A couple of weeks ago I wrote about the availability of a technical document and a webcast about Storage Design for Exchange Server 2007.

The correspondig podcast is now available to download: How Microsoft IT Implemented New Storage Designs for Exchange Server 2007.

Overview
How does Exchange Server 2007 enable a large enterprise to increase mailbox quotas globally by a factor of ten and still lower storage costs, reduce maintenance complexities, and simplify data recovery processes? Microsoft IT was able to take advantage of Cluster Continuous Replication (CCR) in new mailbox server designs based on direct attached storage (DAS). Advantages of CCR and DAS over alternative configurations will be discussed along with how MSIT was able to eliminate storage as a single point of failure while at the same time lowering costs to two dollars per gigabyte.
