. 31. März 2014
Von Kellan Damm - Veröffentlicht auf Amazon.com
Format:Kindle Edition|Verifizierter Kauf
This book is great as a refresher or as a starting point for VMware admins. The content was well rounded and they got to the point in a clear and concise manner. I also enjoyed that there was humor involved. My only complaint about this book is that everything was shown in the web client. It would have been great to see correlating esxcli commands but there was only one instance and that was creating a vSwitch. But the authors do state that this was a not to be used as a learning tool so I forgive them.

5.0 von 5 Sternen Excellent resource for new and old VMware Administrators 14. April 2014
Von Ather Beg - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I always wondered why there is no book that specifically focusses on VMware networking, given its importance when it comes to deployment and maintenance of a stable virtual platform. No need for me to think that any more as this book is all that!

Given that the breakdown of parts and chapters of this book are available everywhere, I won’t bore you with that detail. Instead, I’ll just give you my thoughts on the different parts and why I think this is one of the must have books (if you’re into these sort of books, of course!)

First part consists of 6 chapters and goes through the basics of Physical Networking. If you are new to networking, this is a good place to start as it covers all the prerequisite knowledge that one must have to understand the rest of the book. It also serves as a refresher for people who are experienced in networking but for whom, it’s not their day-to-day job. The conversation starts with light-hearted layman level discussion of how networks came into existence, then slowly builds up to explain the different layers and finishes with a discussion on “Converged Infrastructure”. I think, this is required knowledge to appreciate the subtle differences between physical and virtual networking. Armed with that knowledge, one is ready to delve into the VMware side of things.

Second part consists of 7 chapters and discusses virtual networking in a vSphere environment. The first few chapters discuss the two main types of networking switches (“Standard” and “Distributed”), where they match or differ as compared to physical switches and the configuration options available for both. Throughout those chapters, there is also a brief discussion on the various configuration options and where certain options might be applicable (or not). Things are explained with the help of a “Lab Scenario”, which uses a Cisco UCS environment as an example. The last two chapters, discuss designing a network environment around a Standard or Distributed switch. It’s nice to see a book still discussing designing around a Standard switch as not everyone has Enterprise Plus licensing or might have a mixture within their environment.

Third part consists of four chapters and focusses on the two types of IP Storage supported by vSphere environments: iSCSI and NFS. There are two chapters for each type, discussing use cases and then going on to design considerations and configuration. For iSCSI, there is quite a bit of detail in terms of the components that make up iSCSI, Authentication, Initiators/Targets, Adapters, Jumbo Frames etc. That is followed by a chapter on a design using iSCSI storage. NFS discussion carries on with the same theme but it being NFS, it’s more about exports, daemons and mount points etc. In the same way as iSCSI, this chapter is followed by another, discussing a design based on NFS storage. In both cases, the chapters cover the configuration steps as well so one can see practically how those steps are carried out, to achieve that particular configuration.

Finally, there is part four, consisting of just two chapters. The first one covers some vSwitch Design Scenarios. This chapter covers pretty much all the different configurations, big or small, that one would probably encounter in the real world. If by chance a use case is missed, I am sure one can tackle that easily, having absorbed all this information. The second chapter discusses “Multi-NIC vMotion Architecture” and design considerations. It also quite helpfully discusses how a combination of NIOC (Network I/O Control) and egress traffic shaping can protect such an environment from drowning out a particular destination host. Finally, it goes into how to properly configure such a setup.

The whole book is written in a light-hearted conversational manner and doesn’t feel like heavy reading at all – unlike typical networking books. Like I mentioned before, all topics are accompanied with a healthy dose of discussion on why certain options are suitable or not and with plenty of screenshots too! I also discovered the word “schlep” (something I doubt I’ll find in any other technical book) and that “warm and fuzzies” are pretty important when it comes to VMware networking.

For people starting with VMware products, this is a must have as it will give them a solid foundation of networking concepts and how to configure vSphere networking properly. It also does a great job of bridging the gap that exists for people coming from traditional physical networking backgrounds.

Highly recommended!
