Can we buy a NAS device and use it to mount NSS volumes on a NetWare
6.5 server?

We are about to begin archiving GroupWise data. We are going to setup
a isolated LAN with one NetWare 6.5 server running GroupWise. This
server needs at minimal 400GB of disk space to restore our GW system to
it. I need to be able to mount an NSS volume on this server. Could
this volume be on a NAS device or do we need to purchase something else?
