Summary
.LP
N_Port_ID Virtualization (NPIV) allows one Fibre Channel port to represent
many physical ports, thus virtualizing the hardware.  NPIV is especially
useful for virtual machine environments.

.NH 2
Configuration and Locking
.LP
During inception, several questions were raised about a configuration file,
and locking of the configuration database.  The project team decided to change
to use standard libscf(3LIB) APIs for this, resolving the issue suitably.
.NH 2
Daemon Startup
.LP
During inception, a question was raised pertaining to daemon startup.  The
project team's response is that SMF is used to start the deamon, and only
for Xen.
.NH 2
NPIV Configuration and Zones
.LP
During inception a member asked what the administrative experience would be
for a zone when an NPIV device is configured for the zone, but the underlying
HBA doesn't support NPIV.  Offline, the project team decided to reduce the
scope of the project to exclude zones.  This question will need to be answered
in another case if/when the project team revisits support for zones.
.NH 2
Relationship to Other Virtualized IO Projects
.LP
A member raised a concern about the relationship of this project to other
projects, such as Crossbow, which are also providing facilities for IO
virtualization.  The project team examined Crossbow in particular, and found
some similarities, but there were enough differences as well.  No action to
unify interfaces between networking and storage virtualization was requested,
and none was taken.
