IIRC, he is the chief architect for polyserve, which makes...HA NAS filesystem software/utilities. I know some people run ASM on NAS, but it always seemed a bit kludgy to me. From what I have read by him (other whitepapers in addition to the link you provided), he is a really smart guy, it just looks like he may not be completely unbiased.

We have a 2.5TB non RAC data warehouse on ASM (which lives on an EMC DMx), and we get 6-7ms single block reads with no performance/availability issues at all. I understand the need to diversify your vendors, but I also see value in the firm that provides the RDBMS software also providing the filesystem to which the RDBMS I/O requests will be made.
