Excellent Book for Datacenter networks
This book seems to be a good reference for IT staff who want

to better understand networking in the datacenter edge segment.

This is the only networking book that I found that covers issues

related to servers, network interface cards and the access

switches and routers.

The book covers important concepts in depth that are not found

anywhere else. For example ch 3 describes how TCP tunable

variables are grouped into functions such as flow control,

congestion control and how they work. In particular this

chapter describes how the data packets are impacted by

the tcp tunable variables, using the Solaris implementation as

example. I always see suggested tunable recommendations in

the manuals, but they never explain how they work. This book

is the first place where I was finally able to understand

how these TCP tunables work. There is also a free sun blueprint

available, that looks like came right out of this book, which

is also available from informIT. It is not only an excellent

description of how tcp tunables work, but helpful when

optimizing performance.

Ch 5 offered some good insights on how the gigabit ethernet

device driver worked. I did not find this anywhere else.

P.139 to 169 contained really nice insights on how the

gigabit ethernet driver works, including the unique

features of the NIC and driver, including a nice description of

how packets are recieved and transmitted. This RX TX architecture

on p.145 and related are not available anywhere else and was

clearly written by an expert who probably wrote the driver

himself. These days marketing staff are the ones writing

print.

Ch 6 and 7 was very useful to us, in the sense it gave us

a great starting point for greenfield deployments of web

based applications. We were able to leverage the designs and

customize for our purposes. On p.326 I found the configs very

useful. For example a desc on how to tie in the port availability to vrrp, allowing the router with the most available ports or links to the servers to be promoted to Master. It is insights like these that IT staff like myself,

found to be very helpful and cleared up a few grey areas.

In summary, this book is probably intended for IT datacenter staff who manage and design networks that fall into to the access layer segment. I want to understand how all the pieces work and inter relate, from the tcp stack, to network interface card to the L2 access switch(various patterns are offered) to the L3 default router(vrrp), appliances such as SSL, loadbalancing etc. This is the only book I found that actually

compared several Load Balancers, Firewalls and SSL appliances and

described how they work. I was able to understand and use it in

our production network!

This is pretty much the material required to deploy web based applications into a network infrastructure.

A complilation of what you can find on the Internet for free
This book has a lot of general information as well as a lot of incredibly detailed information and examples. It is not light reading at all. However, I don’t know that this book really will be of any benefit to anyone except someone who knows networking but has never worked with Sun systems or a Sun user who is migrating to network administration.

Even then, the need for this book is questionable.

The information about the various layers of TCP stack can be found in any TCP/IP primer that is available on the Internet. Even the concepts of Quality of Service and load balancing can be found in many places. Sure, they won’t necessarily be meant specifically for Sun hardware and software, but the principles are the same regardless of which platform you are using.

With respect to Sun hardware and kernel settings, there is nothing in this book that you cannot get for free on the Internet. In fact, most or all of the information in this book regarding the various Sun networking interface cards is on Sun’s technical support web site, SunSolve. Hardware diagrams, hardware specifics, and tunable kernel parameters are all available on SunSolve. There was little or nothing in all of chapter 5 that a quick visit to SunSolve could not have given to me. The only benefit that this book has over SunSolve is that all of the information is in a single book rather than in multiple InfoDocs.

Even concepts of network availability and design are somewhat second-nature to most network administrators, I would think. Perhaps this book will indeed be a help to those who are beginner network administrators. When we all make our first network, it’s almost always a flat network in a single IP range. This book might help to broaden a network administrator’s view to the concepts of multiple subnetting and high availability. But on the other hand a beginner network administrator should not be put in the position to design and implement a highly-available, enterprise-wide network anyway.

The very title of this book is misleading as well. Networking concepts and networking technology are topics that are necessary for any kind of network implementation, regardless of platform and software. Yet this book intentionally limits itself to Sun ONE. Not everyone who has a Sun network uses Sun ONE, nor are the principles of network concepts and technology restricted to networks that are only meant for web services. Many Sun shops use their Sun hardware for databases, data warehousing, and file services that have little or no web integration. This book needlessly suffers from tunnel vision when it would probably have been better served as a general Sun networking manual or even a book that can be used across all types of operating systems with a focus on Sun technology. The subtitle of this book should be A Sun ONE Designer’s Resource.

I can very easily see this book on the shelf of someone who is experienced with Sun from a hardware or operating system point of view but is just starting out with networking. Unfortunately, I can’t see how this book would be of any real value to an experienced Sun network administrator who has fast access to SunSolve, unless (s)he just wants the convenience of not having to go to SunSolve. At a list price of US$46, that administrator must **really** not want to go to SunSolve.

Powerful and Brutal!!!
I stumbled upon this movie 4 days ago. I found this under movies that Marilyn Manson was in, so I clicked on it and the synopsis. It sounded like it had a really good plot, so I ordered it. It was a really good and interesting movie that dealt with drug addiction, child abuse, and child rape! I probably wouldn’t recommend that you watch this with your parents. A drug-addict/hooker named Sarah takes her son, Jeremiah back, but he doesn’t like her, so he runs away. Sarah finds him and gets with an abusive guy that rapes and beats Jeremiah. Jeremiah is sent to live with Sarah’s God-obsessed parents. After three years, Sarah is back and takes Jeremiah with her again. Sarah soon realizes that if she is going to keep her men, then she cannot say Jeremiah is her son, so she persuades him to cross dressing. (Don’t think I’m gay, but I honestly think Jeremiah looked extremely sexy dressed as a girl!) It’s too bad that Marilyn Manson only had a 5 minute cameo, because he was really good. Sarah and Jeremiah go into hiding because she thinks everyone is after them. She makes him think that certain foods are poisoned and makes him drink ipecac. Asia Argento, and the Sprouse brothers did an awesome job. Asia also did a great job at directing. If you love child abuse, drugs, and cross dressing kids, you’ll love THE HEART IS DECEITFUL ABOVE ALL THINGS!!!

OMG!
This movie is really disturbing, and really sad. You feel for the boy. The movie drifts off a bit. And you totaly hate the mother for her behavior/ choices she makes through out the film.

The Heart Is Deceitful Above All Things
I Thought It Was Very Well Thought Of, And Very Well Made, Although Clips Where Cut, Which I Was Quite Frustrated.

The Kids Acting in the movie was Excelently well Performed And The Movie Touched Me, because I Went Though Almost The Same Ordeal.

My Wife and I Cried,

Great Actors, Horrible Film
Well, if there is one positive thing to mention about this movie, it’s that there are some great actors here and they do a good job with what they are provided. The problem is that the story is boring and it goes nowhere. I understand that some great movies can be about ugly topics, but to become great in this genre, they need to excel. This movie was just one scene after the next of bad things happening, with no real emotion about it all and no point or thought provoked by it. Very disappointing.

Devastatingly beautiful if somewhat distressing
This DVD is distressing in an educational sort of way…..it gives one pause to consider the lives that some vulnerable young people are forced to lead and how vulnerable their parents can also be in these circumstances…the life of the parent inevitably impacts on the life of the child and yet to see this young boy adapt to changing circumstances is not only a cause for concern, but hope, too!
