Extended Parallel Server can fragment tables and indexes across disks that belong to different coservers. Each table fragment can reside in a separate dbspace that is associated with physical disks that belong to different coservers. A dbslice provides the mechanism to manage many dbspaces across multiple coservers. Once you create the dbslices and dbspaces, you can create tables and indexes that are fragmented across multiple coservers.

For information on the advantages of fragmenting tables across coservers, see your IBM Informix: Extended Parallel Server Performance Guide. For information about how to create dbslices and dbspaces, see your IBM Informix: Extended Parallel Server Administrator's Guide.
