I thought the book was well written, but sadly reflects the problems with the transition from Sun to Oracle. Internal URLs/links in the book point to the now defunct SUN domain - so less than helpful.
There seemed to be massive differences in emphasis in sections with the 1st 3rd of the book going into detail on specific hardware arrangements and other sections just fizzling out like the author didn't want to put the effort in to finish it.
All in all, if this were re-written with updated references, it would be better and also I wonder if it would have been better split across the different topics with more effort in the LDOMS area. It is however a good book, it does have gaps for me, but I found it very useful.
