I was actually reading about the T10 spec just the other day. Getting a standard that any OS vendor can implement along with any storage vendor without adding a 3rd party (like Symantec) would definitely be ideal. I just wish new features like these would be back ported to older Operating Systems. Windows 2008 has some volume shrink features for example that can help with thin provisioning and page reclaim.. But that means I'd have to move my entire environment up to Windows 2008 to take good advantage of it. Large environments can't usually justify upgrading their software every time a new feature is added, even if that feature can save them money. Thanks Vaughn..

This will help move the ball forward beyond availability only with VXFS here or NTFS there. Nice write up.

I DID find information on using Windows 2008 Volume shrink in Disk Administrator to shrink CLARiiON LUNs. This requires FLARE 29 and Windows 2008 though.
