In the first part of "Geek Out with Perry" video series, discussed how improving IO efficiency has enabled us to get closer to providing large low cost mailboxes. However, providing large mailboxes to end users sparks a lot of interesting issues and questions; if you’ve a lot more data, how do you deal with longer back up times and how do you recover quickly from failures? Data protection is an area where we've invested in heavily in order to enable larger mailboxes. In this next "Geek Out with Perry" video embedded, Perry chats regarding how we’ve evolved our thinking around storage and data protection for Exchange,” noted Microsoft Exchange team.

Also, Perry posted regarding his take on virtual storage “yes Exchange 2010 should seem a little snappier on the similar hardware compared to Exchange 2007 and especially compared to 2003. But the snappiness should be almost a small side effect of the overall IO efficiency improvements if the hardware was properly sized for the original version. Overall we have seen an improvement of 2-4x in the number of io's necessary to support a given user profile between 2007 and 2010,” read Storage performance and my take on virtual storage.
