[Zope] ZODB file size

What, if any, are the methods of growing a ZODB data store under Zope larger than 2Gig? I'm loosely expecting on the order of 15Gig of data which will need to be directly managed by a Zope instance and have the obvious scalability question. Sadly nothing has sprung up on my googling or wandering of Zope.org. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw@kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.
