BTW, does anybody know a paper about doing some DB ops directly on disc controllers? The other day my former colleague mentioned that he come across such paper (maybe a blog post?), but we couldn't find it. It's really interesting idea and I believe it's doable, although under very specific circumstances (disc vendor specific, sectors layout aligned to DB needs, etc.).
