A couple weeks back, the talented (and fellow Exchange MVP) Jim McBee blogged about his new free ebook on Exchange storage sizing. I've just had the opportunity to peruse it -- in fact, I've been reading through it most of yesterday and today -- and I am unashamed to say this is a fantastic book.
Jim focuses on Exchange 2007 but gives plenty of comparison back to the equivalent Exchange 2003 issues. The result is a thorough and accessible tour of all the various factors that go into sizing Exchange storage, complete with pointers on all the pain points, gotchas, and best practices the Exchange community has assembled over the years. I've certainly learned a thing or two already and I'm not even done with the book yet.
You can follow my link to Jim's blog announcement above (while you're at it, read his blog if you don't already -- and if you don't, why are you reading me and not him too?) or skip straight to the book's website and registration page. Either way, though, it's a complete download for a quick free registration. I'll be printing mine out, 3-ring binding it, and putting it on my shelf for future reference. It's that good.
