Book Review: Grow a Greener Data Center

Grow a Greener Data Center by Douglas Alger
What It Is
In a nutshell
This book discusses energy efficiency and how to measure what “green” means in the context of a data center. Furthermore, it discusses current methods to make data centers greener from both the facilities and IT perspectives.
Organization
There are 10 chapters but I will group them as below:
- Chapters 1 and 2 (Basics of Green and Measuring): This group of chapters discusses the fundamental questions of what green is and how to measure the degree of greenness. A noteworthy point is that international activities, regulations and metrics are included in addition to those of the U.S.
- Chapters 3, 4, 5, 6, and 7 (Facilities focus): This group of chapters discusses a comprehensive coverage on buildings, power, cooling, cabling, and refrigerants and fire suppressants from the energy efficiency perspective.
- Chapters 8 and 9 (IT focus): This group consists of a short chapter on IT hardware energy efficiency [chapter 8] and chapter 9 of comprehensive coverage on IT from consolidation and virtualization viewpoints.
- Chapter 10 (Greening beyond Data Centers): This chapter covers somewhat miscellaneous but relevant information such as e-waste.

Review
The book contains timely and invaluable information on the issue of greening data centers. Each chapter contains appropriate and ready-to-apply subject matters. For example, the power section covers the IT gears impacts, power/GHG emission relationship, renewable energies, PDU/UPS efficiency, generators, lighting and overhead/underneath access. In addition, the cooing section discusses heat recovery/reuse, economizer, VFD, air/water, CFD and sealing gaps.
I was pleasantly surprised that the IT coverage was not skimpy but included discussions on consolidation/virtualization were given to cover all three of the IT gears, namely server, storage and network. The chapter 9 alone can be a good material to discuss some part of the state-of-the-art at a data center in the IT context.
Room for improvement or extension
Even though Alger covered the state of the art in both facilities and IT, I would like him to extend to cover software from the energy efficient perspective, maybe in a separate book or report.
After physical entities, such as facilities and IT hardware, are taken care of, the next step is to make software more energy efficient. Reference: I recently chaired a session on this topic.

| PayPal UK Launch Security Key - Guest Posting from PayPal I am happy to say they are using VeriSign Identity Protection to deliver this, which means that PayPal Customers will be able to use their token at other sites who join the VIP network. PayPal are the first UK members of the network, but there are around 30 other members in different countries around the world so you can expect to see more places where you can use your token in the UK appearing shortly. Facebook scam - Part 2 This just in from the BBC web site, Symantec have identified a virus that steals user names and passwords, nothing new there. But, if I understand this right, it is delivered through a Facebook invitation from someone you don't know and delivers malware which can then steal user names / passwords and also keylog credit card info. Survey finds passwords are not secure - well d'uh! I don't think the vendor community has been crying wolf about the problems that stronger authentication solves, more like highlighting that this problem is here and growing. Well the discussion I have had recently with many different organisations across many different industries are now resulting in more and more consumer projects in this area |
