Straight from Duncan Epping’s blog site: As multiple people asked for it, Frank and I decided to also put the 4.1 HA/DRS Deepdive on sale. Just wanted to inform you guys about it. Here are the links: vSphere 4.1 HA/DRS Deepdive – £4.59 Once again, please note that Amazon might charge extra if you are ordering/downloading the book from remote. We cannot control that unfortunately. Never the less, this is the bargain of the year for sure when it comes to VMware books. No book out their with such an insane price/page/quality ratio!
