Novell's documentation says that their Dynamic Storage Technology is:

Novell® Dynamic Storage Technology (DST) for Novell Open Enterprise
Server 2 (OES 2) Linux is an information life-cycle management
technology that uses a policy-based approach for relocating data between
two Novell Storage Services™ (NSS) volumes located on different devices,
and transparently provides a unified view of the file tree to users. different devices, does that mean two different servers? Or same
server, different hard drives? Some of the examples they present sounds
like different servers, such as a NAS and a real server? Anybody know?
