Clustering support?

I'm trying to put together a table showing the database systems that support clustering and the open-systems hardware platforms they support it on. I've found that Oracle supports clustering via the Parallel Server feature in V7.0, but I'm in the dark as to whether Informix has a similar capability. Can anybody in this newsgroup tell me if Informix supports clustering, and if so, on which open-systems platforms? Thanks! -- Mark A.
