Gianluca,
Are you sure your 10Gbit nics doesn’t support iSCSI offload?
I Pavel, thanks for the comment.
It could be a nice way to proceed ;-) Are you using it with oVirt?
Some considerations/questions:
- in the past I tested iSCSI offload with RH EL 5.5 (it was late 2010) with
some problems; then I also tested with RH EL 6 when still in beta with
better results. Not tested more anddidn't go to production as it was not
considered crucial. Can we consider it stable in RH EL / CentOS 7.3?
- I remeber that at 5.5 / 6beta times even when configuring offload iSCSI
you still needed to configure an ip on the interfaces in OS, because I seem
to rememebr the discovery phase (or login perhaps?) happened on tcp and not
capable in offload. Is this still true or can I only configure an ip for
the offload macs?
- is the offload configuration transparent to oVirt in the sense that oVirt
only needs that the hosts see the multipath iSCSI devices, or do I need to
make any particular config in oVirt too, then?
Thanks in advance,
Gianluca
