My column this week (which I can't link to right now, thanks to a bug at the Windows &.NET web site) was on iSCSI and Exchange. A helpful MS PR person wrote to point out an error: there's not actually a separate "certified for Exchange logo". If an iSCSI device has the "Designed for Windows" logo, it's supported for use with Exchange.

Update: it turns out that the Windows Catalog uses the "Designed for Windows XP" logo for iSCSI devices. Even though the column, and the press release which inspired it, talk about the "Designed for Windows" logo, those products listed in the catalog are certified for use with Exchange 2003.
