I don't often get involved with storage issues unless it is affecting one of my customer's websites in some way (usually performance, though could be a hang).
During an issue I am currently working on, I came across the FileCab blog of the Windows Storage team.
There are lots of great articles there and also links out to other blog posts of interest, such as these ones of Jose Barreto about the SMB2 protocol which is new to Windows Vista and Windows Server 2008:
SMB2, a complete redesign of the main remote file protocol for Windows
File Server performance improvements with the SMB2 protocol in Windows Server 2008
