iSCSI and scsi-mq

iSCSI and scsi-mq

[Johannes Thumshirn]

Hi iSCSI experts,

I've been starting to research possible implementations of a scsi-mq capable
iSCSI. With my research I found the following thread https://groups.google.com/
forum/#!msg/open-iscsi/qLaXJh2Gqt4/A2NIDZ0fT9oJ and wondered what happened to
the efforts layed out there (and what have been the results of the discussion
at LSF/MM).

The one TCP connection per CPU or HW queue approach sounds particularly
interesting to me when taking a SW iSCSI initiator. A problem Hannes pointed
out here could be network topology changes which result in a different route on
a different NIC with a different number of HW queues, so it might not be the
ultimate solution.

With the offload cards we might need to do something else.

Is there anyone else working on a scsi-mq for iSCSI at the moment and is
willing to join efforts here?

Byte,
	Johannes
