During the open panel, my question was really specific -
Q) What is the future of a SCSI-target subsystem in linux. Which
target engine/subsystem can we expect?
Your answer) There is place for only 1 target-subsystem in the Linux
scsi stack and in the LSF summit the decision was taken to merge LIO.
Has that
decision changed since the summit?
The decision hasn't been taken to merge LIO, but based on what happened
at the summit, I think it's the most viable candidate and will likely be
merged by 2.6.37
Quick question ... will LIO support SRP? I should probably run over to
their lists and ask, but a quick inspection of their site this morning
shows that they are mostly iSCSI and FC focused. (LIO folks, please
feel free to step up and comment)
I'd certainly like to see a single framework, but not at the cost of
losing important (to us) functionality. We'd like to continue to use
SRP, and iSCSI. We'd like to use iSER (which is in the tgt stack) which
LIO would give us when merged with tgt. We are currently using SCST's
iSCSI and SRP stack within our products.
I believe this also affects the OFED folks, as SRP is one of their
services (based upon SCST).
Any guidance (in a general sense on the target side, not necessarily
specific to LIO) on this would be appreciated. SCST has been a good
system for us to work with. I'd hate to lose its functionality, and
have us be forced to re-engineer some of our backend logic to work
around the missing bits. Thanks!
Regards,
Joe
