Has anyone run AD (or ADAM) where the db and logs are on an iSCSI device?

Over on his blog, my mgr Bryce mentions the new iSCSI evaluation going on here in the EEC. I for one don't really understand iSCSI at all. I'm not a hardware guy. :)
However, I do like to talk about directory performance, and I've never seen either AD or ADAM deployed on an iSCSI device. I am going to try and get my hands on some gear and try it out while it is here and see what the numbers look like.

Has anyone else ever tried it? Experiences to share?
