Hi Adam,

GPFS nodes can be licensed in two different ways.  As a node with storage locally \
attached (called NSDs), or as a client node that connects to NSD servers.

My Virtual servers are client nodes, and thus have an appropriate client license \
(these are cheap).  They connect via GPFS's RDMA over Infiniband to my GPFS NSD \
servers which are a much more expensive license.

The purpose of me doing it this way was to let me use storage already allocated to \
GPFS for my cluster without having to dedicate any luns to Virtual servers.

Cheers, Evan.
