Max Chunk Size

Question regarding Informix 2GB max chunk size. We are configuring a 7.2x environment (probably will be 7.22 and definitely on a Sun Enterprise 4000). We have about 14 production databases. We will be working with 6 x 4.2 GB of space. We have always been under the assumption that it was better to isolate each database to it's own dbspace so we can better "control" each database. However that means alot of "carving" of space. It was then suggested to us that we should configure max chunk size for all the disk space and basically put all databases out there (of course being aware of what goes where for performance reasons) creating each dbspace containing a 2GB chunk and several databases per dbspace. Can anyone offer good, sound arguments in favor of one or the other? We appreciate any helpful information offered.
