Sorry that I haven't been more transparent in what I'm currently
working on with the target. I've been kind of heads down.
Current things in the pipe line are:
(1) Integration with ZFS
Looking to add support such that when someone creates
a ZVOL they can set a property called shareiscsi=on
which will do the back ground work of creating an iSCSI
target.
(2) iSNS client support
This will enable the iSCSI target to communicate with
an iSNS server and register which targets are being
exported and receive a list of initiators that are
aloud to connect to the target.
(3) Persistent Reservation
The iSCSI Target currently supports the old SCSI-2
RESERVE/RELASE (it was easy). We need to really support
the PGR commands and it'll take a little more work.
This is a must have for Sun Cluster support. Other OS's
may use PGR, but I know that SC needs this support to
enable more than 2 nodes per cluster.
(4) Sun Cluster Support
Target failover.
(5) MC/S and ERL=2
The higher error recover and multiple connections
per session are nice to have, but not really required
for disk operations. For Tape operations though this
is a must have.
#1 and #2 are the top priorities right now. #4 and #5 might move
ahead of #3 depending on resources available.
Some of the other features that I'm looking to add, but need to
prioritize are:
- FC Target mode
- T10 Data Integrity
- iSER
- LOFI support for partitions
- OSD Emulation
- Media Changer
- LUN Expansion
- Performace enhancements over slow links
- Performace enhancements to reduce latency
- per port IPsec
Hope this helps.

There has been very little news about the day-to-day work on both
projects and updates about whats improving, performance
improvements, etc. Since more and more of us are looking seriously
at putting the iSCSI Target into production enviroments it'd be
great to have more transparency on the work being done.
