A new, very interesting whitepaper from Runecast which focuses on Reducing operational complexity. today's Datacenter environments aren't getting any simplicity. In fact, it's rather the other way around. More and more complex.
You can download the FREE Whitepaper here.
7 Areas which cause pain for the infrastructure teams:
- Technology complexity
- Aggregated rate of change
- Volume of Knowledge Base articles
- Ad-hoc changes from troubleshooting
- Long time to resolution
- Reactive fault resolution
Most times, when an outage occurs in a well-managed data center, the cause is a fault that was known to the system vendor. It might be a bug that is patched in a later software release or it might be a default configuration that doesn’t work for a specific combination of components. The engineer who is resolving the fault will use Google to discover the known issue and apply its known resolution. There are thousands of known issues with various combinations of components.

Essential Virtual SAN (VSAN): Administrator's Guide to VMware Virtual SAN – Cormac Hogan (@cormacjhogan) and Duncan Epping (@duncanyb) are the authors of new book which has been released recently. Ben Fathi (CTO of VMware) and Charles Fan (SVP of VMware R&D) did wrote a foreword. By reading the foreword I learned that VSAN as a product was practically ready in June 2013, to be part of the vSphere 5.5, but finally delayed and GA as you already know just few months back with the release of vSphere 5.5 Update 1 earlier this year (March 7).
I've heard few times recently that VMware VSAN is what vMotion was 10 years ago for VMware. It's truly revolutionary product which is capable to turn any vSphere system into hyper-converged storage solution. VSAN is part of ESXi kernel module, it's baked in. Cormac and Duncan working in the VMware storage team has had a good idea to wrote a book about it!
There is 10 chapters in the book which full name is Essential Virtual SAN (VSAN): Administrator's Guide to VMware Virtual SAN. Those 10 chapters are covering most of what of VSAN has to offer and what an IT admin has to know from the design perspective, but also management and troubleshooting perspective.
The book is available at the major online shops like Amazon, Safari etc. The electronic version is already available now for $41.99. The paperback version shall be available later but you can already pre-order now.
VMware vSphere Resource Management Essentials by Jonathan Frappier. This book is up to date guide for VMware administrators willing to start learning VMware technology from the ground up. Jonathan Frappier is an experienced IT professional who holds an advanced VMware certifications like VCAP5-DCD and who writes with passion.
The book is destined to administrators wanting to learn about VMware vSphere and its resources management and automation tools within vSphere. It's a nice topic since everyone does know on how to create and optimize single VM or VMs, but not everyone know how-to manage all the resources present in a cluster or datacenter.
The book isn't very long to read as it only has 4 chapters, but I liked the format where the author present a feature and right after he gives you an examples with screenshots how-to use it in real life! This is not simple theoretical or technical guide, but Jonathan shares his experience and tips that he has learnt so far with vSphere so it's very valuable.
You can also find the book at Amazon.

vSphere PowerCLI Reference – Luc Dekens, Alan Renouf (alias Virt-U-Al), Glenn Sizemore, Anrim van Leishout, Jonathan Medd. I also got a copy and I did a review of the book which you can read on this blog post here. And below a sample review from Amazon.
Although I know vSphere inside out I am a novice when it comes to PowerCLI. The main reason being that I never gave myself the time to actually learn PowerCLI as I figured I could do things faster using the UI. Although this might be true in some cases the first thing the book tought me was that my perception was wrong.
The book shows you how to optimize your day-to-day operations by taking advantage of what PowerCLI has to offer out of the box, but it also teaches you how to create your own functions. The amount of examples in there in terms of PowerCLI scripts are such a valuable asset that I would highly recommend it to anyone who is interested in learning PowerCLI and/or optimizing their operational procedures. Get more details here.
