VMware vSphere 6.5 Host Resources Deep Dive

If you are actively managing VMware environments with workloads that have high performance needs (such as all of the virtualized SQL Servers that we work on), this new book called VMware vSphere 6.5 Host Resources Deep Dive, written by Frank Denneman and Niels Hagoort, is a must read book! Designed for VMware-oriented system architects, this book walks the reader through each layer of host resource allocation and management in a way that no other book has ever accomplished.This book redefined the phrase “deep dive”, and I’m taking a lot of notes for future authoring and presentations. The depth of content is unparalleled in tech authoring.Topic sections such as CPU, memory, storage, and networking, the four main areas of resource management on any virtualization host, are presented. Anyone can talk about these settings in general, but the advanced VCDX-level topics are covered in incredible depth. We work with a lot of advanced virtualized SQL Server VMs, and significant discussions from this book for performance tuning these SQL Servers include:Advanced vNUMA balancing and optimizationCPU core counts versus clock speedvNUMA memory speeds and non-local memory accessClearing up misconceptions about vSphere Balanced Power ManagementQueues and resource allocationsGo get this book – NOW! It’s a must read, and read it twice. No, three times. Then give the book to colleagues who can benefit. I’ve got two copies on my desk right now, and know who these will be sent to after I’m done re-reading them!

After reading the various iterations of the vSphere Clustering Deep Dive series, my expectations for this book were high. I'm happy to say that I was not disappointed. The VMware vSphere 6.5 Host Resources Deep Dive provides so much technical detail that it can make your head spin. Thankfully Frank and Niels has done an awesome job of presenting deep technical content in a manner that makes it a joy to read.Clear, concise and to the point. This is a book I'll return to time and time again, as there is simply no way you can read this once, and be done with it. There is simply to much information in here to digest in a single read through. Don't be fooled by the VMware vSphere mention in the title, even if you don't work exclusively with VMware vSphere environments, this book is still an invaluable resource for anyone working with datacenter technologies.Simply put: Buy this book.

This book has level of details that you will not find anywhere else, at least not from a single source. The writers provided in depth background on each topic before diving in to it. Having a degree in Computer Engineering, I feel this can easily serve as a text book on inner workings of a modern server. It navigates through CPU to Memory to Storage and Network, and provides all the information needed to run the virtual workload optimally. How to right size the VM, how to make sure you are not allocating resources that would adversely impact the performance etc.

If you spend a significant amount of your professional life managing vSphere environments, you'll want to pick up this technical reference. The organization of this book is remarkable; there's no wasted time or text, just a immediate dive into great technical information. Even if you've been a vSphere user for a long time, you'll learn much about new features in ESXi 6.5.I recommend treating this as a reference book and not a novel. Your brain would melt if you tried to read this book straight-through. At least mine did.

If you are even remotely interested in Virtualization, this is the book for you. Time to get on your scuba gear, or fire up the mini sub, and get ready to plummet down to the bottom of the Mariana Trench of Host Resources. Someday, when I grow up, I hope to be HALF as knowledgable about this subject as Frank and Niels are. Get this book. Get it yesterday, or even two days ago, so that it arrives today.

Only 5 chapters in but feel compelled to give a quick review/praise of this book. This book (and its authors) are great. It is not meant for the uninitiated both from a hardware perspective or VMware perspective. That said, if you're interested and somewhat knowledgeable of hardware overall, this book may connect some dots for you. I can't recommend this book enough and it's a great price for the information within!

This book is an immediate MUST HAVE for anyone supporting or administering VMware vSphere. It has everything you need to know when it comes to optimizing your vSphere environment....CPU, memory, storage (including vSAN), networking and more! I am a VMware Certified Design Expert (VCDX) and I keep this book with me at all times. It has literally become a tool for me. I have not put it down since I purchased it. Get this book!

This is a must have book for anyone wanting to really understand the inner workings of their ESXi Hosts. I'm studying for my VCDX and found that the level of depth has helped raise my confidence in terms of defending my design with concrete evidence and knowledge. Frank and Niels are clearly experts in their craft and it shows in this book.

I've been waiting for this book for a while, and boy, I was not disappointed.There is a wealth of information in this book, and will serve as a reference for a very long time to come.If you're a vSphere Administrator and work with the product day-to-day then this will be an essential tool in your arsenal. It will challenge a number of "best practices", ie something you've always done but can't remember the reasons for it. Do you set your ESXi hosts to the High Performance power setting? If so, why? Is it better to buy servers with 256GB or 384GB of RAM?The book covers the main pillars of host resources such as compute, networking and storage. Leading technologies such asVMware vSAN and NSX are covered, and will give you the information you need to ensure your implementation goes as smooth as possible.This book is a weighty tomb of information. It is by no means a quick read, but I'm confident it'll be something you'll go back to again and again.

A very good deep and detailed explanation on why the esx works the way it does, the chips architecture and how to squeeze performance out of any system. If you do or consider NFV, very important resource on the factors that make a difference and the tradeoffs of every decision. Great detail, very good content, and coming from the authorities at vmware. Also a good price and given todays transient world of products and versions, spot on pricing and timing.

I work with ESXi 8 hours a day but this is way beyond what I need to know for my day to day. Maybe useful if you are a software engineer for VMware!

Everything you could possibly want to know about hardware when it comes to virtualisation. Don't throw money at the problem, optimise it!

Wer wirklich verstehen will, was in VMwares Hypervisor ESXi 6.5, der die Basis für vSphere bildet, abgeht, der kommt an diesem Buch nicht vorbei.Frank Denneman hat hier zusammen mit Niels Hagoort ein Referenzwerk abgeliefert, das seinesgleichen sucht. Alle performancerelevanten Bereiche von ESXi werden eingehend und in beeindruckender technischen Tiefe beleuchtet und Handlungsempfehlungen zur optimalen Konfiguration werden ebenfalls erteilt.Dank dieses Buches kann man einiges - nicht nur zu VMwares Hypervisor - lernen, u.a. zu aktuellen CPU- und Speichertechniken.Das Buch ist uneingeschränkt empfehlenswert!
