When accessing an iscsi target from Netware 65SP6, from the Netware
perspective are there any performance differences if the target is
configured to have one big LUN or several smaller LUNs (eg does the multi
LUN approach enable any benefits of parallelism ?)

From the target's viewpoint the data would be spread across the same set of
disks regardless of whether a single or multi LUN configuration was adopted.

Any thoughts/comments welcome.
