iSCSI LUN sharing

[Marti, Robert]

You'd be able to just install additional software.

The problem with just using NFS or Samba to share the data out is that now you've got Box B's job relying on Box A's existence.  If they can both see the same data, they're relying on the existence of the data, which is usually easier to provide.

Thanks, Rob.

If I get an AP entitlement, would I have to re-install the OS or would I be
able to just install the GFS stuff I needed?
